Ada 23 biji epal. Setiap bakul diisi 4 biji. Berapakah bakul yang penuh? Berapakah epal yang berbaki?
23 ÷ 4 = 5 baki 3

余数 = baki
有时候一个数不能刚好平分完,分完以后剩下一些,剩下的叫余数,马来文写作 baki。23 个苹果每篮放 4 个:可以放满 5 篮(用了 20 个),还剩 3 个 → 23 ÷ 4 = 5 baki 3。
例子:14 ÷ 3 = 4 baki 2,因为 3 × 4 = 12,14 − 12 = 2。
注意:余数一定要比除数小。
remainder = baki
Sometimes a number cannot be shared exactly and some is left over; what is left is the remainder, written baki in Malay. 23 apples, 4 in each basket: 5 full baskets use 20 apples and 3 are left → 23 ÷ 4 = 5 baki 3.
Example: 14 ÷ 3 = 4 baki 2, because 3 × 4 = 12 and 14 − 12 = 2.
Watch out: the remainder must always be smaller than the number you divide by.

Semak: 6 × 80 + 5 = 485 ✔
有余数的长除法 = bahagi panjang dengan baki
百位 4 比 6 小,不够除,所以看前两位 48:48 ÷ 6 = 8,写在十位上;6 × 8 = 48,没有剩。把个位 5 带下来,5 比 6 小,商写 0,5 就是余数。答案 80 baki 5。
例子:58 ÷ 3 = 19 baki 1。
注意:检查方法是 除数 × 商 + 余数 = 被除数。
long division with a remainder = bahagi panjang dengan baki
The hundreds digit 4 is less than 6, so look at 48: 48 ÷ 6 = 8, written above the tens; 6 × 8 = 48, nothing left. Bring down the 5; 5 is less than 6, so write 0, and 5 is the remainder. The answer is 80 baki 5.
Example: 58 ÷ 3 = 19 baki 1.
Watch out: check with divisor × answer + remainder = starting number.

Digit yang berbaki
6 475 ÷ 10, ÷ 100, ÷ 1 000
6 475 ÷ 10 = 647 baki 5
6 475 ÷ 100 = 64 baki 75
6 475 ÷ 1 000 = 6 baki 475
除以 10、100、1 000 的余数 = baki bahagi 10, 100, 1 000
同一个数 6 475:除以 10,最后一位 5 是余数,前面的 647 是商;除以 100,最后两位 75 是余数,商是 64;除以 1 000,最后三位 475 是余数,商是 6。除数有几个 0,就从右边留几位做余数。
例子:3 106 ÷ 10 = 310 baki 6;÷ 100 = 31 baki 6;÷ 1 000 = 3 baki 106。
注意:余数要比除数小:除以 100 的余数最多是 99。
remainders when dividing by 10, 100, 1 000 = baki bahagi 10, 100, 1 000
The same number 6 475: divided by 10, the last digit 5 is the remainder and 647 is the answer; by 100, the last two digits 75 are the remainder and the answer is 64; by 1 000, the last three digits 475 are the remainder and the answer is 6. The number of zeros in the divisor tells you how many digits on the right make the remainder.
Example: 3 106 ÷ 10 = 310 baki 6; ÷ 100 = 31 baki 6; ÷ 1 000 = 3 baki 106.
Watch out: the remainder is smaller than the divisor, so dividing by 100 leaves at most 99.
Cuba kira
37 ÷ 5 = ?
找最接近的积 = cari hasil darab yang hampir
5 的乘法里,不超过 37 的最大积是 5 × 7 = 35,所以商是 7;37 − 35 = 2,余数是 2。6 baki 7 不对,因为余数 7 比 5 大,还可以再分一次。
例子:29 ÷ 4 = 7 baki 1。
注意:余数一定要比除数小。
find the closest product = cari hasil darab yang hampir
In the 5 times table, the biggest product not over 37 is 5 × 7 = 35, so the answer is 7 and 37 − 35 = 2 is the remainder. 6 baki 7 is wrong because 7 is bigger than 5, so another group could be made.
Example: 29 ÷ 4 = 7 baki 1.
Watch out: the remainder must be smaller than the divisor.

3 比 7 小,看 36:36 ÷ 7 = 5 余 1;带下 2 成 12:12 ÷ 7 = 1 余 5;带下 8 成 58:58 ÷ 7 = 8 余 2。答案 518 baki 2。检查:7 × 518 + 2 = 3 626 + 2 = 3 628 ✔。
例子:1 234 ÷ 4 = 308 baki 2。
注意:最后剩下的 2 不能忘记写。
bring down and divide = bawa turun dan bahagi
3 is less than 7, so use 36: 36 ÷ 7 = 5 r 1; bring down 2 to make 12: 12 ÷ 7 = 1 r 5; bring down 8 to make 58: 58 ÷ 7 = 8 r 2. The answer is 518 baki 2. Check: 7 × 518 + 2 = 3 626 + 2 = 3 628 ✔.
Example: 1 234 ÷ 4 = 308 baki 2.
Watch out: do not forget to write the remainder 2.

4 395 ÷ 100 = ?
除以 100 = bahagi 100
除以 100,最后两位 95 是余数,前面的 43 是商:4 395 ÷ 100 = 43 baki 95。439 baki 5 是除以 10 的答案;4 baki 395 是除以 1 000 的答案。
例子:2 718 ÷ 100 = 27 baki 18。
注意:检查:43 × 100 + 95 = 4 395 ✔。
divide by 100 = bahagi 100
Dividing by 100, the last two digits 95 are the remainder and 43 is the answer: 4 395 ÷ 100 = 43 baki 95. 439 baki 5 is for ÷ 10 and 4 baki 395 is for ÷ 1 000.
Example: 2 718 ÷ 100 = 27 baki 18.
Watch out: check: 43 × 100 + 95 = 4 395 ✔.
