318857 ÷ 89 
We want to figure out the number of times 318857 can be divided by 89.

Step 1:
The number 89 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 89

Going ahead to step 2:
89 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 89

Advancing to step 3:
89 can be fit into 318 3 times, resulting in a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 51 after subtracting 267 from 318.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 89

Advancing to step 4:
The number 89 fits into 518 5 times, leaving a remainder of 73.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Deduct 445 from 518 and we're left with 73.
Include the next digit (5) from the dividend after 73, then repeat: 735 / 89

Advancing to step 5:
735 divided by 89 is 8 with a remainder of 23.
The next digit of our result is 8. 
Result so far: 358.0
If we take 712 away from 735, we end up with 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 89

Moving on to step 6:
89 can be fit into 237 2 times, resulting in a remainder of 59.
Write down 2 as next digit of the result. 
Result so far: 3582.0
Subtract 178 from 237 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
If we divide 590 by 89, we get 6 and a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 3582.6
The remainder is 56 after subtracting 534 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 8:
The number 89 fits into 560 6 times, leaving a remainder of 26.
The next digit of our result is 6. 
Result so far: 3582.66
If we take 534 away from 560, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 3582.66 and a remainder of 0.026.
