Let's divide 39886556 by 255
We want to divide 39886556 by 255.

On to step 1:
255 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 255

Going ahead to step 2:
If we divide 39 by 255, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 255

On to step 3:
255 can be fit into 398 1 times, resulting in a remainder of 143.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 255 from 398 to get 143.
Take the next digit (8) from the dividend and append it to 143, then repeat: 1438 / 255

Advancing to step 4:
When dividing 1438 by 255, we get 5 with a remainder of 163.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 1275 from 1438 to get 163.
Take the next digit (6) from the dividend and append it to 163, then repeat: 1636 / 255

Step 5:
If we divide 1636 by 255, we get 6 and a remainder of 106.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
If we subtract 1530 from 1636, we get 106.
Fetch the next digit (5) from the dividend, attach it to 106 and continue: 1065 / 255

Going ahead to step 6:
1065 divided by 255 is 4 with a remainder of 45.
The next digit of our result is 4. 
Result so far: 1564.0
If we take 1020 away from 1065, we end up with 45.
Include the next digit (5) from the dividend after 45, then repeat: 455 / 255

Moving on to step 7:
255 can be fit into 455 1 times, resulting in a remainder of 200.
Record the quotient 1 as the next digit in the result. 
Result so far: 15641.0
Subtract 255 from 455 to get 200.
Append the next digit (6) from the dividend to 200 and continue with: 2006 / 255

Going ahead to step 8:
255 goes into 2006 7 times with a remainder of 221.
Use 7 as the next digit of our solution. 
Result so far: 156417.0
If we subtract 1785 from 2006, we get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Step 9:
2210 divided by 255 is 8 with a remainder of 170.
The number 8 becomes the next digit in our result. 
Result so far: 156417.8
Deduct 2040 from 2210 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 10:
255 can be fit into 1700 6 times, resulting in a remainder of 170.
Write down 6 as next digit of the result. 
Result so far: 156417.86
If we take 1530 away from 1700, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 11:
When dividing 1700 by 255, we get 6 with a remainder of 170.
Write down 6 as next digit of the result. 
Result so far: 156417.866
If we subtract 1530 from 1700, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final outcome is 156417.866, with a leftover of 0.017.
