We divide 86129581 by 856
We're looking to find how many times 856 goes into 86129581.

Moving on to step 1:
856 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 856

Going ahead to step 2:
856 can be fit into 86 0 times, resulting in a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Take the next digit (1) from the dividend and append it to 86, then repeat: 861 / 856

On to step 3:
861 divided by 856 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 856 from 861 leaves us with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 856

Step 4:
856 can be fit into 52 0 times, resulting in a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 52 after subtracting 0 from 52.
Include the next digit (9) from the dividend after 52, then repeat: 529 / 856

Advancing to step 5:
529 divided by 856 is 0 with a remainder of 529.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Deduct 0 from 529 and we're left with 529.
Take the next digit (5) from the dividend and append it to 529, then repeat: 5295 / 856

Going ahead to step 6:
856 goes into 5295 6 times with a remainder of 159.
The number 6 becomes the next digit in our result. 
Result so far: 1006.0
If we take 5136 away from 5295, we end up with 159.
Bring next digit (8) of the dividend behind the 159 and repeat the process: 1598 / 856

Going ahead to step 7:
When dividing 1598 by 856, we get 1 with a remainder of 742.
The number 1 becomes the next digit in our result. 
Result so far: 10061.0
Subtract 856 from 1598 to get 742.
Grab the next digit (1) from the dividend, add it to 742, then carry on: 7421 / 856

Going ahead to step 8:
The number 856 fits into 7421 8 times, leaving a remainder of 573.
Use 8 as the next digit of our solution. 
Result so far: 100618.0
The remainder is 573 after subtracting 6848 from 7421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Advancing to step 9:
856 goes into 5730 6 times with a remainder of 594.
Record the quotient 6 as the next digit in the result. 
Result so far: 100618.6
If we take 5136 away from 5730, we end up with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Step 10:
If we divide 5940 by 856, we get 6 and a remainder of 804.
The next digit of our result is 6. 
Result so far: 100618.66
Deduct 5136 from 5940 and we're left with 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

After the division, we end up with 100618.66 and a remainder of 0.804.
