Let's divide 86748876 by 850
We want to divide 86748876 by 850.

Going ahead to step 1:
If we divide 8 by 850, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 850

Let's proceed to step 2:
The number 850 fits into 86 0 times, leaving a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Fetch the next digit (7) from the dividend, attach it to 86 and continue: 867 / 850

Going ahead to step 3:
If we divide 867 by 850, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 850 from 867, we get 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 850

Step 4:
The number 850 fits into 174 0 times, leaving a remainder of 174.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 174 to get 174.
Take the next digit (8) from the dividend and append it to 174, then repeat: 1748 / 850

On to step 5:
1748 divided by 850 is 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
The remainder is 48 after subtracting 1700 from 1748.
Fetch the next digit (8) from the dividend, attach it to 48 and continue: 488 / 850

Going ahead to step 6:
488 divided by 850 is 0 with a remainder of 488.
The number 0 becomes the next digit in our result. 
Result so far: 1020.0
If we subtract 0 from 488, we get 488.
Include the next digit (7) from the dividend after 488, then repeat: 4887 / 850

Moving on to step 7:
If we divide 4887 by 850, we get 5 and a remainder of 637.
Use 5 as the next digit of our solution. 
Result so far: 10205.0
If we take 4250 away from 4887, we end up with 637.
Take the next digit (6) from the dividend and append it to 637, then repeat: 6376 / 850

Step 8:
6376 divided by 850 is 7 with a remainder of 426.
Record the quotient 7 as the next digit in the result. 
Result so far: 102057.0
Deduct 5950 from 6376 and we're left with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Advancing to step 9:
If we divide 4260 by 850, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 102057.5
Subtract 4250 from 4260 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
850 goes into 100 0 times with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 102057.5
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
1000 divided by 850 is 1 with a remainder of 150.
The number 1 becomes the next digit in our result. 
Result so far: 102057.501
Deduct 850 from 1000 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 12:
The number 850 fits into 1500 1 times, leaving a remainder of 650.
Record the quotient 1 as the next digit in the result. 
Result so far: 102057.5011
If we take 850 away from 1500, we end up with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

The final outcome is 102057.5011, with a leftover of 0.0065.
