We're dividing 86111191 by 850 
We want to divide 86111191 by 850.

Going ahead to step 1:
The number 850 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 850

Advancing to step 2:
When dividing 86 by 850, we get 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (1) from the dividend after 86, then repeat: 861 / 850

Let's proceed to step 3:
850 can be fit into 861 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 850 from 861 to get 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 850

On to step 4:
The number 850 fits into 111 0 times, leaving a remainder of 111.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 111 after subtracting 0 from 111.
Bring next digit (1) of the dividend behind the 111 and repeat the process: 1111 / 850

Step 5:
1111 divided by 850 is 1 with a remainder of 261.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Deduct 850 from 1111 and we're left with 261.
Bring next digit (1) of the dividend behind the 261 and repeat the process: 2611 / 850

Going ahead to step 6:
The number 850 fits into 2611 3 times, leaving a remainder of 61.
Write down 3 as next digit of the result. 
Result so far: 1013.0
If we subtract 2550 from 2611, we get 61.
Append the next digit (9) from the dividend to 61 and continue with: 619 / 850

Let's proceed to step 7:
850 can be fit into 619 0 times, resulting in a remainder of 619.
Use 0 as the next digit of our solution. 
Result so far: 10130.0
The remainder is 619 after subtracting 0 from 619.
Grab the next digit (1) from the dividend, add it to 619, then carry on: 6191 / 850

Step 8:
If we divide 6191 by 850, we get 7 and a remainder of 241.
The next digit of our result is 7. 
Result so far: 101307.0
If we subtract 5950 from 6191, we get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Going ahead to step 9:
When dividing 2410 by 850, we get 2 with a remainder of 710.
Record the quotient 2 as the next digit in the result. 
Result so far: 101307.2
The remainder is 710 after subtracting 1700 from 2410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Moving on to step 10:
The number 850 fits into 7100 8 times, leaving a remainder of 300.
Use 8 as the next digit of our solution. 
Result so far: 101307.28
If we take 6800 away from 7100, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 11:
850 goes into 3000 3 times with a remainder of 450.
Use 3 as the next digit of our solution. 
Result so far: 101307.283
Subtract 2550 from 3000 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 12:
If we divide 4500 by 850, we get 5 and a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 101307.2835
If we subtract 4250 from 4500, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 13:
When dividing 2500 by 850, we get 2 with a remainder of 800.
Put 2 as the next digit of the answer. 
Result so far: 101307.28352
If we subtract 1700 from 2500, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Moving on to step 14:
The number 850 fits into 8000 9 times, leaving a remainder of 350.
Put 9 as the next digit of the answer. 
Result so far: 101307.283529
Subtracting 7650 from 8000 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 15:
If we divide 3500 by 850, we get 4 and a remainder of 100.
Write down 4 as next digit of the result. 
Result so far: 101307.2835294
If we subtract 3400 from 3500, we 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 16:
850 can be fit into 1000 1 times, resulting in a remainder of 150.
Write down 1 as next digit of the result. 
Result so far: 101307.28352941
If we subtract 850 from 1000, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final result is 101307.28352941 with a remainder of 1.5e-07.
