We look at the division of 71205349 by 851 
We're looking to find how many times 851 goes into 71205349.

Step 1:
851 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 851

Moving on to step 2:
851 goes into 71 0 times with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Bring next digit (2) of the dividend behind the 71 and repeat the process: 712 / 851

Going ahead to step 3:
The number 851 fits into 712 0 times, leaving a remainder of 712.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 712 after subtracting 0 from 712.
Fetch the next digit (0) from the dividend, attach it to 712 and continue: 7120 / 851

Going ahead to step 4:
851 goes into 7120 8 times with a remainder of 312.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 6808 from 7120 to get 312.
Include the next digit (5) from the dividend after 312, then repeat: 3125 / 851

Advancing to step 5:
851 can be fit into 3125 3 times, resulting in a remainder of 572.
Write down 3 as next digit of the result. 
Result so far: 83.0
Deduct 2553 from 3125 and we're left with 572.
Append the next digit (3) from the dividend to 572 and continue with: 5723 / 851

Going ahead to step 6:
If we divide 5723 by 851, we get 6 and a remainder of 617.
Put 6 as the next digit of the answer. 
Result so far: 836.0
The remainder is 617 after subtracting 5106 from 5723.
Bring next digit (4) of the dividend behind the 617 and repeat the process: 6174 / 851

On to step 7:
851 goes into 6174 7 times with a remainder of 217.
Write down 7 as next digit of the result. 
Result so far: 8367.0
Subtracting 5957 from 6174 leaves us with 217.
Include the next digit (9) from the dividend after 217, then repeat: 2179 / 851

On to step 8:
If we divide 2179 by 851, we get 2 and a remainder of 477.
Record the quotient 2 as the next digit in the result. 
Result so far: 83672.0
If we subtract 1702 from 2179, we get 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Let's proceed to step 9:
When dividing 4770 by 851, we get 5 with a remainder of 515.
Put 5 as the next digit of the answer. 
Result so far: 83672.5
Subtracting 4255 from 4770 leaves us with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Advancing to step 10:
851 goes into 5150 6 times with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 83672.56
Deduct 5106 from 5150 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
851 can be fit into 440 0 times, resulting in a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 83672.56
Subtract 0 from 440 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 12:
The number 851 fits into 4400 5 times, leaving a remainder of 145.
The next digit of our result is 5. 
Result so far: 83672.5605
The remainder is 145 after subtracting 4255 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 13:
The number 851 fits into 1450 1 times, leaving a remainder of 599.
Put 1 as the next digit of the answer. 
Result so far: 83672.56051
If we take 851 away from 1450, we end up with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Going ahead to step 14:
851 can be fit into 5990 7 times, resulting in a remainder of 33.
The next digit of our result is 7. 
Result so far: 83672.560517
If we subtract 5957 from 5990, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 15:
851 can be fit into 330 0 times, resulting in a remainder of 330.
Use 0 as the next digit of our solution. 
Result so far: 83672.560517
Subtracting 0 from 330 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 16:
851 can be fit into 3300 3 times, resulting in a remainder of 747.
The next digit of our result is 3. 
Result so far: 83672.56051703
If we subtract 2553 from 3300, we get 747.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7470, and continue the process.

The final result is 83672.56051703 with a remainder of 7.47e-07.
