We divide 71409370 by 851
We want to divide 71409370 by 851.

Moving on to step 1:
When dividing 7 by 851, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
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

Step 2:
If we divide 71 by 851, we get 0 and a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Take the next digit (4) from the dividend and append it to 71, then repeat: 714 / 851

On to step 3:
When dividing 714 by 851, we get 0 with a remainder of 714.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 714 leaves us with 714.
Include the next digit (0) from the dividend after 714, then repeat: 7140 / 851

On to step 4:
7140 divided by 851 is 8 with a remainder of 332.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 6808 from 7140 leaves us with 332.
Bring next digit (9) of the dividend behind the 332 and repeat the process: 3329 / 851

Advancing to step 5:
If we divide 3329 by 851, we get 3 and a remainder of 776.
The next digit of our result is 3. 
Result so far: 83.0
The remainder is 776 after subtracting 2553 from 3329.
Take the next digit (3) from the dividend and append it to 776, then repeat: 7763 / 851

Going ahead to step 6:
7763 divided by 851 is 9 with a remainder of 104.
The next digit of our result is 9. 
Result so far: 839.0
Subtract 7659 from 7763 to get 104.
Grab the next digit (7) from the dividend, add it to 104, then carry on: 1047 / 851

Advancing to step 7:
1047 divided by 851 is 1 with a remainder of 196.
Record the quotient 1 as the next digit in the result. 
Result so far: 8391.0
The remainder is 196 after subtracting 851 from 1047.
Grab the next digit (0) from the dividend, add it to 196, then carry on: 1960 / 851

Moving on to step 8:
851 can be fit into 1960 2 times, resulting in a remainder of 258.
Put 2 as the next digit of the answer. 
Result so far: 83912.0
Subtract 1702 from 1960 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 9:
If we divide 2580 by 851, we get 3 and a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 83912.3
If we subtract 2553 from 2580, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 10:
851 goes into 270 0 times with a remainder of 270.
Write down 0 as next digit of the result. 
Result so far: 83912.3
Deduct 0 from 270 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 11:
851 goes into 2700 3 times with a remainder of 147.
Use 3 as the next digit of our solution. 
Result so far: 83912.303
If we take 2553 away from 2700, we end up with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Moving on to step 12:
851 goes into 1470 1 times with a remainder of 619.
Use 1 as the next digit of our solution. 
Result so far: 83912.3031
If we subtract 851 from 1470, we get 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

On to step 13:
If we divide 6190 by 851, we get 7 and a remainder of 233.
Use 7 as the next digit of our solution. 
Result so far: 83912.30317
Subtracting 5957 from 6190 leaves us with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Step 14:
If we divide 2330 by 851, we get 2 and a remainder of 628.
Write down 2 as next digit of the result. 
Result so far: 83912.303172
If we take 1702 away from 2330, we end up with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

On to step 15:
When dividing 6280 by 851, we get 7 with a remainder of 323.
Use 7 as the next digit of our solution. 
Result so far: 83912.3031727
Subtracting 5957 from 6280 leaves us with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

On to step 16:
851 goes into 3230 3 times with a remainder of 677.
Use 3 as the next digit of our solution. 
Result so far: 83912.30317273
The remainder is 677 after subtracting 2553 from 3230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

The final outcome is 83912.30317273, with a leftover of 6.77e-07.
