We look at the division of 70621074 by 851 
Our goal is to divide 70621074 by 851.

Let's proceed to step 1:
851 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 851

Moving on to step 2:
If we divide 70 by 851, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Bring next digit (6) of the dividend behind the 70 and repeat the process: 706 / 851

Advancing to step 3:
851 can be fit into 706 0 times, resulting in a remainder of 706.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 706 to get 706.
Take the next digit (2) from the dividend and append it to 706, then repeat: 7062 / 851

Going ahead to step 4:
851 can be fit into 7062 8 times, resulting in a remainder of 254.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 6808 away from 7062, we end up with 254.
Take the next digit (1) from the dividend and append it to 254, then repeat: 2541 / 851

Going ahead to step 5:
851 can be fit into 2541 2 times, resulting in a remainder of 839.
The next digit of our result is 2. 
Result so far: 82.0
If we take 1702 away from 2541, we end up with 839.
Grab the next digit (0) from the dividend, add it to 839, then carry on: 8390 / 851

Step 6:
The number 851 fits into 8390 9 times, leaving a remainder of 731.
Put 9 as the next digit of the answer. 
Result so far: 829.0
Deduct 7659 from 8390 and we're left with 731.
Take the next digit (7) from the dividend and append it to 731, then repeat: 7317 / 851

Let's proceed to step 7:
If we divide 7317 by 851, we get 8 and a remainder of 509.
Record the quotient 8 as the next digit in the result. 
Result so far: 8298.0
Subtracting 6808 from 7317 leaves us with 509.
Bring next digit (4) of the dividend behind the 509 and repeat the process: 5094 / 851

Step 8:
851 can be fit into 5094 5 times, resulting in a remainder of 839.
Put 5 as the next digit of the answer. 
Result so far: 82985.0
If we subtract 4255 from 5094, we get 839.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8390, and continue the process.

Step 9:
8390 divided by 851 is 9 with a remainder of 731.
The next digit of our result is 9. 
Result so far: 82985.9
If we take 7659 away from 8390, we end up with 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Moving on to step 10:
When dividing 7310 by 851, we get 8 with a remainder of 502.
Use 8 as the next digit of our solution. 
Result so far: 82985.98
Subtracting 6808 from 7310 leaves us with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Moving on to step 11:
If we divide 5020 by 851, we get 5 and a remainder of 765.
The next digit of our result is 5. 
Result so far: 82985.985
Deduct 4255 from 5020 and we're left with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Going ahead to step 12:
7650 divided by 851 is 8 with a remainder of 842.
Record the quotient 8 as the next digit in the result. 
Result so far: 82985.9858
If we take 6808 away from 7650, we end up with 842.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

Advancing to step 13:
The number 851 fits into 8420 9 times, leaving a remainder of 761.
Record the quotient 9 as the next digit in the result. 
Result so far: 82985.98589
Deduct 7659 from 8420 and we're left with 761.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7610, and continue the process.

Let's proceed to step 14:
If we divide 7610 by 851, we get 8 and a remainder of 802.
Record the quotient 8 as the next digit in the result. 
Result so far: 82985.985898
Subtracting 6808 from 7610 leaves us with 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Let's proceed to step 15:
If we divide 8020 by 851, we get 9 and a remainder of 361.
Record the quotient 9 as the next digit in the result. 
Result so far: 82985.9858989
Subtract 7659 from 8020 to get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Going ahead to step 16:
The number 851 fits into 3610 4 times, leaving a remainder of 206.
The next digit of our result is 4. 
Result so far: 82985.98589894
If we subtract 3404 from 3610, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

In conclusion, the division gives 82985.98589894 with a balance of 2.06e-07.
