Let's divide 7981122 by 851
Our goal is to divide 7981122 by 851.

On to step 1:
The number 851 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 851

Moving on to step 2:
If we divide 79 by 851, we get 0 and a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Grab the next digit (8) from the dividend, add it to 79, then carry on: 798 / 851

On to step 3:
If we divide 798 by 851, we get 0 and a remainder of 798.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 798 leaves us with 798.
Grab the next digit (1) from the dividend, add it to 798, then carry on: 7981 / 851

Moving on to step 4:
7981 divided by 851 is 9 with a remainder of 322.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 322 after subtracting 7659 from 7981.
Include the next digit (1) from the dividend after 322, then repeat: 3221 / 851

Advancing to step 5:
When dividing 3221 by 851, we get 3 with a remainder of 668.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Deduct 2553 from 3221 and we're left with 668.
Append the next digit (2) from the dividend to 668 and continue with: 6682 / 851

Let's proceed to step 6:
6682 divided by 851 is 7 with a remainder of 725.
The number 7 becomes the next digit in our result. 
Result so far: 937.0
If we take 5957 away from 6682, we end up with 725.
Fetch the next digit (2) from the dividend, attach it to 725 and continue: 7252 / 851

Going ahead to step 7:
The number 851 fits into 7252 8 times, leaving a remainder of 444.
Write down 8 as next digit of the result. 
Result so far: 9378.0
If we subtract 6808 from 7252, we get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 8:
The number 851 fits into 4440 5 times, leaving a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 9378.5
The remainder is 185 after subtracting 4255 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 9:
If we divide 1850 by 851, we get 2 and a remainder of 148.
Use 2 as the next digit of our solution. 
Result so far: 9378.52
Subtracting 1702 from 1850 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 10:
851 goes into 1480 1 times with a remainder of 629.
Write down 1 as next digit of the result. 
Result so far: 9378.521
Subtracting 851 from 1480 leaves us with 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Going ahead to step 11:
If we divide 6290 by 851, we get 7 and a remainder of 333.
The number 7 becomes the next digit in our result. 
Result so far: 9378.5217
If we subtract 5957 from 6290, we get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Going ahead to step 12:
If we divide 3330 by 851, we get 3 and a remainder of 777.
The next digit of our result is 3. 
Result so far: 9378.52173
The remainder is 777 after subtracting 2553 from 3330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Let's proceed to step 13:
When dividing 7770 by 851, we get 9 with a remainder of 111.
Record the quotient 9 as the next digit in the result. 
Result so far: 9378.521739
The remainder is 111 after subtracting 7659 from 7770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 14:
If we divide 1110 by 851, we get 1 and a remainder of 259.
Put 1 as the next digit of the answer. 
Result so far: 9378.5217391
Deduct 851 from 1110 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Let's proceed to step 15:
851 goes into 2590 3 times with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 9378.52173913
If we take 2553 away from 2590, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final result is 9378.52173913 with a remainder of 3.7e-08.
