We're dividing 79102421 by 851 
Let's see how many times 851 fits into 79102421.

Going ahead to step 1:
851 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 851

Advancing to step 2:
The number 851 fits into 79 0 times, leaving a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Fetch the next digit (1) from the dividend, attach it to 79 and continue: 791 / 851

Going ahead to step 3:
851 goes into 791 0 times with a remainder of 791.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 791, we get 791.
Fetch the next digit (0) from the dividend, attach it to 791 and continue: 7910 / 851

Step 4:
The number 851 fits into 7910 9 times, leaving a remainder of 251.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 7659 from 7910 leaves us with 251.
Take the next digit (2) from the dividend and append it to 251, then repeat: 2512 / 851

On to step 5:
2512 divided by 851 is 2 with a remainder of 810.
Put 2 as the next digit of the answer. 
Result so far: 92.0
If we subtract 1702 from 2512, we get 810.
Take the next digit (4) from the dividend and append it to 810, then repeat: 8104 / 851

Let's proceed to step 6:
851 goes into 8104 9 times with a remainder of 445.
Write down 9 as next digit of the result. 
Result so far: 929.0
The remainder is 445 after subtracting 7659 from 8104.
Take the next digit (2) from the dividend and append it to 445, then repeat: 4452 / 851

Moving on to step 7:
851 can be fit into 4452 5 times, resulting in a remainder of 197.
Write down 5 as next digit of the result. 
Result so far: 9295.0
If we take 4255 away from 4452, we end up with 197.
Include the next digit (1) from the dividend after 197, then repeat: 1971 / 851

On to step 8:
1971 divided by 851 is 2 with a remainder of 269.
Put 2 as the next digit of the answer. 
Result so far: 92952.0
If we subtract 1702 from 1971, we get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Let's proceed to step 9:
2690 divided by 851 is 3 with a remainder of 137.
Record the quotient 3 as the next digit in the result. 
Result so far: 92952.3
Deduct 2553 from 2690 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Let's proceed to step 10:
851 can be fit into 1370 1 times, resulting in a remainder of 519.
Write down 1 as next digit of the result. 
Result so far: 92952.31
Deduct 851 from 1370 and we're left with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Going ahead to step 11:
851 can be fit into 5190 6 times, resulting in a remainder of 84.
The next digit of our result is 6. 
Result so far: 92952.316
Subtract 5106 from 5190 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 12:
If we divide 840 by 851, we get 0 and a remainder of 840.
Record the quotient 0 as the next digit in the result. 
Result so far: 92952.316
The remainder is 840 after subtracting 0 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Step 13:
851 can be fit into 8400 9 times, resulting in a remainder of 741.
Record the quotient 9 as the next digit in the result. 
Result so far: 92952.31609
If we subtract 7659 from 8400, we get 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

Going ahead to step 14:
7410 divided by 851 is 8 with a remainder of 602.
The next digit of our result is 8. 
Result so far: 92952.316098
If we subtract 6808 from 7410, we get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Going ahead to step 15:
If we divide 6020 by 851, we get 7 and a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 92952.3160987
Deduct 5957 from 6020 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 16:
630 divided by 851 is 0 with a remainder of 630.
Write down 0 as next digit of the result. 
Result so far: 92952.3160987
The remainder is 630 after subtracting 0 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

The quotient of the division is 92952.3160987, and the remainder is 6.3e-07.
