We're dividing 79213988 by 874 
Let's see how many times 874 fits into 79213988.

Advancing to step 1:
If we divide 7 by 874, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 874

On to step 2:
874 can be fit into 79 0 times, resulting in a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Include the next digit (2) from the dividend after 79, then repeat: 792 / 874

On to step 3:
When dividing 792 by 874, we get 0 with a remainder of 792.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 792 leaves us with 792.
Append the next digit (1) from the dividend to 792 and continue with: 7921 / 874

Moving on to step 4:
874 goes into 7921 9 times with a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 7866 from 7921, we get 55.
Grab the next digit (3) from the dividend, add it to 55, then carry on: 553 / 874

On to step 5:
When dividing 553 by 874, we get 0 with a remainder of 553.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Subtract 0 from 553 to get 553.
Bring next digit (9) of the dividend behind the 553 and repeat the process: 5539 / 874

Going ahead to step 6:
874 can be fit into 5539 6 times, resulting in a remainder of 295.
Use 6 as the next digit of our solution. 
Result so far: 906.0
If we take 5244 away from 5539, we end up with 295.
Grab the next digit (8) from the dividend, add it to 295, then carry on: 2958 / 874

On to step 7:
874 can be fit into 2958 3 times, resulting in a remainder of 336.
Write down 3 as next digit of the result. 
Result so far: 9063.0
Subtract 2622 from 2958 to get 336.
Include the next digit (8) from the dividend after 336, then repeat: 3368 / 874

Advancing to step 8:
874 can be fit into 3368 3 times, resulting in a remainder of 746.
The next digit of our result is 3. 
Result so far: 90633.0
Subtract 2622 from 3368 to get 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Let's proceed to step 9:
When dividing 7460 by 874, we get 8 with a remainder of 468.
The next digit of our result is 8. 
Result so far: 90633.8
The remainder is 468 after subtracting 6992 from 7460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Moving on to step 10:
4680 divided by 874 is 5 with a remainder of 310.
Record the quotient 5 as the next digit in the result. 
Result so far: 90633.85
If we subtract 4370 from 4680, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 11:
874 can be fit into 3100 3 times, resulting in a remainder of 478.
The number 3 becomes the next digit in our result. 
Result so far: 90633.853
Subtracting 2622 from 3100 leaves us with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Step 12:
874 can be fit into 4780 5 times, resulting in a remainder of 410.
The next digit of our result is 5. 
Result so far: 90633.8535
Subtracting 4370 from 4780 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 13:
4100 divided by 874 is 4 with a remainder of 604.
The number 4 becomes the next digit in our result. 
Result so far: 90633.85354
Subtract 3496 from 4100 to get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Step 14:
When dividing 6040 by 874, we get 6 with a remainder of 796.
The number 6 becomes the next digit in our result. 
Result so far: 90633.853546
If we take 5244 away from 6040, we end up with 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Let's proceed to step 15:
874 can be fit into 7960 9 times, resulting in a remainder of 94.
Use 9 as the next digit of our solution. 
Result so far: 90633.8535469
If we take 7866 away from 7960, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 16:
When dividing 940 by 874, we get 1 with a remainder of 66.
The number 1 becomes the next digit in our result. 
Result so far: 90633.85354691
Deduct 874 from 940 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 90633.85354691, with a leftover of 6.6e-08.
