We look at the division of 79191 by 902 
We're looking to find how many times 902 goes into 79191.

On to step 1:
7 divided by 902 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 902

Moving on to step 2:
The number 902 fits into 79 0 times, leaving a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Bring next digit (1) of the dividend behind the 79 and repeat the process: 791 / 902

Moving on to step 3:
When dividing 791 by 902, we get 0 with a remainder of 791.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 791 leaves us with 791.
Take the next digit (9) from the dividend and append it to 791, then repeat: 7919 / 902

Going ahead to step 4:
When dividing 7919 by 902, we get 8 with a remainder of 703.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 703 after subtracting 7216 from 7919.
Bring next digit (1) of the dividend behind the 703 and repeat the process: 7031 / 902

Step 5:
The number 902 fits into 7031 7 times, leaving a remainder of 717.
The next digit of our result is 7. 
Result so far: 87.0
Deduct 6314 from 7031 and we're left with 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

Going ahead to step 6:
902 goes into 7170 7 times with a remainder of 856.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.7
Deduct 6314 from 7170 and we're left with 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Step 7:
8560 divided by 902 is 9 with a remainder of 442.
Record the quotient 9 as the next digit in the result. 
Result so far: 87.79
Deduct 8118 from 8560 and we're left with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Advancing to step 8:
If we divide 4420 by 902, we get 4 and a remainder of 812.
Use 4 as the next digit of our solution. 
Result so far: 87.794
Deduct 3608 from 4420 and we're left with 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

Advancing to step 9:
8120 divided by 902 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 87.7949
The remainder is 2 after subtracting 8118 from 8120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
902 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 87.7949
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
902 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 87.7949
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 87.7949 and a remainder of 2e-05.
