We're dividing 79315413 by 902 
We want to divide 79315413 by 902.

Going ahead to step 1:
902 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 902

Going ahead to step 2:
902 goes into 79 0 times with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Bring next digit (3) of the dividend behind the 79 and repeat the process: 793 / 902

Advancing to step 3:
If we divide 793 by 902, we get 0 and a remainder of 793.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 793 after subtracting 0 from 793.
Grab the next digit (1) from the dividend, add it to 793, then carry on: 7931 / 902

Let's proceed to step 4:
902 can be fit into 7931 8 times, resulting in a remainder of 715.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 7216 away from 7931, we end up with 715.
Bring next digit (5) of the dividend behind the 715 and repeat the process: 7155 / 902

Moving on to step 5:
The number 902 fits into 7155 7 times, leaving a remainder of 841.
The next digit of our result is 7. 
Result so far: 87.0
Subtract 6314 from 7155 to get 841.
Include the next digit (4) from the dividend after 841, then repeat: 8414 / 902

Step 6:
If we divide 8414 by 902, we get 9 and a remainder of 296.
Put 9 as the next digit of the answer. 
Result so far: 879.0
Subtracting 8118 from 8414 leaves us with 296.
Fetch the next digit (1) from the dividend, attach it to 296 and continue: 2961 / 902

Advancing to step 7:
2961 divided by 902 is 3 with a remainder of 255.
The number 3 becomes the next digit in our result. 
Result so far: 8793.0
Deduct 2706 from 2961 and we're left with 255.
Bring next digit (3) of the dividend behind the 255 and repeat the process: 2553 / 902

Moving on to step 8:
902 goes into 2553 2 times with a remainder of 749.
Use 2 as the next digit of our solution. 
Result so far: 87932.0
Subtracting 1804 from 2553 leaves us with 749.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7490, and continue the process.

On to step 9:
When dividing 7490 by 902, we get 8 with a remainder of 274.
Write down 8 as next digit of the result. 
Result so far: 87932.8
Subtract 7216 from 7490 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Moving on to step 10:
902 can be fit into 2740 3 times, resulting in a remainder of 34.
The next digit of our result is 3. 
Result so far: 87932.83
If we take 2706 away from 2740, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
If we divide 340 by 902, we get 0 and a remainder of 340.
The next digit of our result is 0. 
Result so far: 87932.83
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 12:
The number 902 fits into 3400 3 times, leaving a remainder of 694.
Use 3 as the next digit of our solution. 
Result so far: 87932.8303
If we take 2706 away from 3400, we end up with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

On to step 13:
902 can be fit into 6940 7 times, resulting in a remainder of 626.
Put 7 as the next digit of the answer. 
Result so far: 87932.83037
If we take 6314 away from 6940, we end up with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

On to step 14:
If we divide 6260 by 902, we get 6 and a remainder of 848.
The next digit of our result is 6. 
Result so far: 87932.830376
If we subtract 5412 from 6260, we get 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

Moving on to step 15:
902 goes into 8480 9 times with a remainder of 362.
Write down 9 as next digit of the result. 
Result so far: 87932.8303769
Subtract 8118 from 8480 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Going ahead to step 16:
902 can be fit into 3620 4 times, resulting in a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 87932.83037694
If we subtract 3608 from 3620, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 87932.83037694 with a remainder of 1.2e-08.
