We divide 79391380 by 615
We want to figure out the number of times 79391380 can be divided by 615.

Going ahead to step 1:
615 goes into 7 0 times with 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.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 615

Moving on to step 2:
79 divided by 615 is 0 with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Fetch the next digit (3) from the dividend, attach it to 79 and continue: 793 / 615

Step 3:
If we divide 793 by 615, we get 1 and a remainder of 178.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 615 from 793, we get 178.
Bring next digit (9) of the dividend behind the 178 and repeat the process: 1789 / 615

On to step 4:
When dividing 1789 by 615, we get 2 with a remainder of 559.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 559 after subtracting 1230 from 1789.
Grab the next digit (1) from the dividend, add it to 559, then carry on: 5591 / 615

On to step 5:
615 can be fit into 5591 9 times, resulting in a remainder of 56.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
The remainder is 56 after subtracting 5535 from 5591.
Append the next digit (3) from the dividend to 56 and continue with: 563 / 615

On to step 6:
If we divide 563 by 615, we get 0 and a remainder of 563.
The next digit of our result is 0. 
Result so far: 1290.0
If we subtract 0 from 563, we get 563.
Take the next digit (8) from the dividend and append it to 563, then repeat: 5638 / 615

Going ahead to step 7:
If we divide 5638 by 615, we get 9 and a remainder of 103.
Write down 9 as next digit of the result. 
Result so far: 12909.0
Subtracting 5535 from 5638 leaves us with 103.
Take the next digit (0) from the dividend and append it to 103, then repeat: 1030 / 615

Going ahead to step 8:
If we divide 1030 by 615, we get 1 and a remainder of 415.
Write down 1 as next digit of the result. 
Result so far: 129091.0
If we take 615 away from 1030, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Step 9:
If we divide 4150 by 615, we get 6 and a remainder of 460.
Use 6 as the next digit of our solution. 
Result so far: 129091.6
The remainder is 460 after subtracting 3690 from 4150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 10:
4600 divided by 615 is 7 with a remainder of 295.
The number 7 becomes the next digit in our result. 
Result so far: 129091.67
If we subtract 4305 from 4600, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 11:
If we divide 2950 by 615, we get 4 and a remainder of 490.
The number 4 becomes the next digit in our result. 
Result so far: 129091.674
Subtracting 2460 from 2950 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 12:
The number 615 fits into 4900 7 times, leaving a remainder of 595.
Use 7 as the next digit of our solution. 
Result so far: 129091.6747
If we take 4305 away from 4900, we end up with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Step 13:
The number 615 fits into 5950 9 times, leaving a remainder of 415.
Put 9 as the next digit of the answer. 
Result so far: 129091.67479
Subtract 5535 from 5950 to get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Moving on to step 14:
4150 divided by 615 is 6 with a remainder of 460.
The next digit of our result is 6. 
Result so far: 129091.674796
Deduct 3690 from 4150 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 15:
If we divide 4600 by 615, we get 7 and a remainder of 295.
The number 7 becomes the next digit in our result. 
Result so far: 129091.6747967
Deduct 4305 from 4600 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 16:
When dividing 2950 by 615, we get 4 with a remainder of 490.
The next digit of our result is 4. 
Result so far: 129091.67479674
If we take 2460 away from 2950, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

In conclusion, the division gives 129091.67479674 with a balance of 4.9e-07.
