We're dividing 79385912 by 615 
Let's see how many times 615 fits into 79385912.

Advancing to step 1:
The number 615 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
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 / 615

Step 2:
The number 615 fits into 79 0 times, leaving a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Take the next digit (3) from the dividend and append it to 79, then repeat: 793 / 615

Moving on to step 3:
615 can be fit into 793 1 times, resulting in a remainder of 178.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 615 from 793, we get 178.
Take the next digit (8) from the dividend and append it to 178, then repeat: 1788 / 615

Moving on to step 4:
If we divide 1788 by 615, we get 2 and a remainder of 558.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 1230 away from 1788, we end up with 558.
Include the next digit (5) from the dividend after 558, then repeat: 5585 / 615

On to step 5:
When dividing 5585 by 615, we get 9 with a remainder of 50.
Use 9 as the next digit of our solution. 
Result so far: 129.0
If we take 5535 away from 5585, we end up with 50.
Grab the next digit (9) from the dividend, add it to 50, then carry on: 509 / 615

Advancing to step 6:
615 goes into 509 0 times with a remainder of 509.
The next digit of our result is 0. 
Result so far: 1290.0
Subtract 0 from 509 to get 509.
Take the next digit (1) from the dividend and append it to 509, then repeat: 5091 / 615

Moving on to step 7:
If we divide 5091 by 615, we get 8 and a remainder of 171.
Use 8 as the next digit of our solution. 
Result so far: 12908.0
Subtracting 4920 from 5091 leaves us with 171.
Grab the next digit (2) from the dividend, add it to 171, then carry on: 1712 / 615

On to step 8:
If we divide 1712 by 615, we get 2 and a remainder of 482.
Write down 2 as next digit of the result. 
Result so far: 129082.0
Subtract 1230 from 1712 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

On to step 9:
The number 615 fits into 4820 7 times, leaving a remainder of 515.
Record the quotient 7 as the next digit in the result. 
Result so far: 129082.7
Subtracting 4305 from 4820 leaves us with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Let's proceed to step 10:
When dividing 5150 by 615, we get 8 with a remainder of 230.
Put 8 as the next digit of the answer. 
Result so far: 129082.78
The remainder is 230 after subtracting 4920 from 5150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 11:
2300 divided by 615 is 3 with a remainder of 455.
Use 3 as the next digit of our solution. 
Result so far: 129082.783
Subtracting 1845 from 2300 leaves us with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Step 12:
4550 divided by 615 is 7 with a remainder of 245.
Write down 7 as next digit of the result. 
Result so far: 129082.7837
Subtract 4305 from 4550 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 13:
If we divide 2450 by 615, we get 3 and a remainder of 605.
Write down 3 as next digit of the result. 
Result so far: 129082.78373
If we subtract 1845 from 2450, we get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Going ahead to step 14:
615 can be fit into 6050 9 times, resulting in a remainder of 515.
Write down 9 as next digit of the result. 
Result so far: 129082.783739
Subtract 5535 from 6050 to get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Let's proceed to step 15:
When dividing 5150 by 615, we get 8 with a remainder of 230.
Put 8 as the next digit of the answer. 
Result so far: 129082.7837398
Subtract 4920 from 5150 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 16:
The number 615 fits into 2300 3 times, leaving a remainder of 455.
Use 3 as the next digit of our solution. 
Result so far: 129082.78373983
Subtract 1845 from 2300 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Our division results in 129082.78373983 with a remaining 4.55e-07.
