We're dividing 615580 by 78 
We want to divide 615580 by 78.

On to step 1:
6 divided by 78 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 78

Advancing to step 2:
78 goes into 61 0 times with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Grab the next digit (5) from the dividend, add it to 61, then carry on: 615 / 78

Step 3:
If we divide 615 by 78, we get 7 and a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 69 after subtracting 546 from 615.
Grab the next digit (5) from the dividend, add it to 69, then carry on: 695 / 78

On to step 4:
78 goes into 695 8 times with a remainder of 71.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Deduct 624 from 695 and we're left with 71.
Bring next digit (8) of the dividend behind the 71 and repeat the process: 718 / 78

Advancing to step 5:
When dividing 718 by 78, we get 9 with a remainder of 16.
The next digit of our result is 9. 
Result so far: 789.0
Subtract 702 from 718 to get 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 78

Step 6:
The number 78 fits into 160 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 7892.0
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
78 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 7892.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
400 divided by 78 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 7892.05
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
When dividing 100 by 78, we get 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 7892.051
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
The number 78 fits into 220 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 7892.0512
Subtract 156 from 220 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 11:
When dividing 640 by 78, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 7892.05128
Deduct 624 from 640 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
78 goes into 160 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 7892.051282
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
78 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 7892.051282
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
400 divided by 78 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 7892.05128205
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 7892.05128205, and the remainder is 1e-08.
