78080580 ÷ 610 
We want to figure out the number of times 78080580 can be divided by 610.

Advancing to step 1:
610 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.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 610

Going ahead to step 2:
When dividing 78 by 610, we get 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (0) from the dividend, add it to 78, then carry on: 780 / 610

Advancing to step 3:
610 can be fit into 780 1 times, resulting in a remainder of 170.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 610 from 780, we get 170.
Append the next digit (8) from the dividend to 170 and continue with: 1708 / 610

On to step 4:
If we divide 1708 by 610, we get 2 and a remainder of 488.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 1220 from 1708 leaves us with 488.
Include the next digit (0) from the dividend after 488, then repeat: 4880 / 610

Let's proceed to step 5:
The number 610 fits into 4880 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 128.0
Deduct 4880 from 4880 and we're left with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 610

Let's proceed to step 6:
610 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 1280.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 610

Step 7:
610 goes into 58 0 times with a remainder of 58.
The next digit of our result is 0. 
Result so far: 12800.0
Subtract 0 from 58 to get 58.
Include the next digit (0) from the dividend after 58, then repeat: 580 / 610

Moving on to step 8:
The number 610 fits into 580 0 times, leaving a remainder of 580.
Put 0 as the next digit of the answer. 
Result so far: 128000.0
If we take 0 away from 580, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 9:
When dividing 5800 by 610, we get 9 with a remainder of 310.
The next digit of our result is 9. 
Result so far: 128000.9
Deduct 5490 from 5800 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 10:
3100 divided by 610 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 128000.95
Subtracting 3050 from 3100 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
When dividing 500 by 610, we get 0 with a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 128000.95
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 12:
5000 divided by 610 is 8 with a remainder of 120.
The next digit of our result is 8. 
Result so far: 128000.9508
If we subtract 4880 from 5000, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 13:
610 goes into 1200 1 times with a remainder of 590.
The number 1 becomes the next digit in our result. 
Result so far: 128000.95081
If we subtract 610 from 1200, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 14:
610 goes into 5900 9 times with a remainder of 410.
The number 9 becomes the next digit in our result. 
Result so far: 128000.950819
Deduct 5490 from 5900 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 15:
If we divide 4100 by 610, we get 6 and a remainder of 440.
Put 6 as the next digit of the answer. 
Result so far: 128000.9508196
Subtract 3660 from 4100 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 16:
610 goes into 4400 7 times with a remainder of 130.
Put 7 as the next digit of the answer. 
Result so far: 128000.95081967
Deduct 4270 from 4400 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

After the division, we end up with 128000.95081967 and a remainder of 1.3e-07.
