61515797 ÷ 880 
Our goal is to divide 61515797 by 880.

Advancing to step 1:
880 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 880

Let's proceed to step 2:
880 can be fit into 61 0 times, resulting in a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Bring next digit (5) of the dividend behind the 61 and repeat the process: 615 / 880

On to step 3:
When dividing 615 by 880, we get 0 with a remainder of 615.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 615 leaves us with 615.
Include the next digit (1) from the dividend after 615, then repeat: 6151 / 880

On to step 4:
6151 divided by 880 is 6 with a remainder of 871.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 5280 away from 6151, we end up with 871.
Grab the next digit (5) from the dividend, add it to 871, then carry on: 8715 / 880

Let's proceed to step 5:
The number 880 fits into 8715 9 times, leaving a remainder of 795.
Write down 9 as next digit of the result. 
Result so far: 69.0
If we subtract 7920 from 8715, we get 795.
Bring next digit (7) of the dividend behind the 795 and repeat the process: 7957 / 880

Let's proceed to step 6:
7957 divided by 880 is 9 with a remainder of 37.
The next digit of our result is 9. 
Result so far: 699.0
Subtracting 7920 from 7957 leaves us with 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 880

Step 7:
The number 880 fits into 379 0 times, leaving a remainder of 379.
Record the quotient 0 as the next digit in the result. 
Result so far: 6990.0
If we subtract 0 from 379, we get 379.
Fetch the next digit (7) from the dividend, attach it to 379 and continue: 3797 / 880

Advancing to step 8:
If we divide 3797 by 880, we get 4 and a remainder of 277.
The next digit of our result is 4. 
Result so far: 69904.0
Subtracting 3520 from 3797 leaves us with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Let's proceed to step 9:
When dividing 2770 by 880, we get 3 with a remainder of 130.
Write down 3 as next digit of the result. 
Result so far: 69904.3
If we subtract 2640 from 2770, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
1300 divided by 880 is 1 with a remainder of 420.
Use 1 as the next digit of our solution. 
Result so far: 69904.31
Deduct 880 from 1300 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 11:
4200 divided by 880 is 4 with a remainder of 680.
Record the quotient 4 as the next digit in the result. 
Result so far: 69904.314
The remainder is 680 after subtracting 3520 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

On to step 12:
6800 divided by 880 is 7 with a remainder of 640.
The number 7 becomes the next digit in our result. 
Result so far: 69904.3147
Subtract 6160 from 6800 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 13:
The number 880 fits into 6400 7 times, leaving a remainder of 240.
Put 7 as the next digit of the answer. 
Result so far: 69904.31477
If we subtract 6160 from 6400, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 69904.31477 with a remainder of 0.00024.
