Let's divide 12604289 by 880
We want to figure out the number of times 12604289 can be divided by 880.

Let's proceed to step 1:
The number 880 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 880

Advancing to step 2:
12 divided by 880 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 880

Advancing to step 3:
The number 880 fits into 126 0 times, leaving a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 126, we get 126.
Grab the next digit (0) from the dividend, add it to 126, then carry on: 1260 / 880

Advancing to step 4:
The number 880 fits into 1260 1 times, leaving a remainder of 380.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 880 from 1260 to get 380.
Bring next digit (4) of the dividend behind the 380 and repeat the process: 3804 / 880

Step 5:
When dividing 3804 by 880, we get 4 with a remainder of 284.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 284 after subtracting 3520 from 3804.
Append the next digit (2) from the dividend to 284 and continue with: 2842 / 880

Moving on to step 6:
If we divide 2842 by 880, we get 3 and a remainder of 202.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
If we take 2640 away from 2842, we end up with 202.
Grab the next digit (8) from the dividend, add it to 202, then carry on: 2028 / 880

Going ahead to step 7:
If we divide 2028 by 880, we get 2 and a remainder of 268.
Put 2 as the next digit of the answer. 
Result so far: 1432.0
Subtracting 1760 from 2028 leaves us with 268.
Fetch the next digit (9) from the dividend, attach it to 268 and continue: 2689 / 880

Going ahead to step 8:
When dividing 2689 by 880, we get 3 with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 14323.0
If we subtract 2640 from 2689, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 9:
880 can be fit into 490 0 times, resulting in a remainder of 490.
Record the quotient 0 as the next digit in the result. 
Result so far: 14323.0
Deduct 0 from 490 and we're left 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.

Step 10:
The number 880 fits into 4900 5 times, leaving a remainder of 500.
The next digit of our result is 5. 
Result so far: 14323.05
If we take 4400 away from 4900, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 11:
5000 divided by 880 is 5 with a remainder of 600.
Record the quotient 5 as the next digit in the result. 
Result so far: 14323.055
Subtract 4400 from 5000 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 14323.055 with a remainder of 0.06.
