21230462 ÷ 880 
We want to divide 21230462 by 880.

Step 1:
If we divide 2 by 880, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 880

On to step 2:
880 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 880

Moving on to step 3:
The number 880 fits into 212 0 times, leaving a remainder of 212.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 212 and we're left with 212.
Take the next digit (3) from the dividend and append it to 212, then repeat: 2123 / 880

Going ahead to step 4:
If we divide 2123 by 880, we get 2 and a remainder of 363.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1760 from 2123 to get 363.
Fetch the next digit (0) from the dividend, attach it to 363 and continue: 3630 / 880

Advancing to step 5:
880 goes into 3630 4 times with a remainder of 110.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Deduct 3520 from 3630 and we're left with 110.
Fetch the next digit (4) from the dividend, attach it to 110 and continue: 1104 / 880

Step 6:
The number 880 fits into 1104 1 times, leaving a remainder of 224.
Use 1 as the next digit of our solution. 
Result so far: 241.0
The remainder is 224 after subtracting 880 from 1104.
Include the next digit (6) from the dividend after 224, then repeat: 2246 / 880

Going ahead to step 7:
If we divide 2246 by 880, we get 2 and a remainder of 486.
Put 2 as the next digit of the answer. 
Result so far: 2412.0
Subtract 1760 from 2246 to get 486.
Bring next digit (2) of the dividend behind the 486 and repeat the process: 4862 / 880

Moving on to step 8:
4862 divided by 880 is 5 with a remainder of 462.
Record the quotient 5 as the next digit in the result. 
Result so far: 24125.0
Subtracting 4400 from 4862 leaves us with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Step 9:
4620 divided by 880 is 5 with a remainder of 220.
Use 5 as the next digit of our solution. 
Result so far: 24125.5
Subtract 4400 from 4620 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 10:
880 goes into 2200 2 times with a remainder of 440.
Use 2 as the next digit of our solution. 
Result so far: 24125.52
If we take 1760 away from 2200, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 11:
880 can be fit into 4400 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 24125.525
Subtracting 4400 from 4400 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
If we divide 0 by 880, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 24125.525
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
When dividing 0 by 880, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 24125.525
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 24125.525, and the remainder is 0.0.
