21234568 ÷ 792 
We're looking to find how many times 792 goes into 21234568.

Step 1:
2 divided by 792 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 792

Going ahead to step 2:
If we divide 21 by 792, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 792

Going ahead to step 3:
When dividing 212 by 792, we get 0 with a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 212 and we're left with 212.
Bring next digit (3) of the dividend behind the 212 and repeat the process: 2123 / 792

Going ahead to step 4:
792 can be fit into 2123 2 times, resulting in a remainder of 539.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1584 from 2123, we get 539.
Append the next digit (4) from the dividend to 539 and continue with: 5394 / 792

Step 5:
If we divide 5394 by 792, we get 6 and a remainder of 642.
Put 6 as the next digit of the answer. 
Result so far: 26.0
The remainder is 642 after subtracting 4752 from 5394.
Fetch the next digit (5) from the dividend, attach it to 642 and continue: 6425 / 792

Step 6:
If we divide 6425 by 792, we get 8 and a remainder of 89.
The next digit of our result is 8. 
Result so far: 268.0
Subtracting 6336 from 6425 leaves us with 89.
Fetch the next digit (6) from the dividend, attach it to 89 and continue: 896 / 792

Let's proceed to step 7:
If we divide 896 by 792, we get 1 and a remainder of 104.
Write down 1 as next digit of the result. 
Result so far: 2681.0
The remainder is 104 after subtracting 792 from 896.
Take the next digit (8) from the dividend and append it to 104, then repeat: 1048 / 792

Moving on to step 8:
The number 792 fits into 1048 1 times, leaving a remainder of 256.
The number 1 becomes the next digit in our result. 
Result so far: 26811.0
Deduct 792 from 1048 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 9:
2560 divided by 792 is 3 with a remainder of 184.
Record the quotient 3 as the next digit in the result. 
Result so far: 26811.3
If we subtract 2376 from 2560, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 10:
1840 divided by 792 is 2 with a remainder of 256.
The number 2 becomes the next digit in our result. 
Result so far: 26811.32
If we take 1584 away from 1840, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 11:
2560 divided by 792 is 3 with a remainder of 184.
The number 3 becomes the next digit in our result. 
Result so far: 26811.323
The remainder is 184 after subtracting 2376 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 12:
If we divide 1840 by 792, we get 2 and a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 26811.3232
If we subtract 1584 from 1840, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 13:
792 goes into 2560 3 times with a remainder of 184.
Write down 3 as next digit of the result. 
Result so far: 26811.32323
If we subtract 2376 from 2560, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 14:
If we divide 1840 by 792, we get 2 and a remainder of 256.
Use 2 as the next digit of our solution. 
Result so far: 26811.323232
If we take 1584 away from 1840, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 15:
If we divide 2560 by 792, we get 3 and a remainder of 184.
Put 3 as the next digit of the answer. 
Result so far: 26811.3232323
Subtracting 2376 from 2560 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 16:
If we divide 1840 by 792, we get 2 and a remainder of 256.
The number 2 becomes the next digit in our result. 
Result so far: 26811.32323232
Subtracting 1584 from 1840 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

After the division, we end up with 26811.32323232 and a remainder of 2.56e-07.
