21296408 ÷ 440 
We want to divide 21296408 by 440.

Let's proceed to step 1:
If we divide 2 by 440, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 440

Step 2:
440 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 440

Going ahead to step 3:
If we divide 212 by 440, we get 0 and a remainder of 212.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 212 and we're left with 212.
Take the next digit (9) from the dividend and append it to 212, then repeat: 2129 / 440

Going ahead to step 4:
If we divide 2129 by 440, we get 4 and a remainder of 369.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 1760 from 2129 and we're left with 369.
Grab the next digit (6) from the dividend, add it to 369, then carry on: 3696 / 440

Step 5:
When dividing 3696 by 440, we get 8 with a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtracting 3520 from 3696 leaves us with 176.
Bring next digit (4) of the dividend behind the 176 and repeat the process: 1764 / 440

Step 6:
If we divide 1764 by 440, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 484.0
Deduct 1760 from 1764 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 440

On to step 7:
440 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 4840.0
If we take 0 away from 40, we end up with 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 440

Moving on to step 8:
440 goes into 408 0 times with a remainder of 408.
Record the quotient 0 as the next digit in the result. 
Result so far: 48400.0
The remainder is 408 after subtracting 0 from 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 9:
When dividing 4080 by 440, we get 9 with a remainder of 120.
Record the quotient 9 as the next digit in the result. 
Result so far: 48400.9
If we take 3960 away from 4080, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 10:
440 can be fit into 1200 2 times, resulting in a remainder of 320.
The next digit of our result is 2. 
Result so far: 48400.92
If we subtract 880 from 1200, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 11:
If we divide 3200 by 440, we get 7 and a remainder of 120.
The next digit of our result is 7. 
Result so far: 48400.927
Subtracting 3080 from 3200 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 12:
If we divide 1200 by 440, we get 2 and a remainder of 320.
Record the quotient 2 as the next digit in the result. 
Result so far: 48400.9272
The remainder is 320 after subtracting 880 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 13:
When dividing 3200 by 440, we get 7 with a remainder of 120.
Use 7 as the next digit of our solution. 
Result so far: 48400.92727
Subtracting 3080 from 3200 leaves us with 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 14:
When dividing 1200 by 440, we get 2 with a remainder of 320.
Put 2 as the next digit of the answer. 
Result so far: 48400.927272
If we take 880 away from 1200, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 15:
440 can be fit into 3200 7 times, resulting in a remainder of 120.
Use 7 as the next digit of our solution. 
Result so far: 48400.9272727
The remainder is 120 after subtracting 3080 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 16:
1200 divided by 440 is 2 with a remainder of 320.
Use 2 as the next digit of our solution. 
Result so far: 48400.92727272
Subtract 880 from 1200 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

In conclusion, the division gives 48400.92727272 with a balance of 3.2e-07.
