We look at the division of 21249226 by 5 
Our goal is to divide 21249226 by 5.

Step 1:
If we divide 2 by 5, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 5

On to step 2:
The number 5 fits into 21 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 20 from 21 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 5

Let's proceed to step 3:
5 goes into 12 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtract 10 from 12 to get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 5

Let's proceed to step 4:
24 divided by 5 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 424.0
The remainder is 4 after subtracting 20 from 24.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 5

On to step 5:
When dividing 49 by 5, we get 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 4249.0
Subtract 45 from 49 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 5

Step 6:
The number 5 fits into 42 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 42498.0
The remainder is 2 after subtracting 40 from 42.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 5

Going ahead to step 7:
5 goes into 22 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 424984.0
If we take 20 away from 22, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 5

Moving on to step 8:
When dividing 26 by 5, we get 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 4249845.0
If we subtract 25 from 26, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
If we divide 10 by 5, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 4249845.2
If we take 10 away from 10, 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.

Moving on to step 10:
If we divide 0 by 5, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 4249845.2
Subtract 0 from 0 to 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.

Advancing to step 11:
0 divided by 5 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4249845.2
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.

In conclusion, the division gives 4249845.2 with a balance of 0.0.
