We're dividing 21315270 by 44 
Our goal is to divide 21315270 by 44.

Step 1:
When dividing 2 by 44, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
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 / 44

Moving on to step 2:
21 divided by 44 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 44

Let's proceed to step 3:
If we divide 213 by 44, we get 4 and a remainder of 37.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 176 from 213, we get 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 44

Moving on to step 4:
371 divided by 44 is 8 with a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtracting 352 from 371 leaves us with 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 44

Advancing to step 5:
The number 44 fits into 195 4 times, leaving a remainder of 19.
The next digit of our result is 4. 
Result so far: 484.0
The remainder is 19 after subtracting 176 from 195.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 44

Going ahead to step 6:
44 goes into 192 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 4844.0
If we take 176 away from 192, we end up with 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 44

Let's proceed to step 7:
44 goes into 167 3 times with a remainder of 35.
The next digit of our result is 3. 
Result so far: 48443.0
Deduct 132 from 167 and we're left with 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 44

Moving on to step 8:
44 goes into 350 7 times with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 484437.0
Deduct 308 from 350 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
The number 44 fits into 420 9 times, leaving a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 484437.9
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
44 can be fit into 240 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 484437.95
Subtracting 220 from 240 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
If we divide 200 by 44, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 484437.954
If we take 176 away from 200, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
240 divided by 44 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 484437.9545
Subtract 220 from 240 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
200 divided by 44 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 484437.95454
Deduct 176 from 200 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 14:
44 goes into 240 5 times with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 484437.954545
If we subtract 220 from 240, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 15:
44 can be fit into 200 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 484437.9545454
Subtract 176 from 200 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 16:
240 divided by 44 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 484437.95454545
If we take 220 away from 240, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 484437.95454545 and a remainder of 2e-08.
