We're dividing 21108461 by 552 
We want to figure out the number of times 21108461 can be divided by 552.

Going ahead to step 1:
If we divide 2 by 552, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 552

Step 2:
552 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 552

On to step 3:
When dividing 211 by 552, we get 0 with a remainder of 211.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 211, we end up with 211.
Take the next digit (0) from the dividend and append it to 211, then repeat: 2110 / 552

On to step 4:
552 can be fit into 2110 3 times, resulting in a remainder of 454.
The next digit of our result is 3. 
Result so far: 3.0
If we take 1656 away from 2110, we end up with 454.
Fetch the next digit (8) from the dividend, attach it to 454 and continue: 4548 / 552

Advancing to step 5:
The number 552 fits into 4548 8 times, leaving a remainder of 132.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
The remainder is 132 after subtracting 4416 from 4548.
Bring next digit (4) of the dividend behind the 132 and repeat the process: 1324 / 552

Let's proceed to step 6:
If we divide 1324 by 552, we get 2 and a remainder of 220.
The number 2 becomes the next digit in our result. 
Result so far: 382.0
The remainder is 220 after subtracting 1104 from 1324.
Bring next digit (6) of the dividend behind the 220 and repeat the process: 2206 / 552

Going ahead to step 7:
If we divide 2206 by 552, we get 3 and a remainder of 550.
Use 3 as the next digit of our solution. 
Result so far: 3823.0
If we take 1656 away from 2206, we end up with 550.
Include the next digit (1) from the dividend after 550, then repeat: 5501 / 552

Step 8:
When dividing 5501 by 552, we get 9 with a remainder of 533.
Use 9 as the next digit of our solution. 
Result so far: 38239.0
Subtracting 4968 from 5501 leaves us with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Moving on to step 9:
552 goes into 5330 9 times with a remainder of 362.
Write down 9 as next digit of the result. 
Result so far: 38239.9
If we take 4968 away from 5330, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

On to step 10:
When dividing 3620 by 552, we get 6 with a remainder of 308.
Use 6 as the next digit of our solution. 
Result so far: 38239.96
If we subtract 3312 from 3620, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 11:
If we divide 3080 by 552, we get 5 and a remainder of 320.
Put 5 as the next digit of the answer. 
Result so far: 38239.965
Subtract 2760 from 3080 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.

Moving on to step 12:
If we divide 3200 by 552, we get 5 and a remainder of 440.
Put 5 as the next digit of the answer. 
Result so far: 38239.9655
Deduct 2760 from 3200 and we're left 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.

The final result is 38239.9655 with a remainder of 0.0044.
