21126085 ÷ 552 
Our goal is to divide 21126085 by 552.

Going ahead to step 1:
552 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 552

Advancing to step 2:
The number 552 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 552

Step 3:
The number 552 fits into 211 0 times, leaving a remainder of 211.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 211, we end up with 211.
Include the next digit (2) from the dividend after 211, then repeat: 2112 / 552

On to step 4:
When dividing 2112 by 552, we get 3 with a remainder of 456.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 1656 from 2112 leaves us with 456.
Include the next digit (6) from the dividend after 456, then repeat: 4566 / 552

Step 5:
552 can be fit into 4566 8 times, resulting in a remainder of 150.
The next digit of our result is 8. 
Result so far: 38.0
Deduct 4416 from 4566 and we're left with 150.
Fetch the next digit (0) from the dividend, attach it to 150 and continue: 1500 / 552

Let's proceed to step 6:
If we divide 1500 by 552, we get 2 and a remainder of 396.
Record the quotient 2 as the next digit in the result. 
Result so far: 382.0
The remainder is 396 after subtracting 1104 from 1500.
Append the next digit (8) from the dividend to 396 and continue with: 3968 / 552

Moving on to step 7:
552 goes into 3968 7 times with a remainder of 104.
The number 7 becomes the next digit in our result. 
Result so far: 3827.0
If we subtract 3864 from 3968, we get 104.
Fetch the next digit (5) from the dividend, attach it to 104 and continue: 1045 / 552

On to step 8:
552 goes into 1045 1 times with a remainder of 493.
Record the quotient 1 as the next digit in the result. 
Result so far: 38271.0
The remainder is 493 after subtracting 552 from 1045.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Moving on to step 9:
The number 552 fits into 4930 8 times, leaving a remainder of 514.
Put 8 as the next digit of the answer. 
Result so far: 38271.8
Subtracting 4416 from 4930 leaves us with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Going ahead to step 10:
The number 552 fits into 5140 9 times, leaving a remainder of 172.
Write down 9 as next digit of the result. 
Result so far: 38271.89
Subtract 4968 from 5140 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 11:
If we divide 1720 by 552, we get 3 and a remainder of 64.
Record the quotient 3 as the next digit in the result. 
Result so far: 38271.893
Subtract 1656 from 1720 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
When dividing 640 by 552, we get 1 with a remainder of 88.
Record the quotient 1 as the next digit in the result. 
Result so far: 38271.8931
Deduct 552 from 640 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 13:
If we divide 880 by 552, we get 1 and a remainder of 328.
Put 1 as the next digit of the answer. 
Result so far: 38271.89311
Subtract 552 from 880 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Our division results in 38271.89311 with a remaining 0.000328.
