21364239 divided by 552 
Our goal is to divide 21364239 by 552.

Moving on to step 1:
The number 552 fits into 2 0 times, leaving 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:
When dividing 21 by 552, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 552

Step 3:
552 can be fit into 213 0 times, resulting in a remainder of 213.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 213 after subtracting 0 from 213.
Append the next digit (6) from the dividend to 213 and continue with: 2136 / 552

Going ahead to step 4:
The number 552 fits into 2136 3 times, leaving a remainder of 480.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 1656 from 2136 and we're left with 480.
Include the next digit (4) from the dividend after 480, then repeat: 4804 / 552

Let's proceed to step 5:
552 goes into 4804 8 times with a remainder of 388.
The next digit of our result is 8. 
Result so far: 38.0
Deduct 4416 from 4804 and we're left with 388.
Append the next digit (2) from the dividend to 388 and continue with: 3882 / 552

Going ahead to step 6:
If we divide 3882 by 552, we get 7 and a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 387.0
Deduct 3864 from 3882 and we're left with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 552

Going ahead to step 7:
552 can be fit into 183 0 times, resulting in a remainder of 183.
The number 0 becomes the next digit in our result. 
Result so far: 3870.0
The remainder is 183 after subtracting 0 from 183.
Append the next digit (9) from the dividend to 183 and continue with: 1839 / 552

Going ahead to step 8:
1839 divided by 552 is 3 with a remainder of 183.
The next digit of our result is 3. 
Result so far: 38703.0
Subtracting 1656 from 1839 leaves us with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 9:
If we divide 1830 by 552, we get 3 and a remainder of 174.
Use 3 as the next digit of our solution. 
Result so far: 38703.3
Deduct 1656 from 1830 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 10:
The number 552 fits into 1740 3 times, leaving a remainder of 84.
Record the quotient 3 as the next digit in the result. 
Result so far: 38703.33
If we take 1656 away from 1740, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Our division results in 38703.33 with a remaining 0.084.
