21622852 ÷ 552 
We want to figure out the number of times 21622852 can be divided by 552.

Advancing to step 1:
552 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 552

Moving on to step 2:
When dividing 21 by 552, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 552

Moving on to step 3:
552 can be fit into 216 0 times, resulting in a remainder of 216.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 216, we get 216.
Grab the next digit (2) from the dividend, add it to 216, then carry on: 2162 / 552

Going ahead to step 4:
If we divide 2162 by 552, we get 3 and a remainder of 506.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 1656 from 2162 leaves us with 506.
Take the next digit (2) from the dividend and append it to 506, then repeat: 5062 / 552

Step 5:
If we divide 5062 by 552, we get 9 and a remainder of 94.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtract 4968 from 5062 to get 94.
Grab the next digit (8) from the dividend, add it to 94, then carry on: 948 / 552

Let's proceed to step 6:
If we divide 948 by 552, we get 1 and a remainder of 396.
Write down 1 as next digit of the result. 
Result so far: 391.0
If we subtract 552 from 948, we get 396.
Grab the next digit (5) from the dividend, add it to 396, then carry on: 3965 / 552

Going ahead to step 7:
If we divide 3965 by 552, we get 7 and a remainder of 101.
Write down 7 as next digit of the result. 
Result so far: 3917.0
Deduct 3864 from 3965 and we're left with 101.
Bring next digit (2) of the dividend behind the 101 and repeat the process: 1012 / 552

Going ahead to step 8:
1012 divided by 552 is 1 with a remainder of 460.
Write down 1 as next digit of the result. 
Result so far: 39171.0
Deduct 552 from 1012 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 9:
552 goes into 4600 8 times with a remainder of 184.
Record the quotient 8 as the next digit in the result. 
Result so far: 39171.8
Deduct 4416 from 4600 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 10:
The number 552 fits into 1840 3 times, leaving a remainder of 184.
Record the quotient 3 as the next digit in the result. 
Result so far: 39171.83
If we subtract 1656 from 1840, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 11:
552 goes into 1840 3 times with a remainder of 184.
Use 3 as the next digit of our solution. 
Result so far: 39171.833
Subtract 1656 from 1840 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final result is 39171.833 with a remainder of 0.0184.
