We look at the division of 30809819 by 552 
The aim is to understand the frequency of 552 in 30809819.

On to step 1:
If we divide 3 by 552, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 552

Let's proceed to step 2:
If we divide 30 by 552, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 552

Advancing to step 3:
552 goes into 308 0 times with a remainder of 308.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 308 and we're left with 308.
Include the next digit (0) from the dividend after 308, then repeat: 3080 / 552

Let's proceed to step 4:
When dividing 3080 by 552, we get 5 with a remainder of 320.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 2760 from 3080 to get 320.
Grab the next digit (9) from the dividend, add it to 320, then carry on: 3209 / 552

Advancing to step 5:
3209 divided by 552 is 5 with a remainder of 449.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
If we subtract 2760 from 3209, we get 449.
Append the next digit (8) from the dividend to 449 and continue with: 4498 / 552

Step 6:
If we divide 4498 by 552, we get 8 and a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 558.0
If we take 4416 away from 4498, we end up with 82.
Take the next digit (1) from the dividend and append it to 82, then repeat: 821 / 552

Going ahead to step 7:
When dividing 821 by 552, we get 1 with a remainder of 269.
Write down 1 as next digit of the result. 
Result so far: 5581.0
Deduct 552 from 821 and we're left with 269.
Fetch the next digit (9) from the dividend, attach it to 269 and continue: 2699 / 552

Going ahead to step 8:
552 can be fit into 2699 4 times, resulting in a remainder of 491.
Put 4 as the next digit of the answer. 
Result so far: 55814.0
If we subtract 2208 from 2699, we get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Advancing to step 9:
When dividing 4910 by 552, we get 8 with a remainder of 494.
Put 8 as the next digit of the answer. 
Result so far: 55814.8
If we take 4416 away from 4910, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

On to step 10:
552 can be fit into 4940 8 times, resulting in a remainder of 524.
Record the quotient 8 as the next digit in the result. 
Result so far: 55814.88
The remainder is 524 after subtracting 4416 from 4940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

The quotient of the division is 55814.88, and the remainder is 0.524.
