We look at the division of 51944208 by 553 
The aim is to understand the frequency of 553 in 51944208.

Going ahead to step 1:
When dividing 5 by 553, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 553

Moving on to step 2:
The number 553 fits into 51 0 times, leaving a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 553

Let's proceed to step 3:
519 divided by 553 is 0 with a remainder of 519.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 519 and we're left with 519.
Bring next digit (4) of the dividend behind the 519 and repeat the process: 5194 / 553

Moving on to step 4:
553 can be fit into 5194 9 times, resulting in a remainder of 217.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 4977 from 5194 to get 217.
Grab the next digit (4) from the dividend, add it to 217, then carry on: 2174 / 553

On to step 5:
If we divide 2174 by 553, we get 3 and a remainder of 515.
Write down 3 as next digit of the result. 
Result so far: 93.0
If we take 1659 away from 2174, we end up with 515.
Grab the next digit (2) from the dividend, add it to 515, then carry on: 5152 / 553

Step 6:
When dividing 5152 by 553, we get 9 with a remainder of 175.
Write down 9 as next digit of the result. 
Result so far: 939.0
If we take 4977 away from 5152, we end up with 175.
Bring next digit (0) of the dividend behind the 175 and repeat the process: 1750 / 553

Let's proceed to step 7:
If we divide 1750 by 553, we get 3 and a remainder of 91.
The number 3 becomes the next digit in our result. 
Result so far: 9393.0
If we take 1659 away from 1750, we end up with 91.
Grab the next digit (8) from the dividend, add it to 91, then carry on: 918 / 553

Advancing to step 8:
The number 553 fits into 918 1 times, leaving a remainder of 365.
Write down 1 as next digit of the result. 
Result so far: 93931.0
If we take 553 away from 918, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Going ahead to step 9:
553 goes into 3650 6 times with a remainder of 332.
Put 6 as the next digit of the answer. 
Result so far: 93931.6
If we subtract 3318 from 3650, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 10:
The number 553 fits into 3320 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 93931.66
Subtracting 3318 from 3320 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 93931.66 with a remainder of 0.002.
