We look at the division of 51372396 by 558 
The aim is to understand the frequency of 558 in 51372396.

Step 1:
558 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 558

Let's proceed to step 2:
When dividing 51 by 558, we get 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 558

Moving on to step 3:
558 goes into 513 0 times with a remainder of 513.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 513, we get 513.
Fetch the next digit (7) from the dividend, attach it to 513 and continue: 5137 / 558

Advancing to step 4:
558 goes into 5137 9 times with a remainder of 115.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 5022 from 5137, we get 115.
Grab the next digit (2) from the dividend, add it to 115, then carry on: 1152 / 558

Let's proceed to step 5:
The number 558 fits into 1152 2 times, leaving a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 92.0
The remainder is 36 after subtracting 1116 from 1152.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 558

Going ahead to step 6:
The number 558 fits into 363 0 times, leaving a remainder of 363.
Put 0 as the next digit of the answer. 
Result so far: 920.0
The remainder is 363 after subtracting 0 from 363.
Grab the next digit (9) from the dividend, add it to 363, then carry on: 3639 / 558

On to step 7:
3639 divided by 558 is 6 with a remainder of 291.
Record the quotient 6 as the next digit in the result. 
Result so far: 9206.0
Subtract 3348 from 3639 to get 291.
Include the next digit (6) from the dividend after 291, then repeat: 2916 / 558

Moving on to step 8:
558 can be fit into 2916 5 times, resulting in a remainder of 126.
Write down 5 as next digit of the result. 
Result so far: 92065.0
Deduct 2790 from 2916 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 9:
1260 divided by 558 is 2 with a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 92065.2
Subtracting 1116 from 1260 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 10:
558 can be fit into 1440 2 times, resulting in a remainder of 324.
Write down 2 as next digit of the result. 
Result so far: 92065.22
If we subtract 1116 from 1440, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

In conclusion, the division gives 92065.22 with a balance of 0.324.
