12127385 divided by 558 
The aim is to understand the frequency of 558 in 12127385.

Let's proceed to step 1:
If we divide 1 by 558, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 558

Advancing to step 2:
558 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 558

Moving on to step 3:
The number 558 fits into 121 0 times, leaving a remainder of 121.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 121 after subtracting 0 from 121.
Take the next digit (2) from the dividend and append it to 121, then repeat: 1212 / 558

Moving on to step 4:
558 goes into 1212 2 times with a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1116 from 1212 leaves us with 96.
Include the next digit (7) from the dividend after 96, then repeat: 967 / 558

Let's proceed to step 5:
If we divide 967 by 558, we get 1 and a remainder of 409.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 558 away from 967, we end up with 409.
Bring next digit (3) of the dividend behind the 409 and repeat the process: 4093 / 558

On to step 6:
558 goes into 4093 7 times with a remainder of 187.
Use 7 as the next digit of our solution. 
Result so far: 217.0
Subtracting 3906 from 4093 leaves us with 187.
Take the next digit (8) from the dividend and append it to 187, then repeat: 1878 / 558

Let's proceed to step 7:
If we divide 1878 by 558, we get 3 and a remainder of 204.
Use 3 as the next digit of our solution. 
Result so far: 2173.0
Subtract 1674 from 1878 to get 204.
Fetch the next digit (5) from the dividend, attach it to 204 and continue: 2045 / 558

Advancing to step 8:
If we divide 2045 by 558, we get 3 and a remainder of 371.
The next digit of our result is 3. 
Result so far: 21733.0
If we subtract 1674 from 2045, we get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Step 9:
558 goes into 3710 6 times with a remainder of 362.
The next digit of our result is 6. 
Result so far: 21733.6
Subtract 3348 from 3710 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Going ahead to step 10:
558 can be fit into 3620 6 times, resulting in a remainder of 272.
Write down 6 as next digit of the result. 
Result so far: 21733.66
Subtract 3348 from 3620 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The quotient of the division is 21733.66, and the remainder is 0.272.
