We look at the division of 30627518 by 558 
The aim is to understand the frequency of 558 in 30627518.

On to step 1:
558 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 558

Step 2:
The number 558 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 558

Step 3:
The number 558 fits into 306 0 times, leaving a remainder of 306.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 306 leaves us with 306.
Fetch the next digit (2) from the dividend, attach it to 306 and continue: 3062 / 558

Step 4:
3062 divided by 558 is 5 with a remainder of 272.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 2790 from 3062, we get 272.
Append the next digit (7) from the dividend to 272 and continue with: 2727 / 558

Going ahead to step 5:
The number 558 fits into 2727 4 times, leaving a remainder of 495.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
If we subtract 2232 from 2727, we get 495.
Fetch the next digit (5) from the dividend, attach it to 495 and continue: 4955 / 558

Let's proceed to step 6:
When dividing 4955 by 558, we get 8 with a remainder of 491.
Use 8 as the next digit of our solution. 
Result so far: 548.0
If we take 4464 away from 4955, we end up with 491.
Fetch the next digit (1) from the dividend, attach it to 491 and continue: 4911 / 558

Moving on to step 7:
If we divide 4911 by 558, we get 8 and a remainder of 447.
Record the quotient 8 as the next digit in the result. 
Result so far: 5488.0
The remainder is 447 after subtracting 4464 from 4911.
Fetch the next digit (8) from the dividend, attach it to 447 and continue: 4478 / 558

Let's proceed to step 8:
558 goes into 4478 8 times with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 54888.0
Deduct 4464 from 4478 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
140 divided by 558 is 0 with a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 54888.0
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 10:
The number 558 fits into 1400 2 times, leaving a remainder of 284.
The next digit of our result is 2. 
Result so far: 54888.02
Deduct 1116 from 1400 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 11:
The number 558 fits into 2840 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 54888.025
If we subtract 2790 from 2840, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
When dividing 500 by 558, we get 0 with a remainder of 500.
The next digit of our result is 0. 
Result so far: 54888.025
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 13:
The number 558 fits into 5000 8 times, leaving a remainder of 536.
The number 8 becomes the next digit in our result. 
Result so far: 54888.02508
Deduct 4464 from 5000 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Going ahead to step 14:
If we divide 5360 by 558, we get 9 and a remainder of 338.
Use 9 as the next digit of our solution. 
Result so far: 54888.025089
Subtracting 5022 from 5360 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Step 15:
558 can be fit into 3380 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 54888.0250896
Deduct 3348 from 3380 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 16:
The number 558 fits into 320 0 times, leaving a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 54888.0250896
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

After the division, we end up with 54888.0250896 and a remainder of 3.2e-07.
