We look at the division of 79712968 by 558 
The aim is to understand the frequency of 558 in 79712968.

Moving on to step 1:
When dividing 7 by 558, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 558

Let's proceed to step 2:
When dividing 79 by 558, we get 0 with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 558

Advancing to step 3:
When dividing 797 by 558, we get 1 with a remainder of 239.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 558 away from 797, we end up with 239.
Fetch the next digit (1) from the dividend, attach it to 239 and continue: 2391 / 558

Step 4:
558 goes into 2391 4 times with a remainder of 159.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 2232 from 2391 to get 159.
Fetch the next digit (2) from the dividend, attach it to 159 and continue: 1592 / 558

On to step 5:
If we divide 1592 by 558, we get 2 and a remainder of 476.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
If we subtract 1116 from 1592, we get 476.
Fetch the next digit (9) from the dividend, attach it to 476 and continue: 4769 / 558

Let's proceed to step 6:
The number 558 fits into 4769 8 times, leaving a remainder of 305.
Put 8 as the next digit of the answer. 
Result so far: 1428.0
If we subtract 4464 from 4769, we get 305.
Include the next digit (6) from the dividend after 305, then repeat: 3056 / 558

Let's proceed to step 7:
When dividing 3056 by 558, we get 5 with a remainder of 266.
Write down 5 as next digit of the result. 
Result so far: 14285.0
Subtracting 2790 from 3056 leaves us with 266.
Grab the next digit (8) from the dividend, add it to 266, then carry on: 2668 / 558

On to step 8:
When dividing 2668 by 558, we get 4 with a remainder of 436.
Put 4 as the next digit of the answer. 
Result so far: 142854.0
If we subtract 2232 from 2668, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Moving on to step 9:
4360 divided by 558 is 7 with a remainder of 454.
Put 7 as the next digit of the answer. 
Result so far: 142854.7
Subtract 3906 from 4360 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 10:
The number 558 fits into 4540 8 times, leaving a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 142854.78
Subtract 4464 from 4540 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
If we divide 760 by 558, we get 1 and a remainder of 202.
Record the quotient 1 as the next digit in the result. 
Result so far: 142854.781
If we subtract 558 from 760, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 12:
558 can be fit into 2020 3 times, resulting in a remainder of 346.
Write down 3 as next digit of the result. 
Result so far: 142854.7813
Deduct 1674 from 2020 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 13:
If we divide 3460 by 558, we get 6 and a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 142854.78136
If we subtract 3348 from 3460, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 14:
558 can be fit into 1120 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 142854.781362
If we subtract 1116 from 1120, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 15:
558 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 142854.781362
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 16:
The number 558 fits into 400 0 times, leaving a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 142854.781362
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 142854.781362, with a leftover of 4e-07.
