80385911 ÷ 558 
The aim is to understand the frequency of 558 in 80385911.

On to step 1:
When dividing 8 by 558, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 558

Step 2:
When dividing 80 by 558, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 558

Let's proceed to step 3:
The number 558 fits into 803 1 times, leaving a remainder of 245.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 558 from 803 to get 245.
Include the next digit (8) from the dividend after 245, then repeat: 2458 / 558

Moving on to step 4:
The number 558 fits into 2458 4 times, leaving a remainder of 226.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 226 after subtracting 2232 from 2458.
Grab the next digit (5) from the dividend, add it to 226, then carry on: 2265 / 558

Advancing to step 5:
If we divide 2265 by 558, we get 4 and a remainder of 33.
Put 4 as the next digit of the answer. 
Result so far: 144.0
The remainder is 33 after subtracting 2232 from 2265.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 558

Step 6:
If we divide 339 by 558, we get 0 and a remainder of 339.
Record the quotient 0 as the next digit in the result. 
Result so far: 1440.0
If we take 0 away from 339, we end up with 339.
Take the next digit (1) from the dividend and append it to 339, then repeat: 3391 / 558

Going ahead to step 7:
3391 divided by 558 is 6 with a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 14406.0
If we take 3348 away from 3391, we end up with 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 558

Let's proceed to step 8:
If we divide 431 by 558, we get 0 and a remainder of 431.
The next digit of our result is 0. 
Result so far: 144060.0
Subtracting 0 from 431 leaves us with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

On to step 9:
558 goes into 4310 7 times with a remainder of 404.
Use 7 as the next digit of our solution. 
Result so far: 144060.7
Subtracting 3906 from 4310 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 10:
When dividing 4040 by 558, we get 7 with a remainder of 134.
Use 7 as the next digit of our solution. 
Result so far: 144060.77
Subtracting 3906 from 4040 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

The quotient of the division is 144060.77, and the remainder is 0.134.
