17870632 ÷ 558 
The aim is to understand the frequency of 558 in 17870632.

On to step 1:
When dividing 1 by 558, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 558

Going ahead to step 2:
558 can be fit into 17 0 times, resulting in a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 558

Moving on to step 3:
558 can be fit into 178 0 times, resulting in a remainder of 178.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 178 to get 178.
Append the next digit (7) from the dividend to 178 and continue with: 1787 / 558

Going ahead to step 4:
558 goes into 1787 3 times with a remainder of 113.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 1674 from 1787, we get 113.
Append the next digit (0) from the dividend to 113 and continue with: 1130 / 558

Moving on to step 5:
1130 divided by 558 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
If we take 1116 away from 1130, we end up with 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 558

On to step 6:
If we divide 146 by 558, we get 0 and a remainder of 146.
Record the quotient 0 as the next digit in the result. 
Result so far: 320.0
The remainder is 146 after subtracting 0 from 146.
Bring next digit (3) of the dividend behind the 146 and repeat the process: 1463 / 558

Advancing to step 7:
When dividing 1463 by 558, we get 2 with a remainder of 347.
Write down 2 as next digit of the result. 
Result so far: 3202.0
Deduct 1116 from 1463 and we're left with 347.
Bring next digit (2) of the dividend behind the 347 and repeat the process: 3472 / 558

Let's proceed to step 8:
558 can be fit into 3472 6 times, resulting in a remainder of 124.
The next digit of our result is 6. 
Result so far: 32026.0
The remainder is 124 after subtracting 3348 from 3472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 9:
If we divide 1240 by 558, we get 2 and a remainder of 124.
Use 2 as the next digit of our solution. 
Result so far: 32026.2
If we take 1116 away from 1240, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 10:
558 goes into 1240 2 times with a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 32026.22
If we subtract 1116 from 1240, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final result is 32026.22 with a remainder of 0.124.
