Let's divide 84540542 by 125
The aim is to understand the frequency of 125 in 84540542.

On to step 1:
125 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 125

Advancing to step 2:
When dividing 84 by 125, we get 0 with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Append the next digit (5) from the dividend to 84 and continue with: 845 / 125

Moving on to step 3:
When dividing 845 by 125, we get 6 with a remainder of 95.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 750 from 845 leaves us with 95.
Grab the next digit (4) from the dividend, add it to 95, then carry on: 954 / 125

Advancing to step 4:
125 goes into 954 7 times with a remainder of 79.
Use 7 as the next digit of our solution. 
Result so far: 67.0
The remainder is 79 after subtracting 875 from 954.
Include the next digit (0) from the dividend after 79, then repeat: 790 / 125

Let's proceed to step 5:
125 can be fit into 790 6 times, resulting in a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 676.0
The remainder is 40 after subtracting 750 from 790.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 125

Going ahead to step 6:
125 goes into 405 3 times with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 6763.0
Subtract 375 from 405 to get 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 125

Let's proceed to step 7:
125 goes into 304 2 times with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 67632.0
If we subtract 250 from 304, we get 54.
Fetch the next digit (2) from the dividend, attach it to 54 and continue: 542 / 125

Moving on to step 8:
When dividing 542 by 125, we get 4 with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 676324.0
The remainder is 42 after subtracting 500 from 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
When dividing 420 by 125, we get 3 with a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 676324.3
Subtract 375 from 420 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 10:
The number 125 fits into 450 3 times, leaving a remainder of 75.
Record the quotient 3 as the next digit in the result. 
Result so far: 676324.33
Subtracting 375 from 450 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final outcome is 676324.33, with a leftover of 0.075.
