We look at the division of 89750864 by 42 
The aim is to understand the frequency of 42 in 89750864.

Advancing to step 1:
8 divided by 42 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 42

Advancing to step 2:
If we divide 89 by 42, we get 2 and a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 84 from 89, we get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 42

On to step 3:
The number 42 fits into 57 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 42 from 57 leaves us with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 42

Step 4:
42 goes into 155 3 times with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 213.0
If we take 126 away from 155, we end up with 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 42

Let's proceed to step 5:
If we divide 290 by 42, we get 6 and a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 2136.0
The remainder is 38 after subtracting 252 from 290.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 42

Advancing to step 6:
When dividing 388 by 42, we get 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 21369.0
Deduct 378 from 388 and we're left with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 42

Going ahead to step 7:
106 divided by 42 is 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 213692.0
Deduct 84 from 106 and we're left with 22.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 42

Let's proceed to step 8:
When dividing 224 by 42, we get 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 2136925.0
Subtracting 210 from 224 leaves us 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.

Step 9:
If we divide 140 by 42, we get 3 and a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 2136925.3
If we take 126 away from 140, we end up 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.

Advancing to step 10:
140 divided by 42 is 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 2136925.33
Deduct 126 from 140 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.

The final result is 2136925.33 with a remainder of 0.014.
