Let's divide 74575 by 42
The aim is to understand the frequency of 42 in 74575.

Advancing to step 1:
The number 42 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 42

On to step 2:
When dividing 74 by 42, we get 1 with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 42 from 74, we get 32.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 42

Let's proceed to step 3:
When dividing 325 by 42, we get 7 with a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 294 from 325 and we're left with 31.
Bring next digit (7) of the dividend behind the 31 and repeat the process: 317 / 42

Moving on to step 4:
42 can be fit into 317 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 177.0
If we subtract 294 from 317, we get 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 42

Moving on to step 5:
42 goes into 235 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 1775.0
The remainder is 25 after subtracting 210 from 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 6:
The number 42 fits into 250 5 times, leaving a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 1775.5
Deduct 210 from 250 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
400 divided by 42 is 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 1775.59
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
If we divide 220 by 42, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 1775.595
If we take 210 away from 220, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 1775.5952
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
42 goes into 160 3 times with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 1775.59523
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
The number 42 fits into 340 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 1775.595238
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
If we divide 40 by 42, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1775.595238
Subtracting 0 from 40 leaves us with 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 13:
400 divided by 42 is 9 with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 1775.59523809
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 1775.59523809 with a remaining 2.2e-08.
