We're dividing 191357 by 42 
The aim is to understand the frequency of 42 in 191357.

Going ahead to step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 42

Step 2:
The number 42 fits into 19 0 times, leaving a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 42

Moving on to step 3:
The number 42 fits into 191 4 times, leaving a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 168 from 191 and we're left with 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 42

Advancing to step 4:
When dividing 233 by 42, we get 5 with a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtracting 210 from 233 leaves us with 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 42

Advancing to step 5:
42 can be fit into 235 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 455.0
If we subtract 210 from 235, we get 25.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 42

Step 6:
The number 42 fits into 257 6 times, leaving a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 4556.0
If we take 252 away from 257, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
42 goes into 50 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 4556.1
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
When dividing 80 by 42, we get 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 4556.11
Subtract 42 from 80 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 4556.11 with a balance of 0.038.
