We look at the division of 731358 by 42 
The aim is to understand the frequency of 42 in 731358.

Let's proceed to step 1:
The number 42 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 42

Step 2:
The number 42 fits into 73 1 times, leaving a remainder of 31.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 42 from 73 to get 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 42

Moving on to step 3:
The number 42 fits into 311 7 times, leaving a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 294 from 311 to get 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 42

Step 4:
173 divided by 42 is 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 174.0
If we take 168 away from 173, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 42

Advancing to step 5:
The number 42 fits into 55 1 times, leaving a remainder of 13.
The next digit of our result is 1. 
Result so far: 1741.0
Subtracting 42 from 55 leaves us with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 42

On to step 6:
When dividing 138 by 42, we get 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 17413.0
Subtract 126 from 138 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
If we divide 120 by 42, we get 2 and a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 17413.2
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
When dividing 360 by 42, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 17413.28
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
42 goes into 240 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 17413.285
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
300 divided by 42 is 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 17413.2857
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 17413.28571
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
When dividing 180 by 42, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 17413.285714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
If we divide 120 by 42, we get 2 and a remainder of 36.
The next digit of our result is 2. 
Result so far: 17413.2857142
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
360 divided by 42 is 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 17413.28571428
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 17413.28571428 with a balance of 2.4e-08.
