We're dividing 791410 by 42 
The aim is to understand the frequency of 42 in 791410.

Advancing to step 1:
When dividing 7 by 42, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 42

Step 2:
42 can be fit into 79 1 times, resulting in a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 42 away from 79, we end up with 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 42

Moving on to step 3:
The number 42 fits into 371 8 times, leaving a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 336 from 371 and we're left with 35.
Grab the next digit (4) from the dividend, add it to 35, then carry on: 354 / 42

Step 4:
When dividing 354 by 42, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 188.0
Subtract 336 from 354 to get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 42

On to step 5:
42 can be fit into 181 4 times, resulting in a remainder of 13.
The next digit of our result is 4. 
Result so far: 1884.0
Subtracting 168 from 181 leaves us with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 42

On to step 6:
When dividing 130 by 42, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 18843.0
Deduct 126 from 130 and we're left 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.

On to step 7:
When dividing 40 by 42, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 18843.0
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.

Moving on to step 8:
400 divided by 42 is 9 with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 18843.09
Subtracting 378 from 400 leaves us 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.

Going ahead to step 9:
When dividing 220 by 42, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 18843.095
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
42 goes into 100 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 18843.0952
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.

On to step 11:
42 can be fit into 160 3 times, resulting in a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 18843.09523
Deduct 126 from 160 and we're left 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.

Moving on to step 12:
340 divided by 42 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 18843.095238
If we take 336 away from 340, we end up 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.

Moving on to step 13:
40 divided by 42 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 18843.095238
The remainder is 40 after subtracting 0 from 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 14:
When dividing 400 by 42, we get 9 with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 18843.09523809
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.

In conclusion, the division gives 18843.09523809 with a balance of 2.2e-08.
