We're dividing 339474 by 42 
The aim is to understand the frequency of 42 in 339474.

Let's proceed to step 1:
3 divided by 42 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 42

Going ahead to step 2:
If we divide 33 by 42, we get 0 and a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 42

Step 3:
If we divide 339 by 42, we get 8 and a remainder of 3.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 336 from 339, we get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 42

Advancing to step 4:
The number 42 fits into 34 0 times, leaving a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Subtracting 0 from 34 leaves us with 34.
Grab the next digit (7) from the dividend, add it to 34, then carry on: 347 / 42

Step 5:
42 can be fit into 347 8 times, resulting in a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 808.0
Subtract 336 from 347 to get 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 42

Going ahead to step 6:
114 divided by 42 is 2 with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 8082.0
Subtract 84 from 114 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
If we divide 300 by 42, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 8082.7
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
If we divide 60 by 42, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 8082.71
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
180 divided by 42 is 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 8082.714
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.

Moving on to step 10:
120 divided by 42 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 8082.7142
Subtracting 84 from 120 leaves us 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.

Step 11:
42 goes into 360 8 times with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 8082.71428
If we take 336 away from 360, we end up 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.

On to step 12:
When dividing 240 by 42, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 8082.714285
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
42 can be fit into 300 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 8082.7142857
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
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: 8082.71428571
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 8082.71428571 with a balance of 1.8e-08.
