We divide 349445 by 42
The aim is to understand the frequency of 42 in 349445.

Let's proceed to step 1:
When dividing 3 by 42, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 42

On to step 2:
34 divided by 42 is 0 with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 42

Advancing to step 3:
349 divided by 42 is 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 13 after subtracting 336 from 349.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 42

Going ahead to step 4:
The number 42 fits into 134 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
Subtract 126 from 134 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 42

Advancing to step 5:
If we divide 84 by 42, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 832.0
The remainder is 0 after subtracting 84 from 84.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 42

On to step 6:
42 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 8320.0
Subtracting 0 from 5 leaves us 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.

Let's proceed to step 7:
50 divided by 42 is 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 8320.1
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.

Advancing to step 8:
When dividing 80 by 42, we get 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 8320.11
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.

The final outcome is 8320.11, with a leftover of 0.038.
