481138 divided by 42 
The aim is to understand the frequency of 42 in 481138.

Advancing to step 1:
When dividing 4 by 42, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 42

On to step 2:
When dividing 48 by 42, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 42 away from 48, we end up with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 42

Going ahead to step 3:
The number 42 fits into 61 1 times, leaving a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 19 after subtracting 42 from 61.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 42

Going ahead to step 4:
42 can be fit into 191 4 times, resulting in a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 114.0
If we take 168 away from 191, we end up with 23.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 42

Let's proceed to step 5:
233 divided by 42 is 5 with a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 1145.0
Subtracting 210 from 233 leaves us with 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 42

Going ahead to step 6:
42 goes into 238 5 times with a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 11455.0
Subtracting 210 from 238 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
The number 42 fits into 280 6 times, leaving a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 11455.6
Deduct 252 from 280 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
The number 42 fits into 280 6 times, leaving a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 11455.66
Deduct 252 from 280 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 11455.66 and a remainder of 0.028.
