We're dividing 548107 by 42 
The aim is to understand the frequency of 42 in 548107.

Going ahead to step 1:
When dividing 5 by 42, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 42

On to step 2:
54 divided by 42 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 42 from 54 leaves us with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 42

Let's proceed to step 3:
128 divided by 42 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 126 from 128 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 42

Moving on to step 4:
If we divide 21 by 42, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 130.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 42

Going ahead to step 5:
If we divide 210 by 42, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 1305.0
If we subtract 210 from 210, we get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 42

Step 6:
If we divide 7 by 42, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 13050.0
If we take 0 away from 7, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
The number 42 fits into 70 1 times, leaving a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 13050.1
Deduct 42 from 70 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.

Step 8:
The number 42 fits into 280 6 times, leaving a remainder of 28.
The next digit of our result is 6. 
Result so far: 13050.16
Subtracting 252 from 280 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.

Let's proceed to step 9:
280 divided by 42 is 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 13050.166
If we subtract 252 from 280, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 13050.166 with a remaining 0.0028.
