We're dividing 841484 by 42 
The aim is to understand the frequency of 42 in 841484.

Advancing to step 1:
8 divided by 42 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 42

Moving on to step 2:
42 can be fit into 84 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 84 from 84 and we're left with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 42

Let's proceed to step 3:
If we divide 1 by 42, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 1 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 42

Going ahead to step 4:
The number 42 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 200.0
The remainder is 14 after subtracting 0 from 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 42

On to step 5:
When dividing 148 by 42, we get 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 2003.0
Subtract 126 from 148 to get 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 42

Going ahead to step 6:
When dividing 224 by 42, we get 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 20035.0
If we subtract 210 from 224, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
The number 42 fits into 140 3 times, leaving a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 20035.3
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
42 goes into 140 3 times with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 20035.33
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 20035.33 with a remaining 0.014.
