We're dividing 649567 by 42 
The aim is to understand the frequency of 42 in 649567.

Moving on to step 1:
If we divide 6 by 42, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 42

Advancing to step 2:
When dividing 64 by 42, we get 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 42 from 64 leaves us with 22.
Grab the next digit (9) from the dividend, add it to 22, then carry on: 229 / 42

Going ahead to step 3:
42 can be fit into 229 5 times, resulting in a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 210 from 229, we get 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 42

On to step 4:
If we divide 195 by 42, we get 4 and a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
If we subtract 168 from 195, we get 27.
Bring next digit (6) of the dividend behind the 27 and repeat the process: 276 / 42

Going ahead to step 5:
When dividing 276 by 42, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 1546.0
If we subtract 252 from 276, we get 24.
Append the next digit (7) from the dividend to 24 and continue with: 247 / 42

Let's proceed to step 6:
42 can be fit into 247 5 times, resulting in a remainder of 37.
The next digit of our result is 5. 
Result so far: 15465.0
If we subtract 210 from 247, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
42 can be fit into 370 8 times, resulting in a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 15465.8
Subtract 336 from 370 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 15465.88
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 15465.88 with a remaining 0.004.
