Let's divide 649648 by 42
The aim is to understand the frequency of 42 in 649648.

Let's proceed to step 1:
6 divided by 42 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 42

Going ahead to step 2:
When dividing 64 by 42, we get 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 22 after subtracting 42 from 64.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 42

On to step 3:
If we divide 229 by 42, we get 5 and a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 210 away from 229, we end up with 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 42

Advancing to step 4:
42 goes into 196 4 times with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 154.0
If we take 168 away from 196, we end up with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 42

Let's proceed to step 5:
42 can be fit into 284 6 times, resulting in a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 1546.0
Subtracting 252 from 284 leaves us with 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 42

Step 6:
42 can be fit into 328 7 times, resulting in a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 15467.0
Subtract 294 from 328 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.

Step 7:
When dividing 340 by 42, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 15467.8
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
40 divided by 42 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 15467.8
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
If we divide 400 by 42, we get 9 and a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 15467.809
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
220 divided by 42 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 15467.8095
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
42 can be fit into 100 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 15467.80952
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 15467.809523
If we subtract 126 from 160, we 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 13:
42 goes into 340 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 15467.8095238
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
If we divide 40 by 42, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 15467.8095238
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 15467.8095238 with a balance of 4e-08.
