647490 ÷ 42 
The aim is to understand the frequency of 42 in 647490.

Let's proceed to step 1:
42 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 42

Moving on to step 2:
42 goes into 64 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 42 away from 64, we end up with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 42

Moving on to step 3:
When dividing 227 by 42, we get 5 with a remainder of 17.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 210 from 227 leaves us with 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 42

Let's proceed to step 4:
When dividing 174 by 42, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 154.0
The remainder is 6 after subtracting 168 from 174.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 42

Let's proceed to step 5:
When dividing 69 by 42, we get 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1541.0
The remainder is 27 after subtracting 42 from 69.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 42

Advancing to step 6:
42 goes into 270 6 times with a remainder of 18.
The next digit of our result is 6. 
Result so far: 15416.0
Subtract 252 from 270 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
If we divide 180 by 42, we get 4 and a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 15416.4
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
42 goes into 120 2 times with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 15416.42
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
When dividing 360 by 42, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 15416.428
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 15416.4285
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
42 goes into 300 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 15416.42857
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 15416.428571
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
If we divide 180 by 42, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 15416.4285714
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
120 divided by 42 is 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 15416.42857142
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 15416.42857142 with a balance of 3.6e-08.
