We're dividing 642392 by 4 
The aim is to understand the frequency of 4 in 642392.

Moving on to step 1:
The number 4 fits into 6 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 4 from 6 to get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 4

Going ahead to step 2:
24 divided by 4 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 24 from 24 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 4

Step 3:
4 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 160.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 4

Going ahead to step 4:
If we divide 23 by 4, we get 5 and a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 1605.0
The remainder is 3 after subtracting 20 from 23.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 4

Advancing to step 5:
4 can be fit into 39 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 16059.0
Subtract 36 from 39 to get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 4

Moving on to step 6:
If we divide 32 by 4, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 160598.0
Deduct 32 from 32 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
When dividing 0 by 4, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 160598.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
4 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 160598.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 160598.0, and the remainder is 0.0.
