We're dividing 633438 by 4 
The aim is to understand the frequency of 4 in 633438.

Going ahead to step 1:
When dividing 6 by 4, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 4 from 6 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 4

On to step 2:
The number 4 fits into 23 5 times, leaving a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 20 from 23, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 4

On to step 3:
If we divide 33 by 4, we get 8 and a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 158.0
The remainder is 1 after subtracting 32 from 33.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 4

On to step 4:
The number 4 fits into 14 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 1583.0
Deduct 12 from 14 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 4

Moving on to step 5:
When dividing 23 by 4, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 15835.0
Subtracting 20 from 23 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 4

Going ahead to step 6:
38 divided by 4 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 158359.0
If we take 36 away from 38, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
20 divided by 4 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 158359.5
Subtract 20 from 20 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.

Moving on to step 8:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 158359.5
Subtracting 0 from 0 leaves us 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 9:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 158359.5
If we subtract 0 from 0, we 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.

After the division, we end up with 158359.5 and a remainder of 0.0.
