We look at the division of 126934 by 4 
The aim is to understand the frequency of 4 in 126934.

Step 1:
If we divide 1 by 4, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 4

Going ahead to step 2:
If we divide 12 by 4, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 12 from 12 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 4

Let's proceed to step 3:
If we divide 6 by 4, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtract 4 from 6 to get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 4

Let's proceed to step 4:
When dividing 29 by 4, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 317.0
The remainder is 1 after subtracting 28 from 29.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 4

On to step 5:
If we divide 13 by 4, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3173.0
Subtracting 12 from 13 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 4

Step 6:
When dividing 14 by 4, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 31733.0
If we take 12 away from 14, 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.
Record the quotient 5 as the next digit in the result. 
Result so far: 31733.5
If we subtract 20 from 20, 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.

Going ahead to step 8:
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: 31733.5
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.

Advancing to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31733.5
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 final result is 31733.5 with a remainder of 0.0.
