Let's divide 363431 by 4
The aim is to understand the frequency of 4 in 363431.

On to step 1:
3 divided by 4 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 4

Going ahead to step 2:
4 can be fit into 36 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 36 from 36 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 4

Moving on to step 3:
3 divided by 4 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
If we take 0 away from 3, we end up with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 4

Advancing to step 4:
34 divided by 4 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 908.0
Deduct 32 from 34 and we're left with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 4

Going ahead to step 5:
When dividing 23 by 4, we get 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 9085.0
Subtracting 20 from 23 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 4

Moving on to step 6:
If we divide 31 by 4, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 90857.0
Subtracting 28 from 31 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
If we divide 30 by 4, we get 7 and a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 90857.7
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
If we divide 20 by 4, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 90857.75
If we take 20 away from 20, 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.

On to step 9:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 90857.75
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.

Let's proceed to step 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 90857.75
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.

In conclusion, the division gives 90857.75 with a balance of 0.0.
