Let's divide 363201 by 4
The aim is to understand the frequency of 4 in 363201.

On to step 1:
4 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 4

On to step 2:
The number 4 fits into 36 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 36 from 36, we get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 4

Going ahead to step 3:
If we divide 3 by 4, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 4

Step 4:
4 can be fit into 32 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 908.0
If we take 32 away from 32, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 4

On to step 5:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9080.0
Subtract 0 from 0 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 4

Going ahead to step 6:
4 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 90800.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 4 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 90800.2
Subtracting 8 from 10 leaves us 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.

Going ahead to step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 90800.25
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.

Going ahead to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 90800.25
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.

Going ahead to step 10:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 90800.25
The remainder is 0 after subtracting 0 from 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 90800.25 and a remainder of 0.0.
