Let's divide 728203 by 4
The aim is to understand the frequency of 4 in 728203.

On to step 1:
4 can be fit into 7 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 4 from 7 and we're left with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 4

Going ahead to step 2:
32 divided by 4 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 32 from 32 leaves us with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 4

On to step 3:
When dividing 8 by 4, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 182.0
The remainder is 0 after subtracting 8 from 8.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 4

Moving on to step 4:
4 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 1820.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 4

Step 5:
If we divide 20 by 4, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 18205.0
Subtracting 20 from 20 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 4

Step 6:
4 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 182050.0
Subtracting 0 from 3 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.

Step 7:
30 divided by 4 is 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 182050.7
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.

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: 182050.75
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.

On to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 182050.75
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.

On to step 10:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 182050.75
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 outcome is 182050.75, with a leftover of 0.0.
