We're dividing 56503 by 4 
The aim is to understand the frequency of 4 in 56503.

Going ahead to step 1:
4 goes into 5 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 4 from 5 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 4

Advancing to step 2:
The number 4 fits into 16 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 16 from 16, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 4

Advancing to step 3:
5 divided by 4 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
The remainder is 1 after subtracting 4 from 5.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 4

On to step 4:
The number 4 fits into 10 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 1412.0
Subtracting 8 from 10 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 4

On to step 5:
23 divided by 4 is 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 14125.0
Subtracting 20 from 23 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.

On to step 6:
4 goes into 30 7 times with a remainder of 2.
The next digit of our result is 7. 
Result so far: 14125.7
Subtracting 28 from 30 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.

Let's proceed to step 7:
4 goes into 20 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 14125.75
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.

Advancing to step 8:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14125.75
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.

Going ahead to step 9:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14125.75
Deduct 0 from 0 and we're left 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 14125.75, with a leftover of 0.0.
