We look at the division of 51652 by 4 
The aim is to understand the frequency of 4 in 51652.

On to step 1:
When dividing 5 by 4, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 4 from 5 leaves us with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 4

Moving on to step 2:
The number 4 fits into 11 2 times, leaving a remainder of 3.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 8 from 11 and we're left with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 4

On to step 3:
The number 4 fits into 36 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
Subtracting 36 from 36 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 4

Advancing to step 4:
4 goes into 5 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1291.0
Subtracting 4 from 5 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 4

Step 5:
The number 4 fits into 12 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 12913.0
Subtracting 12 from 12 leaves us 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.

Going ahead to step 6:
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: 12913.0
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.

Going ahead to step 7:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12913.0
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.

The final outcome is 12913.0, with a leftover of 0.0.
