We look at the division of 85352 by 4 
The aim is to understand the frequency of 4 in 85352.

Let's proceed to step 1:
8 divided by 4 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 0 after subtracting 8 from 8.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 4

Advancing to step 2:
If we divide 5 by 4, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 4 from 5 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 4

Advancing to step 3:
13 divided by 4 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 213.0
Subtracting 12 from 13 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 4

Moving on to step 4:
The number 4 fits into 15 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 2133.0
If we subtract 12 from 15, we get 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 4

Going ahead to step 5:
When dividing 32 by 4, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 21338.0
Subtract 32 from 32 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.

Step 6:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 21338.0
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.

Step 7:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21338.0
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.

The quotient of the division is 21338.0, and the remainder is 0.0.
