We look at the division of 985572 by 4 
The aim is to understand the frequency of 4 in 985572.

Let's proceed to step 1:
9 divided by 4 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 1 after subtracting 8 from 9.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 4

On to step 2:
18 divided by 4 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we take 16 away from 18, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 4

On to step 3:
The number 4 fits into 25 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 246.0
If we take 24 away from 25, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 4

Let's proceed to step 4:
4 can be fit into 15 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 2463.0
If we take 12 away from 15, we end up with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 4

Let's proceed to step 5:
37 divided by 4 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 24639.0
If we subtract 36 from 37, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 4

Going ahead to step 6:
4 goes into 12 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 246393.0
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.

Advancing to step 7:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 246393.0
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.

Going ahead to step 8:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 246393.0
Subtracting 0 from 0 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.

After the division, we end up with 246393.0 and a remainder of 0.0.
