We look at the division of 852341 by 4 
The aim is to understand the frequency of 4 in 852341.

Advancing to step 1:
4 goes into 8 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 8 from 8 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 4

Advancing to step 2:
When dividing 5 by 4, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 1 after subtracting 4 from 5.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 4

On to step 3:
The number 4 fits into 12 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 213.0
The remainder is 0 after subtracting 12 from 12.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 4

Going ahead to step 4:
The number 4 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 2130.0
If we subtract 0 from 3, we get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 4

Going ahead to step 5:
4 can be fit into 34 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 21308.0
If we subtract 32 from 34, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 4

Let's proceed to step 6:
When dividing 21 by 4, we get 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 213085.0
If we take 20 away from 21, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 4 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 213085.2
Subtracting 8 from 10 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 8:
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: 213085.25
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.

Moving on 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: 213085.25
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.

Advancing to step 10:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 213085.25
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.

Our division results in 213085.25 with a remaining 0.0.
