We look at the division of 965556 by 4 
The aim is to understand the frequency of 4 in 965556.

Going ahead to step 1:
When dividing 9 by 4, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 8 from 9 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 4

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: 24.0
If we take 16 away from 16, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 4

Advancing to step 3:
5 divided by 4 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 241.0
Subtract 4 from 5 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 4

Let's proceed to step 4:
When dividing 15 by 4, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 2413.0
Deduct 12 from 15 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 4

On to step 5:
When dividing 35 by 4, we get 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 24138.0
Deduct 32 from 35 and we're left with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 4

Step 6:
If we divide 36 by 4, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 241389.0
Subtract 36 from 36 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.

Let's proceed to step 7:
If we divide 0 by 4, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 241389.0
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.

Advancing to step 8:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 241389.0
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 result is 241389.0 with a remainder of 0.0.
