We look at the division of 968530 by 4 
The aim is to understand the frequency of 4 in 968530.

Going ahead to step 1:
4 can be fit into 9 2 times, resulting in a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 8 from 9 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 4

Going ahead to step 2:
4 goes into 16 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 24.0
Deduct 16 from 16 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 4

Moving on to step 3:
4 goes into 8 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 242.0
If we take 8 away from 8, we end up with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 4

Moving on to step 4:
4 goes into 5 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 2421.0
If we take 4 away from 5, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 4

Advancing to step 5:
4 can be fit into 13 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 24213.0
If we take 12 away from 13, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 4

Moving on to step 6:
4 can be fit into 10 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 242132.0
Deduct 8 from 10 and we're left 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.

On to step 7:
The number 4 fits into 20 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 242132.5
Deduct 20 from 20 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.

Advancing to step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 242132.5
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.

Let's proceed to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 242132.5
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.

Our division results in 242132.5 with a remaining 0.0.
