We look at the division of 155608 by 4 
The aim is to understand the frequency of 4 in 155608.

On to step 1:
4 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 4

Going ahead to step 2:
If we divide 15 by 4, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 12 from 15 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 4

Going ahead to step 3:
If we divide 35 by 4, we get 8 and a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtract 32 from 35 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 4

Step 4:
If we divide 36 by 4, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 389.0
If we subtract 36 from 36, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 4

Moving on to step 5:
0 divided by 4 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3890.0
Deduct 0 from 0 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 6:
The number 4 fits into 8 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 38902.0
Deduct 8 from 8 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.

Going ahead to step 7:
If we divide 0 by 4, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 38902.0
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.

On to step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 38902.0
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.

In conclusion, the division gives 38902.0 with a balance of 0.0.
