We're dividing 156577 by 4 
The aim is to understand the frequency of 4 in 156577.

Going ahead to step 1:
1 divided by 4 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 4

Going ahead to step 2:
4 can be fit into 15 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 12 from 15, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 4

Let's proceed to step 3:
The number 4 fits into 36 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Deduct 36 from 36 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 4

Going ahead to step 4:
5 divided by 4 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 391.0
Subtracting 4 from 5 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 4

On to step 5:
17 divided by 4 is 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 3914.0
If we subtract 16 from 17, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 4

On to step 6:
17 divided by 4 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 39144.0
Deduct 16 from 17 and we're left 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.

On to step 7:
4 goes into 10 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 39144.2
The remainder is 2 after subtracting 8 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 39144.25
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.

On to step 9:
0 divided by 4 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39144.25
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.

Step 10:
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: 39144.25
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 39144.25 with a remaining 0.0.
