We divide 727536 by 4
The aim is to understand the frequency of 4 in 727536.

Moving on to step 1:
If we divide 7 by 4, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 4 from 7 leaves us with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 4

On to step 2:
32 divided by 4 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 32 from 32 and we're left with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 4

On to step 3:
4 can be fit into 7 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 181.0
If we take 4 away from 7, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 4

On to step 4:
The number 4 fits into 35 8 times, leaving a remainder of 3.
The next digit of our result is 8. 
Result so far: 1818.0
The remainder is 3 after subtracting 32 from 35.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 4

On to step 5:
4 goes into 33 8 times with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 18188.0
If we subtract 32 from 33, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 4

Advancing to step 6:
16 divided by 4 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 181884.0
Subtract 16 from 16 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.

Going ahead to step 7:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 181884.0
The remainder is 0 after subtracting 0 from 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 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 181884.0
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.

After the division, we end up with 181884.0 and a remainder of 0.0.
