787539 ÷ 4 
The aim is to understand the frequency of 4 in 787539.

Step 1:
4 goes into 7 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we take 4 away from 7, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 4

Moving on to step 2:
The number 4 fits into 38 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 36 away from 38, we end up with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 4

Step 3:
4 goes into 27 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 196.0
Subtract 24 from 27 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 4

Let's proceed to step 4:
When dividing 35 by 4, we get 8 with a remainder of 3.
The next digit of our result is 8. 
Result so far: 1968.0
If we subtract 32 from 35, we get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 4

Advancing to step 5:
If we divide 33 by 4, we get 8 and a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 19688.0
If we take 32 away from 33, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 4

Step 6:
The number 4 fits into 19 4 times, leaving a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 196884.0
Subtract 16 from 19 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
When dividing 30 by 4, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 196884.7
If we take 28 away from 30, we end up 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.

Let's proceed to step 8:
If we divide 20 by 4, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 196884.75
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.

Moving on to step 9:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 196884.75
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.

Advancing to step 10:
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: 196884.75
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 196884.75 with a remaining 0.0.
