We're dividing 108784 by 3 
The aim is to understand the frequency of 3 in 108784.

Step 1:
1 divided by 3 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 3

Moving on to step 2:
When dividing 10 by 3, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 9 from 10 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

Step 3:
18 divided by 3 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 36.0
Deduct 18 from 18 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 3

Step 4:
When dividing 7 by 3, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 362.0
If we subtract 6 from 7, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

Advancing to step 5:
18 divided by 3 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 3626.0
Subtracting 18 from 18 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Going ahead to step 6:
The number 3 fits into 4 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 36261.0
If we subtract 3 from 4, we get 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:
If we divide 10 by 3, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 36261.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 36261.33
Subtracting 9 from 10 leaves us 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.

After the division, we end up with 36261.33 and a remainder of 0.001.
