We're dividing 926896 by 3 
The aim is to understand the frequency of 3 in 926896.

Going ahead to step 1:
9 divided by 3 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 9 from 9, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 3

Step 2:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 2, we get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 3

Step 3:
26 divided by 3 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 308.0
Subtracting 24 from 26 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 3

Going ahead to step 4:
The number 3 fits into 28 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 3089.0
Deduct 27 from 28 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 3

Advancing to step 5:
3 can be fit into 19 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 30896.0
If we take 18 away from 19, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 3

Advancing to step 6:
16 divided by 3 is 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 308965.0
If we subtract 15 from 16, 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:
When dividing 10 by 3, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 308965.3
If we take 9 away from 10, we end up 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.

Going ahead to step 8:
3 goes into 10 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 308965.33
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 308965.33 and a remainder of 0.001.
