402292 ÷ 3 
The aim is to understand the frequency of 3 in 402292.

On to step 1:
The number 3 fits into 4 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 3 from 4.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

Let's proceed to step 2:
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: 13.0
The remainder is 1 after subtracting 9 from 10.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 3

Going ahead to step 3:
12 divided by 3 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 134.0
If we subtract 12 from 12, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 3

On to step 4:
If we divide 2 by 3, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 1340.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 3

Going ahead to step 5:
When dividing 29 by 3, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 13409.0
Subtracting 27 from 29 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 3

Step 6:
If we divide 22 by 3, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 134097.0
Subtract 21 from 22 to 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.

Going ahead to step 7:
3 goes into 10 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 134097.3
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.

Going ahead to step 8:
3 goes into 10 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 134097.33
Subtract 9 from 10 to 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.

Our division results in 134097.33 with a remaining 0.001.
