We're dividing 290134 by 3 
The aim is to understand the frequency of 3 in 290134.

Advancing to step 1:
When dividing 2 by 3, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 3

On to step 2:
When dividing 29 by 3, we get 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 27 from 29 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 3

Step 3:
20 divided by 3 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 96.0
If we take 18 away from 20, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

Step 4:
When dividing 21 by 3, we get 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 967.0
Subtracting 21 from 21 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 3

Going ahead to step 5:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 9671.0
Subtracting 3 from 3 leaves us with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 3

Going ahead to step 6:
4 divided by 3 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 96711.0
If we take 3 away from 4, 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 7:
10 divided by 3 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 96711.3
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.

Step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 96711.33
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.

After the division, we end up with 96711.33 and a remainder of 0.001.
