13185 divided by 3 
The aim is to understand the frequency of 3 in 13185.

Going ahead to step 1:
3 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 3

Step 2:
If we divide 13 by 3, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 1 after subtracting 12 from 13.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 3

Advancing to step 3:
11 divided by 3 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 43.0
Subtracting 9 from 11 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 3

Going ahead to step 4:
If we divide 28 by 3, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 439.0
Subtracting 27 from 28 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Step 5:
When dividing 15 by 3, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 4395.0
If we subtract 15 from 15, 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 6:
3 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4395.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
If we divide 0 by 3, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4395.0
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.

Our division results in 4395.0 with a remaining 0.0.
