We look at the division of 19610 by 3 
The aim is to understand the frequency of 3 in 19610.

Moving on to step 1:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 3

Moving on to step 2:
When dividing 19 by 3, we get 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 18 away from 19, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 3

Advancing to step 3:
When dividing 16 by 3, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
The remainder is 1 after subtracting 15 from 16.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 3

Going ahead to step 4:
11 divided by 3 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 653.0
Deduct 9 from 11 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 3

Advancing to step 5:
If we divide 20 by 3, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 6536.0
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 6:
3 goes into 20 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 6536.6
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 6536.66
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 6536.66, and the remainder is 0.002.
