We're dividing 860498 by 3 
The aim is to understand the frequency of 3 in 860498.

Moving on to step 1:
3 can be fit into 8 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
If we take 6 away from 8, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 3

On to step 2:
The number 3 fits into 26 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 28.0
Deduct 24 from 26 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 3

Step 3:
When dividing 20 by 3, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 286.0
If we subtract 18 from 20, we get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 3

Going ahead to step 4:
3 goes into 24 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 2868.0
If we subtract 24 from 24, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 3

On to step 5:
3 goes into 9 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 28683.0
If we take 9 away from 9, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

Advancing to step 6:
8 divided by 3 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 286832.0
The remainder is 2 after subtracting 6 from 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
20 divided by 3 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 286832.6
If we take 18 away from 20, we end up 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.

Step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 286832.66
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 286832.66, and the remainder is 0.002.
