We're dividing 908600 by 3 
The aim is to understand the frequency of 3 in 908600.

Moving on to step 1:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 9 away from 9, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 3

Moving on to step 2:
3 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 3

Let's proceed to step 3:
The number 3 fits into 8 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 302.0
Subtract 6 from 8 to get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 3

Step 4:
The number 3 fits into 26 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 3028.0
If we subtract 24 from 26, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 3

Going ahead to step 5:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 30286.0
Subtract 18 from 20 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 3

Going ahead to step 6:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 302866.0
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.

On to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 302866.6
Deduct 18 from 20 and we're left 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.

On to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 302866.66
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.

In conclusion, the division gives 302866.66 with a balance of 0.002.
