We're dividing 307820 by 9 
The aim is to understand the frequency of 9 in 307820.

Moving on to step 1:
9 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 9

Step 2:
If we divide 30 by 9, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 27 from 30, we get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 9

Moving on to step 3:
If we divide 37 by 9, we get 4 and a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 34.0
Deduct 36 from 37 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 9

Moving on to step 4:
When dividing 18 by 9, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 342.0
The remainder is 0 after subtracting 18 from 18.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 9

Step 5:
9 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 3420.0
If we subtract 0 from 2, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 9

Moving on to step 6:
9 can be fit into 20 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 34202.0
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:
20 divided by 9 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 34202.2
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
20 divided by 9 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 34202.22
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.

The quotient of the division is 34202.22, and the remainder is 0.002.
