We're dividing 476343 by 30 
The aim is to understand the frequency of 30 in 476343.

Step 1:
When dividing 4 by 30, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 30

Moving on to step 2:
47 divided by 30 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 17 after subtracting 30 from 47.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 30

On to step 3:
30 can be fit into 176 5 times, resulting in a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 26 after subtracting 150 from 176.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 30

Step 4:
30 can be fit into 263 8 times, resulting in a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 158.0
If we subtract 240 from 263, we get 23.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 30

Going ahead to step 5:
When dividing 234 by 30, we get 7 with a remainder of 24.
The next digit of our result is 7. 
Result so far: 1587.0
If we subtract 210 from 234, we get 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 30

Moving on to step 6:
30 goes into 243 8 times with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 15878.0
The remainder is 3 after subtracting 240 from 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
When dividing 30 by 30, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 15878.1
Subtract 30 from 30 to 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 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15878.1
Deduct 0 from 0 and we're left with 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 9:
30 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15878.1
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.

The final result is 15878.1 with a remainder of 0.0.
