Let's divide 220475 by 30
The aim is to understand the frequency of 30 in 220475.

Advancing to step 1:
If we divide 2 by 30, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 30

Let's proceed to step 2:
The number 30 fits into 22 0 times, leaving a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 30

Moving on to step 3:
The number 30 fits into 220 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 210 from 220 leaves us with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 30

Let's proceed to step 4:
104 divided by 30 is 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Subtract 90 from 104 to get 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 30

Going ahead to step 5:
The number 30 fits into 147 4 times, leaving a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 734.0
Subtract 120 from 147 to get 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 30

On to step 6:
30 can be fit into 275 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 7349.0
Subtract 270 from 275 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
The number 30 fits into 50 1 times, leaving a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 7349.1
Subtract 30 from 50 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 7349.16
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 7349.166
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 7349.166 with a remainder of 0.002.
