We divide 640110 by 30
The aim is to understand the frequency of 30 in 640110.

Advancing to step 1:
When dividing 6 by 30, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 30

On to step 2:
If we divide 64 by 30, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 4 after subtracting 60 from 64.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 30

Going ahead to step 3:
30 can be fit into 40 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 30 from 40 to get 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 30

Step 4:
30 goes into 101 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 213.0
If we take 90 away from 101, we end up with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 30

Let's proceed to step 5:
30 can be fit into 111 3 times, resulting in a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 2133.0
Subtracting 90 from 111 leaves us with 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 30

Step 6:
30 can be fit into 210 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 21337.0
If we take 210 away from 210, we end up 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 7:
When dividing 0 by 30, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21337.0
If we subtract 0 from 0, we 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.

Let's proceed to step 8:
If we divide 0 by 30, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 21337.0
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.

In conclusion, the division gives 21337.0 with a balance of 0.0.
