We divide 624103 by 30
The aim is to understand the frequency of 30 in 624103.

Going ahead to step 1:
30 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 30

On to step 2:
The number 30 fits into 62 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 60 from 62, we get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 30

Step 3:
30 goes into 24 0 times with a remainder of 24.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 24, we end up with 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 30

Advancing to step 4:
When dividing 241 by 30, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 208.0
Deduct 240 from 241 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 30

Going ahead to step 5:
10 divided by 30 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 2080.0
If we take 0 away from 10, we end up with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 30

Going ahead to step 6:
103 divided by 30 is 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 20803.0
Deduct 90 from 103 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
If we divide 130 by 30, we get 4 and a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 20803.4
If we subtract 120 from 130, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
The next digit of our result is 3. 
Result so far: 20803.43
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
30 goes into 100 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 20803.433
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 20803.433 and a remainder of 0.001.
