619294 ÷ 30 
The aim is to understand the frequency of 30 in 619294.

Step 1:
30 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 30

Step 2:
When dividing 61 by 30, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 60 from 61 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 30

Step 3:
When dividing 19 by 30, we get 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 30

Moving on to step 4:
When dividing 192 by 30, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 206.0
Subtracting 180 from 192 leaves us with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 30

Let's proceed to step 5:
30 can be fit into 129 4 times, resulting in a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 2064.0
Subtract 120 from 129 to get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 30

Let's proceed to step 6:
When dividing 94 by 30, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 20643.0
If we take 90 away from 94, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
30 goes into 40 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 20643.1
Deduct 30 from 40 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.

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: 20643.13
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.

Let's proceed to step 9:
If we divide 100 by 30, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 20643.133
Subtracting 90 from 100 leaves us 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.

The final outcome is 20643.133, with a leftover of 0.001.
