We look at the division of 75654738 by 30 
The aim is to understand the frequency of 30 in 75654738.

Moving on to step 1:
30 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 30

Going ahead to step 2:
30 can be fit into 75 2 times, resulting in a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 60 from 75 and we're left with 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 30

On to step 3:
The number 30 fits into 156 5 times, leaving a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Deduct 150 from 156 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 30

Step 4:
65 divided by 30 is 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 252.0
Subtract 60 from 65 to get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 30

Going ahead to step 5:
30 can be fit into 54 1 times, resulting in a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 2521.0
Subtracting 30 from 54 leaves us with 24.
Grab the next digit (7) from the dividend, add it to 24, then carry on: 247 / 30

Going ahead to step 6:
The number 30 fits into 247 8 times, leaving a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 25218.0
Subtracting 240 from 247 leaves us with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 30

Advancing to step 7:
When dividing 73 by 30, we get 2 with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 252182.0
If we subtract 60 from 73, we get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 30

Moving on to step 8:
30 goes into 138 4 times with a remainder of 18.
The next digit of our result is 4. 
Result so far: 2521824.0
If we take 120 away from 138, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
180 divided by 30 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 2521824.6
Deduct 180 from 180 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.

Step 10:
If we divide 0 by 30, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2521824.6
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.

On to step 11:
When dividing 0 by 30, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2521824.6
Subtracting 0 from 0 leaves us 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.

The final result is 2521824.6 with a remainder of 0.0.
