90810216 divided by 272 
The aim is to understand the frequency of 272 in 90810216.

Step 1:
272 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 272

On to step 2:
The number 272 fits into 90 0 times, leaving a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Bring next digit (8) of the dividend behind the 90 and repeat the process: 908 / 272

Advancing to step 3:
272 goes into 908 3 times with a remainder of 92.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 816 from 908 leaves us with 92.
Grab the next digit (1) from the dividend, add it to 92, then carry on: 921 / 272

Advancing to step 4:
272 can be fit into 921 3 times, resulting in a remainder of 105.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
The remainder is 105 after subtracting 816 from 921.
Include the next digit (0) from the dividend after 105, then repeat: 1050 / 272

Advancing to step 5:
The number 272 fits into 1050 3 times, leaving a remainder of 234.
The number 3 becomes the next digit in our result. 
Result so far: 333.0
If we take 816 away from 1050, we end up with 234.
Append the next digit (2) from the dividend to 234 and continue with: 2342 / 272

Let's proceed to step 6:
The number 272 fits into 2342 8 times, leaving a remainder of 166.
The number 8 becomes the next digit in our result. 
Result so far: 3338.0
If we take 2176 away from 2342, we end up with 166.
Take the next digit (1) from the dividend and append it to 166, then repeat: 1661 / 272

Step 7:
The number 272 fits into 1661 6 times, leaving a remainder of 29.
The next digit of our result is 6. 
Result so far: 33386.0
If we subtract 1632 from 1661, we get 29.
Take the next digit (6) from the dividend and append it to 29, then repeat: 296 / 272

On to step 8:
The number 272 fits into 296 1 times, leaving a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 333861.0
If we take 272 away from 296, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
The number 272 fits into 240 0 times, leaving a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 333861.0
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 10:
272 can be fit into 2400 8 times, resulting in a remainder of 224.
Put 8 as the next digit of the answer. 
Result so far: 333861.08
Subtract 2176 from 2400 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 11:
The number 272 fits into 2240 8 times, leaving a remainder of 64.
The next digit of our result is 8. 
Result so far: 333861.088
If we take 2176 away from 2240, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 333861.088 and a remainder of 0.0064.
