Let's divide 83010900 by 311
The aim is to understand the frequency of 311 in 83010900.

Let's proceed to step 1:
When dividing 8 by 311, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 311

On to step 2:
The number 311 fits into 83 0 times, leaving a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Include the next digit (0) from the dividend after 83, then repeat: 830 / 311

Going ahead to step 3:
If we divide 830 by 311, we get 2 and a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 622 from 830 and we're left with 208.
Take the next digit (1) from the dividend and append it to 208, then repeat: 2081 / 311

Going ahead to step 4:
When dividing 2081 by 311, we get 6 with a remainder of 215.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we subtract 1866 from 2081, we get 215.
Fetch the next digit (0) from the dividend, attach it to 215 and continue: 2150 / 311

Let's proceed to step 5:
311 can be fit into 2150 6 times, resulting in a remainder of 284.
Write down 6 as next digit of the result. 
Result so far: 266.0
Deduct 1866 from 2150 and we're left with 284.
Append the next digit (9) from the dividend to 284 and continue with: 2849 / 311

Let's proceed to step 6:
311 can be fit into 2849 9 times, resulting in a remainder of 50.
Use 9 as the next digit of our solution. 
Result so far: 2669.0
Deduct 2799 from 2849 and we're left with 50.
Grab the next digit (0) from the dividend, add it to 50, then carry on: 500 / 311

Moving on to step 7:
When dividing 500 by 311, we get 1 with a remainder of 189.
Record the quotient 1 as the next digit in the result. 
Result so far: 26691.0
Deduct 311 from 500 and we're left with 189.
Include the next digit (0) from the dividend after 189, then repeat: 1890 / 311

Let's proceed to step 8:
311 can be fit into 1890 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 266916.0
Subtract 1866 from 1890 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
311 goes into 240 0 times with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 266916.0
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 10:
The number 311 fits into 2400 7 times, leaving a remainder of 223.
Use 7 as the next digit of our solution. 
Result so far: 266916.07
Subtract 2177 from 2400 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 11:
When dividing 2230 by 311, we get 7 with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 266916.077
If we subtract 2177 from 2230, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final outcome is 266916.077, with a leftover of 0.0053.
