Let's divide 66458638 by 311
The aim is to understand the frequency of 311 in 66458638.

Moving on to step 1:
If we divide 6 by 311, we get 0 and 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.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 311

Moving on to step 2:
When dividing 66 by 311, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Take the next digit (4) from the dividend and append it to 66, then repeat: 664 / 311

Going ahead to step 3:
311 can be fit into 664 2 times, resulting in a remainder of 42.
The next digit of our result is 2. 
Result so far: 2.0
If we take 622 away from 664, we end up with 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 311

Step 4:
425 divided by 311 is 1 with a remainder of 114.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 311 away from 425, we end up with 114.
Append the next digit (8) from the dividend to 114 and continue with: 1148 / 311

Advancing to step 5:
When dividing 1148 by 311, we get 3 with a remainder of 215.
Write down 3 as next digit of the result. 
Result so far: 213.0
If we subtract 933 from 1148, we get 215.
Take the next digit (6) from the dividend and append it to 215, then repeat: 2156 / 311

Let's proceed to step 6:
When dividing 2156 by 311, we get 6 with a remainder of 290.
Put 6 as the next digit of the answer. 
Result so far: 2136.0
Subtracting 1866 from 2156 leaves us with 290.
Include the next digit (3) from the dividend after 290, then repeat: 2903 / 311

Step 7:
When dividing 2903 by 311, we get 9 with a remainder of 104.
Use 9 as the next digit of our solution. 
Result so far: 21369.0
If we subtract 2799 from 2903, we get 104.
Fetch the next digit (8) from the dividend, attach it to 104 and continue: 1048 / 311

Let's proceed to step 8:
1048 divided by 311 is 3 with a remainder of 115.
Record the quotient 3 as the next digit in the result. 
Result so far: 213693.0
If we take 933 away from 1048, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 9:
The number 311 fits into 1150 3 times, leaving a remainder of 217.
The next digit of our result is 3. 
Result so far: 213693.3
The remainder is 217 after subtracting 933 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Advancing to step 10:
2170 divided by 311 is 6 with a remainder of 304.
The next digit of our result is 6. 
Result so far: 213693.36
The remainder is 304 after subtracting 1866 from 2170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 11:
When dividing 3040 by 311, we get 9 with a remainder of 241.
Use 9 as the next digit of our solution. 
Result so far: 213693.369
Subtract 2799 from 3040 to get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Let's proceed to step 12:
If we divide 2410 by 311, we get 7 and a remainder of 233.
Record the quotient 7 as the next digit in the result. 
Result so far: 213693.3697
Deduct 2177 from 2410 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Going ahead to step 13:
The number 311 fits into 2330 7 times, leaving a remainder of 153.
The next digit of our result is 7. 
Result so far: 213693.36977
The remainder is 153 after subtracting 2177 from 2330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

After the division, we end up with 213693.36977 and a remainder of 0.000153.
