Let's divide 51028824 by 311
The aim is to understand the frequency of 311 in 51028824.

Advancing to step 1:
If we divide 5 by 311, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 311

Let's proceed to step 2:
If we divide 51 by 311, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 311

Advancing to step 3:
The number 311 fits into 510 1 times, leaving a remainder of 199.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 311 away from 510, we end up with 199.
Include the next digit (2) from the dividend after 199, then repeat: 1992 / 311

On to step 4:
When dividing 1992 by 311, we get 6 with a remainder of 126.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 126 after subtracting 1866 from 1992.
Bring next digit (8) of the dividend behind the 126 and repeat the process: 1268 / 311

Going ahead to step 5:
1268 divided by 311 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
Subtracting 1244 from 1268 leaves us with 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 311

On to step 6:
The number 311 fits into 248 0 times, leaving a remainder of 248.
The number 0 becomes the next digit in our result. 
Result so far: 1640.0
If we take 0 away from 248, we end up with 248.
Bring next digit (2) of the dividend behind the 248 and repeat the process: 2482 / 311

Step 7:
When dividing 2482 by 311, we get 7 with a remainder of 305.
Write down 7 as next digit of the result. 
Result so far: 16407.0
Subtract 2177 from 2482 to get 305.
Include the next digit (4) from the dividend after 305, then repeat: 3054 / 311

Advancing to step 8:
311 can be fit into 3054 9 times, resulting in a remainder of 255.
The number 9 becomes the next digit in our result. 
Result so far: 164079.0
If we take 2799 away from 3054, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Advancing to step 9:
The number 311 fits into 2550 8 times, leaving a remainder of 62.
The next digit of our result is 8. 
Result so far: 164079.8
If we subtract 2488 from 2550, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
311 can be fit into 620 1 times, resulting in a remainder of 309.
The number 1 becomes the next digit in our result. 
Result so far: 164079.81
Deduct 311 from 620 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 11:
311 can be fit into 3090 9 times, resulting in a remainder of 291.
Write down 9 as next digit of the result. 
Result so far: 164079.819
Deduct 2799 from 3090 and we're left with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Advancing to step 12:
311 can be fit into 2910 9 times, resulting in a remainder of 111.
The next digit of our result is 9. 
Result so far: 164079.8199
If we subtract 2799 from 2910, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

The final outcome is 164079.8199, with a leftover of 0.00111.
