We're dividing 74578369 by 311 
The aim is to understand the frequency of 311 in 74578369.

Step 1:
7 divided by 311 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 311

Let's proceed to step 2:
The number 311 fits into 74 0 times, leaving a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Take the next digit (5) from the dividend and append it to 74, then repeat: 745 / 311

Let's proceed to step 3:
When dividing 745 by 311, we get 2 with a remainder of 123.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 123 after subtracting 622 from 745.
Include the next digit (7) from the dividend after 123, then repeat: 1237 / 311

Moving on to step 4:
311 can be fit into 1237 3 times, resulting in a remainder of 304.
Write down 3 as next digit of the result. 
Result so far: 23.0
The remainder is 304 after subtracting 933 from 1237.
Fetch the next digit (8) from the dividend, attach it to 304 and continue: 3048 / 311

Let's proceed to step 5:
The number 311 fits into 3048 9 times, leaving a remainder of 249.
The next digit of our result is 9. 
Result so far: 239.0
Deduct 2799 from 3048 and we're left with 249.
Append the next digit (3) from the dividend to 249 and continue with: 2493 / 311

Step 6:
311 can be fit into 2493 8 times, resulting in a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 2398.0
The remainder is 5 after subtracting 2488 from 2493.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 311

Step 7:
When dividing 56 by 311, we get 0 with a remainder of 56.
The next digit of our result is 0. 
Result so far: 23980.0
If we subtract 0 from 56, we get 56.
Include the next digit (9) from the dividend after 56, then repeat: 569 / 311

Step 8:
If we divide 569 by 311, we get 1 and a remainder of 258.
The next digit of our result is 1. 
Result so far: 239801.0
Subtracting 311 from 569 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 9:
The number 311 fits into 2580 8 times, leaving a remainder of 92.
Put 8 as the next digit of the answer. 
Result so far: 239801.8
The remainder is 92 after subtracting 2488 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 10:
The number 311 fits into 920 2 times, leaving a remainder of 298.
Put 2 as the next digit of the answer. 
Result so far: 239801.82
Subtracting 622 from 920 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 11:
311 can be fit into 2980 9 times, resulting in a remainder of 181.
Write down 9 as next digit of the result. 
Result so far: 239801.829
Deduct 2799 from 2980 and we're left with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Going ahead to step 12:
The number 311 fits into 1810 5 times, leaving a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 239801.8295
If we take 1555 away from 1810, 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.

Let's proceed to step 13:
When dividing 2550 by 311, we get 8 with a remainder of 62.
The next digit of our result is 8. 
Result so far: 239801.82958
Subtracting 2488 from 2550 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 14:
311 goes into 620 1 times with a remainder of 309.
The number 1 becomes the next digit in our result. 
Result so far: 239801.829581
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.

Advancing to step 15:
311 can be fit into 3090 9 times, resulting in a remainder of 291.
The number 9 becomes the next digit in our result. 
Result so far: 239801.8295819
If we take 2799 away from 3090, we end up 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.

Going ahead to step 16:
2910 divided by 311 is 9 with a remainder of 111.
The number 9 becomes the next digit in our result. 
Result so far: 239801.82958199
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.

After the division, we end up with 239801.82958199 and a remainder of 1.11e-07.
