28726674 divided by 331 
The aim is to understand the frequency of 331 in 28726674.

Going ahead to step 1:
The number 331 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 331

Moving on to step 2:
331 goes into 28 0 times with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 331

Moving on to step 3:
287 divided by 331 is 0 with a remainder of 287.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 287 leaves us with 287.
Fetch the next digit (2) from the dividend, attach it to 287 and continue: 2872 / 331

Advancing to step 4:
The number 331 fits into 2872 8 times, leaving a remainder of 224.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 2648 from 2872 leaves us with 224.
Grab the next digit (6) from the dividend, add it to 224, then carry on: 2246 / 331

Let's proceed to step 5:
331 can be fit into 2246 6 times, resulting in a remainder of 260.
Put 6 as the next digit of the answer. 
Result so far: 86.0
If we take 1986 away from 2246, we end up with 260.
Bring next digit (6) of the dividend behind the 260 and repeat the process: 2606 / 331

Step 6:
331 goes into 2606 7 times with a remainder of 289.
Put 7 as the next digit of the answer. 
Result so far: 867.0
Subtract 2317 from 2606 to get 289.
Fetch the next digit (7) from the dividend, attach it to 289 and continue: 2897 / 331

Moving on to step 7:
331 goes into 2897 8 times with a remainder of 249.
Put 8 as the next digit of the answer. 
Result so far: 8678.0
The remainder is 249 after subtracting 2648 from 2897.
Fetch the next digit (4) from the dividend, attach it to 249 and continue: 2494 / 331

Going ahead to step 8:
331 can be fit into 2494 7 times, resulting in a remainder of 177.
Put 7 as the next digit of the answer. 
Result so far: 86787.0
If we take 2317 away from 2494, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 9:
331 can be fit into 1770 5 times, resulting in a remainder of 115.
The next digit of our result is 5. 
Result so far: 86787.5
Deduct 1655 from 1770 and we're left 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.

On to step 10:
331 can be fit into 1150 3 times, resulting in a remainder of 157.
Put 3 as the next digit of the answer. 
Result so far: 86787.53
If we take 993 away from 1150, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 11:
1570 divided by 331 is 4 with a remainder of 246.
Use 4 as the next digit of our solution. 
Result so far: 86787.534
If we take 1324 away from 1570, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 12:
331 goes into 2460 7 times with a remainder of 143.
Put 7 as the next digit of the answer. 
Result so far: 86787.5347
Subtracting 2317 from 2460 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Advancing to step 13:
When dividing 1430 by 331, we get 4 with a remainder of 106.
Put 4 as the next digit of the answer. 
Result so far: 86787.53474
If we subtract 1324 from 1430, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 14:
When dividing 1060 by 331, we get 3 with a remainder of 67.
The next digit of our result is 3. 
Result so far: 86787.534743
The remainder is 67 after subtracting 993 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 15:
The number 331 fits into 670 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 86787.5347432
Deduct 662 from 670 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 16:
331 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 86787.5347432
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 86787.5347432 with a remainder of 8e-08.
