We're dividing 80101744 by 312 
The aim is to understand the frequency of 312 in 80101744.

Step 1:
When dividing 8 by 312, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 312

On to step 2:
312 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 312

Step 3:
801 divided by 312 is 2 with a remainder of 177.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 177 after subtracting 624 from 801.
Include the next digit (0) from the dividend after 177, then repeat: 1770 / 312

Going ahead to step 4:
1770 divided by 312 is 5 with a remainder of 210.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 1560 away from 1770, we end up with 210.
Take the next digit (1) from the dividend and append it to 210, then repeat: 2101 / 312

Let's proceed to step 5:
The number 312 fits into 2101 6 times, leaving a remainder of 229.
The number 6 becomes the next digit in our result. 
Result so far: 256.0
If we subtract 1872 from 2101, we get 229.
Take the next digit (7) from the dividend and append it to 229, then repeat: 2297 / 312

Moving on to step 6:
If we divide 2297 by 312, we get 7 and a remainder of 113.
Use 7 as the next digit of our solution. 
Result so far: 2567.0
If we take 2184 away from 2297, we end up with 113.
Grab the next digit (4) from the dividend, add it to 113, then carry on: 1134 / 312

Let's proceed to step 7:
312 can be fit into 1134 3 times, resulting in a remainder of 198.
The number 3 becomes the next digit in our result. 
Result so far: 25673.0
Deduct 936 from 1134 and we're left with 198.
Grab the next digit (4) from the dividend, add it to 198, then carry on: 1984 / 312

Moving on to step 8:
The number 312 fits into 1984 6 times, leaving a remainder of 112.
The next digit of our result is 6. 
Result so far: 256736.0
Deduct 1872 from 1984 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 9:
If we divide 1120 by 312, we get 3 and a remainder of 184.
The next digit of our result is 3. 
Result so far: 256736.3
The remainder is 184 after subtracting 936 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 10:
1840 divided by 312 is 5 with a remainder of 280.
Put 5 as the next digit of the answer. 
Result so far: 256736.35
Subtracting 1560 from 1840 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 11:
If we divide 2800 by 312, we get 8 and a remainder of 304.
Use 8 as the next digit of our solution. 
Result so far: 256736.358
If we take 2496 away from 2800, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 12:
3040 divided by 312 is 9 with a remainder of 232.
The next digit of our result is 9. 
Result so far: 256736.3589
If we subtract 2808 from 3040, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 13:
312 goes into 2320 7 times with a remainder of 136.
Write down 7 as next digit of the result. 
Result so far: 256736.35897
The remainder is 136 after subtracting 2184 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 14:
312 can be fit into 1360 4 times, resulting in a remainder of 112.
Write down 4 as next digit of the result. 
Result so far: 256736.358974
Subtract 1248 from 1360 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 15:
The number 312 fits into 1120 3 times, leaving a remainder of 184.
Write down 3 as next digit of the result. 
Result so far: 256736.3589743
Subtracting 936 from 1120 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 16:
The number 312 fits into 1840 5 times, leaving a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 256736.35897435
If we subtract 1560 from 1840, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final result is 256736.35897435 with a remainder of 2.8e-07.
