We divide 80362497 by 312
The aim is to understand the frequency of 312 in 80362497.

On to step 1:
If we divide 8 by 312, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 312

Step 2:
When dividing 80 by 312, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (3) of the dividend behind the 80 and repeat the process: 803 / 312

Step 3:
312 can be fit into 803 2 times, resulting in a remainder of 179.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 624 from 803, we get 179.
Bring next digit (6) of the dividend behind the 179 and repeat the process: 1796 / 312

Moving on to step 4:
312 goes into 1796 5 times with a remainder of 236.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 236 after subtracting 1560 from 1796.
Grab the next digit (2) from the dividend, add it to 236, then carry on: 2362 / 312

Advancing to step 5:
312 can be fit into 2362 7 times, resulting in a remainder of 178.
Record the quotient 7 as the next digit in the result. 
Result so far: 257.0
Subtract 2184 from 2362 to get 178.
Bring next digit (4) of the dividend behind the 178 and repeat the process: 1784 / 312

Moving on to step 6:
312 can be fit into 1784 5 times, resulting in a remainder of 224.
The number 5 becomes the next digit in our result. 
Result so far: 2575.0
Deduct 1560 from 1784 and we're left with 224.
Append the next digit (9) from the dividend to 224 and continue with: 2249 / 312

Step 7:
2249 divided by 312 is 7 with a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 25757.0
Subtract 2184 from 2249 to get 65.
Bring next digit (7) of the dividend behind the 65 and repeat the process: 657 / 312

On to step 8:
The number 312 fits into 657 2 times, leaving a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 257572.0
Subtracting 624 from 657 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
330 divided by 312 is 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 257572.1
Subtracting 312 from 330 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
180 divided by 312 is 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 257572.1
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
When dividing 1800 by 312, we get 5 with a remainder of 240.
Write down 5 as next digit of the result. 
Result so far: 257572.105
If we subtract 1560 from 1800, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 12:
When dividing 2400 by 312, we get 7 with a remainder of 216.
Use 7 as the next digit of our solution. 
Result so far: 257572.1057
If we take 2184 away from 2400, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 13:
2160 divided by 312 is 6 with a remainder of 288.
Record the quotient 6 as the next digit in the result. 
Result so far: 257572.10576
If we subtract 1872 from 2160, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 14:
2880 divided by 312 is 9 with a remainder of 72.
The next digit of our result is 9. 
Result so far: 257572.105769
Deduct 2808 from 2880 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 15:
312 can be fit into 720 2 times, resulting in a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 257572.1057692
If we subtract 624 from 720, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 16:
312 goes into 960 3 times with a remainder of 24.
The next digit of our result is 3. 
Result so far: 257572.10576923
The remainder is 24 after subtracting 936 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 257572.10576923 with a balance of 2.4e-08.
