Let's divide 28809409 by 312
The aim is to understand the frequency of 312 in 28809409.

Let's proceed to step 1:
The number 312 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 312

Moving on to step 2:
312 goes into 28 0 times with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 312

Step 3:
288 divided by 312 is 0 with a remainder of 288.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 288 leaves us with 288.
Take the next digit (0) from the dividend and append it to 288, then repeat: 2880 / 312

On to step 4:
312 goes into 2880 9 times with a remainder of 72.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 2808 from 2880 and we're left with 72.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 312

Step 5:
312 goes into 729 2 times with a remainder of 105.
Use 2 as the next digit of our solution. 
Result so far: 92.0
Subtract 624 from 729 to get 105.
Bring next digit (4) of the dividend behind the 105 and repeat the process: 1054 / 312

Let's proceed to step 6:
When dividing 1054 by 312, we get 3 with a remainder of 118.
Record the quotient 3 as the next digit in the result. 
Result so far: 923.0
Subtract 936 from 1054 to get 118.
Grab the next digit (0) from the dividend, add it to 118, then carry on: 1180 / 312

Let's proceed to step 7:
The number 312 fits into 1180 3 times, leaving a remainder of 244.
Record the quotient 3 as the next digit in the result. 
Result so far: 9233.0
Subtract 936 from 1180 to get 244.
Append the next digit (9) from the dividend to 244 and continue with: 2449 / 312

Going ahead to step 8:
2449 divided by 312 is 7 with a remainder of 265.
Use 7 as the next digit of our solution. 
Result so far: 92337.0
If we subtract 2184 from 2449, we get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 9:
312 goes into 2650 8 times with a remainder of 154.
Put 8 as the next digit of the answer. 
Result so far: 92337.8
The remainder is 154 after subtracting 2496 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 10:
1540 divided by 312 is 4 with a remainder of 292.
Record the quotient 4 as the next digit in the result. 
Result so far: 92337.84
If we take 1248 away from 1540, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 11:
If we divide 2920 by 312, we get 9 and a remainder of 112.
The number 9 becomes the next digit in our result. 
Result so far: 92337.849
If we take 2808 away from 2920, we end up 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.

Advancing to step 12:
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: 92337.8493
Subtract 936 from 1120 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 13:
312 goes into 1840 5 times with a remainder of 280.
Record the quotient 5 as the next digit in the result. 
Result so far: 92337.84935
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.

Advancing to step 14:
If we divide 2800 by 312, we get 8 and a remainder of 304.
Write down 8 as next digit of the result. 
Result so far: 92337.849358
Subtract 2496 from 2800 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 15:
If we divide 3040 by 312, we get 9 and a remainder of 232.
Record the quotient 9 as the next digit in the result. 
Result so far: 92337.8493589
Deduct 2808 from 3040 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 16:
312 goes into 2320 7 times with a remainder of 136.
The number 7 becomes the next digit in our result. 
Result so far: 92337.84935897
If we subtract 2184 from 2320, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The quotient of the division is 92337.84935897, and the remainder is 1.36e-07.
