We divide 82308021 by 312
The aim is to understand the frequency of 312 in 82308021.

Advancing to step 1:
312 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 312

Advancing to step 2:
The number 312 fits into 82 0 times, leaving a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Append the next digit (3) from the dividend to 82 and continue with: 823 / 312

Let's proceed to step 3:
312 can be fit into 823 2 times, resulting in a remainder of 199.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 624 from 823 and we're left with 199.
Take the next digit (0) from the dividend and append it to 199, then repeat: 1990 / 312

Moving on to step 4:
If we divide 1990 by 312, we get 6 and a remainder of 118.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we take 1872 away from 1990, we end up with 118.
Append the next digit (8) from the dividend to 118 and continue with: 1188 / 312

Step 5:
The number 312 fits into 1188 3 times, leaving a remainder of 252.
Put 3 as the next digit of the answer. 
Result so far: 263.0
If we subtract 936 from 1188, we get 252.
Grab the next digit (0) from the dividend, add it to 252, then carry on: 2520 / 312

Going ahead to step 6:
If we divide 2520 by 312, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 2638.0
If we take 2496 away from 2520, we end up with 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 312

Step 7:
The number 312 fits into 242 0 times, leaving a remainder of 242.
Use 0 as the next digit of our solution. 
Result so far: 26380.0
If we take 0 away from 242, we end up with 242.
Take the next digit (1) from the dividend and append it to 242, then repeat: 2421 / 312

Going ahead to step 8:
The number 312 fits into 2421 7 times, leaving a remainder of 237.
Put 7 as the next digit of the answer. 
Result so far: 263807.0
Subtract 2184 from 2421 to get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 9:
When dividing 2370 by 312, we get 7 with a remainder of 186.
The next digit of our result is 7. 
Result so far: 263807.7
If we take 2184 away from 2370, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 10:
When dividing 1860 by 312, we get 5 with a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 263807.75
If we take 1560 away from 1860, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 11:
The number 312 fits into 3000 9 times, leaving a remainder of 192.
Write down 9 as next digit of the result. 
Result so far: 263807.759
The remainder is 192 after subtracting 2808 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 12:
The number 312 fits into 1920 6 times, leaving a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 263807.7596
Subtracting 1872 from 1920 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
312 goes into 480 1 times with a remainder of 168.
Put 1 as the next digit of the answer. 
Result so far: 263807.75961
If we subtract 312 from 480, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 14:
1680 divided by 312 is 5 with a remainder of 120.
Put 5 as the next digit of the answer. 
Result so far: 263807.759615
If we subtract 1560 from 1680, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 15:
If we divide 1200 by 312, we get 3 and a remainder of 264.
Record the quotient 3 as the next digit in the result. 
Result so far: 263807.7596153
Subtract 936 from 1200 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 16:
The number 312 fits into 2640 8 times, leaving a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 263807.75961538
Deduct 2496 from 2640 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The quotient of the division is 263807.75961538, and the remainder is 1.44e-07.
