We're dividing 67826720 by 310 
The aim is to understand the frequency of 310 in 67826720.

Advancing to step 1:
6 divided by 310 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 310

On to step 2:
67 divided by 310 is 0 with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 310

Advancing to step 3:
678 divided by 310 is 2 with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 620 from 678, we get 58.
Grab the next digit (2) from the dividend, add it to 58, then carry on: 582 / 310

Going ahead to step 4:
310 goes into 582 1 times with a remainder of 272.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 310 from 582 to get 272.
Bring next digit (6) of the dividend behind the 272 and repeat the process: 2726 / 310

Let's proceed to step 5:
310 goes into 2726 8 times with a remainder of 246.
The number 8 becomes the next digit in our result. 
Result so far: 218.0
If we take 2480 away from 2726, we end up with 246.
Append the next digit (7) from the dividend to 246 and continue with: 2467 / 310

On to step 6:
310 can be fit into 2467 7 times, resulting in a remainder of 297.
Write down 7 as next digit of the result. 
Result so far: 2187.0
Subtract 2170 from 2467 to get 297.
Include the next digit (2) from the dividend after 297, then repeat: 2972 / 310

Moving on to step 7:
310 can be fit into 2972 9 times, resulting in a remainder of 182.
Use 9 as the next digit of our solution. 
Result so far: 21879.0
If we subtract 2790 from 2972, we get 182.
Include the next digit (0) from the dividend after 182, then repeat: 1820 / 310

Advancing to step 8:
310 goes into 1820 5 times with a remainder of 270.
Write down 5 as next digit of the result. 
Result so far: 218795.0
If we subtract 1550 from 1820, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 9:
310 goes into 2700 8 times with a remainder of 220.
Write down 8 as next digit of the result. 
Result so far: 218795.8
The remainder is 220 after subtracting 2480 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 10:
If we divide 2200 by 310, we get 7 and a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 218795.87
If we take 2170 away from 2200, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
When dividing 300 by 310, we get 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 218795.87
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 12:
310 goes into 3000 9 times with a remainder of 210.
The next digit of our result is 9. 
Result so far: 218795.8709
If we subtract 2790 from 3000, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 13:
310 goes into 2100 6 times with a remainder of 240.
Use 6 as the next digit of our solution. 
Result so far: 218795.87096
Subtract 1860 from 2100 to 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.

Step 14:
310 goes into 2400 7 times with a remainder of 230.
The number 7 becomes the next digit in our result. 
Result so far: 218795.870967
The remainder is 230 after subtracting 2170 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 15:
The number 310 fits into 2300 7 times, leaving a remainder of 130.
Record the quotient 7 as the next digit in the result. 
Result so far: 218795.8709677
Deduct 2170 from 2300 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final result is 218795.8709677 with a remainder of 1.3e-06.
