We look at the division of 20082773 by 312 
The aim is to understand the frequency of 312 in 20082773.

Advancing to step 1:
2 divided by 312 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 312

Advancing to step 2:
312 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 312

Moving on to step 3:
200 divided by 312 is 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 200, we end up with 200.
Fetch the next digit (8) from the dividend, attach it to 200 and continue: 2008 / 312

On to step 4:
If we divide 2008 by 312, we get 6 and a remainder of 136.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 1872 from 2008 leaves us with 136.
Bring next digit (2) of the dividend behind the 136 and repeat the process: 1362 / 312

Moving on to step 5:
1362 divided by 312 is 4 with a remainder of 114.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Deduct 1248 from 1362 and we're left with 114.
Take the next digit (7) from the dividend and append it to 114, then repeat: 1147 / 312

Step 6:
When dividing 1147 by 312, we get 3 with a remainder of 211.
The number 3 becomes the next digit in our result. 
Result so far: 643.0
Subtract 936 from 1147 to get 211.
Grab the next digit (7) from the dividend, add it to 211, then carry on: 2117 / 312

Moving on to step 7:
2117 divided by 312 is 6 with a remainder of 245.
Use 6 as the next digit of our solution. 
Result so far: 6436.0
Deduct 1872 from 2117 and we're left with 245.
Take the next digit (3) from the dividend and append it to 245, then repeat: 2453 / 312

Advancing to step 8:
2453 divided by 312 is 7 with a remainder of 269.
Put 7 as the next digit of the answer. 
Result so far: 64367.0
If we take 2184 away from 2453, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

On to step 9:
2690 divided by 312 is 8 with a remainder of 194.
Put 8 as the next digit of the answer. 
Result so far: 64367.8
The remainder is 194 after subtracting 2496 from 2690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 10:
1940 divided by 312 is 6 with a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 64367.86
Deduct 1872 from 1940 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 11:
680 divided by 312 is 2 with a remainder of 56.
The next digit of our result is 2. 
Result so far: 64367.862
If we subtract 624 from 680, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 12:
When dividing 560 by 312, we get 1 with a remainder of 248.
Write down 1 as next digit of the result. 
Result so far: 64367.8621
Deduct 312 from 560 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 13:
2480 divided by 312 is 7 with a remainder of 296.
Record the quotient 7 as the next digit in the result. 
Result so far: 64367.86217
Subtracting 2184 from 2480 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 14:
When dividing 2960 by 312, we get 9 with a remainder of 152.
The number 9 becomes the next digit in our result. 
Result so far: 64367.862179
Subtract 2808 from 2960 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 15:
When dividing 1520 by 312, we get 4 with a remainder of 272.
Use 4 as the next digit of our solution. 
Result so far: 64367.8621794
The remainder is 272 after subtracting 1248 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 16:
312 can be fit into 2720 8 times, resulting in a remainder of 224.
Record the quotient 8 as the next digit in the result. 
Result so far: 64367.86217948
If we subtract 2496 from 2720, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final result is 64367.86217948 with a remainder of 2.24e-07.
