We look at the division of 20841918 by 314 
The aim is to understand the frequency of 314 in 20841918.

Advancing to step 1:
314 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 314

On to step 2:
314 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 314

Step 3:
208 divided by 314 is 0 with a remainder of 208.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 208 and we're left with 208.
Grab the next digit (4) from the dividend, add it to 208, then carry on: 2084 / 314

Moving on to step 4:
2084 divided by 314 is 6 with a remainder of 200.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 1884 away from 2084, we end up with 200.
Include the next digit (1) from the dividend after 200, then repeat: 2001 / 314

Going ahead to step 5:
The number 314 fits into 2001 6 times, leaving a remainder of 117.
Write down 6 as next digit of the result. 
Result so far: 66.0
Deduct 1884 from 2001 and we're left with 117.
Append the next digit (9) from the dividend to 117 and continue with: 1179 / 314

Advancing to step 6:
If we divide 1179 by 314, we get 3 and a remainder of 237.
Record the quotient 3 as the next digit in the result. 
Result so far: 663.0
Deduct 942 from 1179 and we're left with 237.
Append the next digit (1) from the dividend to 237 and continue with: 2371 / 314

Moving on to step 7:
314 goes into 2371 7 times with a remainder of 173.
The next digit of our result is 7. 
Result so far: 6637.0
If we subtract 2198 from 2371, we get 173.
Fetch the next digit (8) from the dividend, attach it to 173 and continue: 1738 / 314

Moving on to step 8:
The number 314 fits into 1738 5 times, leaving a remainder of 168.
Put 5 as the next digit of the answer. 
Result so far: 66375.0
Subtracting 1570 from 1738 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 9:
If we divide 1680 by 314, we get 5 and a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 66375.5
Subtract 1570 from 1680 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
The number 314 fits into 1100 3 times, leaving a remainder of 158.
Record the quotient 3 as the next digit in the result. 
Result so far: 66375.53
If we take 942 away from 1100, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 11:
314 can be fit into 1580 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 66375.535
Subtracting 1570 from 1580 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
314 can be fit into 100 0 times, resulting in a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 66375.535
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 13:
If we divide 1000 by 314, we get 3 and a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 66375.53503
The remainder is 58 after subtracting 942 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 14:
The number 314 fits into 580 1 times, leaving a remainder of 266.
Record the quotient 1 as the next digit in the result. 
Result so far: 66375.535031
Deduct 314 from 580 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 15:
2660 divided by 314 is 8 with a remainder of 148.
Put 8 as the next digit of the answer. 
Result so far: 66375.5350318
The remainder is 148 after subtracting 2512 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 16:
When dividing 1480 by 314, we get 4 with a remainder of 224.
Put 4 as the next digit of the answer. 
Result so far: 66375.53503184
If we take 1256 away from 1480, we end up with 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 66375.53503184 with a remainder of 2.24e-07.
