We look at the division of 20207256 by 690 
The aim is to understand the frequency of 690 in 20207256.

Advancing to step 1:
690 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 690

Moving on to step 2:
20 divided by 690 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 690

Let's proceed to step 3:
690 can be fit into 202 0 times, resulting in a remainder of 202.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 202, we end up with 202.
Take the next digit (0) from the dividend and append it to 202, then repeat: 2020 / 690

Let's proceed to step 4:
2020 divided by 690 is 2 with a remainder of 640.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1380 from 2020 to get 640.
Grab the next digit (7) from the dividend, add it to 640, then carry on: 6407 / 690

Going ahead to step 5:
If we divide 6407 by 690, we get 9 and a remainder of 197.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 6210 from 6407 to get 197.
Fetch the next digit (2) from the dividend, attach it to 197 and continue: 1972 / 690

On to step 6:
When dividing 1972 by 690, we get 2 with a remainder of 592.
Use 2 as the next digit of our solution. 
Result so far: 292.0
If we subtract 1380 from 1972, we get 592.
Append the next digit (5) from the dividend to 592 and continue with: 5925 / 690

Let's proceed to step 7:
If we divide 5925 by 690, we get 8 and a remainder of 405.
The number 8 becomes the next digit in our result. 
Result so far: 2928.0
Subtract 5520 from 5925 to get 405.
Fetch the next digit (6) from the dividend, attach it to 405 and continue: 4056 / 690

On to step 8:
When dividing 4056 by 690, we get 5 with a remainder of 606.
Record the quotient 5 as the next digit in the result. 
Result so far: 29285.0
Subtract 3450 from 4056 to get 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Advancing to step 9:
690 can be fit into 6060 8 times, resulting in a remainder of 540.
The number 8 becomes the next digit in our result. 
Result so far: 29285.8
Deduct 5520 from 6060 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 10:
The number 690 fits into 5400 7 times, leaving a remainder of 570.
Write down 7 as next digit of the result. 
Result so far: 29285.87
If we subtract 4830 from 5400, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 11:
When dividing 5700 by 690, we get 8 with a remainder of 180.
Put 8 as the next digit of the answer. 
Result so far: 29285.878
Subtracting 5520 from 5700 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 12:
690 goes into 1800 2 times with a remainder of 420.
Write down 2 as next digit of the result. 
Result so far: 29285.8782
If we take 1380 away from 1800, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 13:
If we divide 4200 by 690, we get 6 and a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 29285.87826
Deduct 4140 from 4200 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
690 goes into 600 0 times with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 29285.87826
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 15:
690 goes into 6000 8 times with a remainder of 480.
The next digit of our result is 8. 
Result so far: 29285.8782608
If we subtract 5520 from 6000, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 16:
690 goes into 4800 6 times with a remainder of 660.
Use 6 as the next digit of our solution. 
Result so far: 29285.87826086
The remainder is 660 after subtracting 4140 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Our division results in 29285.87826086 with a remaining 6.6e-07.
