20777798 divided by 689 
The aim is to understand the frequency of 689 in 20777798.

Advancing to step 1:
The number 689 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 689

Let's proceed to step 2:
689 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 689

On to step 3:
If we divide 207 by 689, we get 0 and a remainder of 207.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 207 and we're left with 207.
Take the next digit (7) from the dividend and append it to 207, then repeat: 2077 / 689

Advancing to step 4:
The number 689 fits into 2077 3 times, leaving a remainder of 10.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2067 from 2077, we get 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 689

Advancing to step 5:
689 goes into 107 0 times with a remainder of 107.
Use 0 as the next digit of our solution. 
Result so far: 30.0
The remainder is 107 after subtracting 0 from 107.
Take the next digit (7) from the dividend and append it to 107, then repeat: 1077 / 689

Let's proceed to step 6:
The number 689 fits into 1077 1 times, leaving a remainder of 388.
The number 1 becomes the next digit in our result. 
Result so far: 301.0
The remainder is 388 after subtracting 689 from 1077.
Grab the next digit (9) from the dividend, add it to 388, then carry on: 3889 / 689

Let's proceed to step 7:
When dividing 3889 by 689, we get 5 with a remainder of 444.
The number 5 becomes the next digit in our result. 
Result so far: 3015.0
Subtracting 3445 from 3889 leaves us with 444.
Take the next digit (8) from the dividend and append it to 444, then repeat: 4448 / 689

Going ahead to step 8:
If we divide 4448 by 689, we get 6 and a remainder of 314.
Record the quotient 6 as the next digit in the result. 
Result so far: 30156.0
Deduct 4134 from 4448 and we're left with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 9:
When dividing 3140 by 689, we get 4 with a remainder of 384.
Use 4 as the next digit of our solution. 
Result so far: 30156.4
Subtracting 2756 from 3140 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 10:
If we divide 3840 by 689, we get 5 and a remainder of 395.
Write down 5 as next digit of the result. 
Result so far: 30156.45
If we take 3445 away from 3840, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Let's proceed to step 11:
3950 divided by 689 is 5 with a remainder of 505.
The next digit of our result is 5. 
Result so far: 30156.455
Subtracting 3445 from 3950 leaves us with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

In conclusion, the division gives 30156.455 with a balance of 0.0505.
