We're dividing 20798013 by 768 
The aim is to understand the frequency of 768 in 20798013.

Going ahead to step 1:
If we divide 2 by 768, we get 0 and 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.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 768

Going ahead to step 2:
The number 768 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 768

Going ahead to step 3:
207 divided by 768 is 0 with a remainder of 207.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 207 to get 207.
Bring next digit (9) of the dividend behind the 207 and repeat the process: 2079 / 768

Let's proceed to step 4:
2079 divided by 768 is 2 with a remainder of 543.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 1536 from 2079 leaves us with 543.
Include the next digit (8) from the dividend after 543, then repeat: 5438 / 768

Moving on to step 5:
768 goes into 5438 7 times with a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we take 5376 away from 5438, we end up with 62.
Fetch the next digit (0) from the dividend, attach it to 62 and continue: 620 / 768

On to step 6:
768 can be fit into 620 0 times, resulting in a remainder of 620.
Use 0 as the next digit of our solution. 
Result so far: 270.0
If we take 0 away from 620, we end up with 620.
Grab the next digit (1) from the dividend, add it to 620, then carry on: 6201 / 768

Advancing to step 7:
768 can be fit into 6201 8 times, resulting in a remainder of 57.
The next digit of our result is 8. 
Result so far: 2708.0
Subtract 6144 from 6201 to get 57.
Append the next digit (3) from the dividend to 57 and continue with: 573 / 768

Moving on to step 8:
768 goes into 573 0 times with a remainder of 573.
Record the quotient 0 as the next digit in the result. 
Result so far: 27080.0
Subtract 0 from 573 to get 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Let's proceed to step 9:
When dividing 5730 by 768, we get 7 with a remainder of 354.
The next digit of our result is 7. 
Result so far: 27080.7
Subtracting 5376 from 5730 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 10:
When dividing 3540 by 768, we get 4 with a remainder of 468.
Record the quotient 4 as the next digit in the result. 
Result so far: 27080.74
The remainder is 468 after subtracting 3072 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Going ahead to step 11:
If we divide 4680 by 768, we get 6 and a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 27080.746
Subtracting 4608 from 4680 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
The number 768 fits into 720 0 times, leaving a remainder of 720.
Record the quotient 0 as the next digit in the result. 
Result so far: 27080.746
Subtracting 0 from 720 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 13:
768 can be fit into 7200 9 times, resulting in a remainder of 288.
Use 9 as the next digit of our solution. 
Result so far: 27080.74609
Subtract 6912 from 7200 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 14:
768 goes into 2880 3 times with a remainder of 576.
Write down 3 as next digit of the result. 
Result so far: 27080.746093
Subtract 2304 from 2880 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 15:
5760 divided by 768 is 7 with a remainder of 384.
Put 7 as the next digit of the answer. 
Result so far: 27080.7460937
Subtracting 5376 from 5760 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.

Advancing to step 16:
768 goes into 3840 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 27080.74609375
Subtract 3840 from 3840 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 27080.74609375 and a remainder of 0.0.
