We look at the division of 10929927 by 780 
The aim is to understand the frequency of 780 in 10929927.

Step 1:
When dividing 1 by 780, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 780

On to step 2:
780 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 780

Let's proceed to step 3:
780 goes into 109 0 times with a remainder of 109.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 109 after subtracting 0 from 109.
Grab the next digit (2) from the dividend, add it to 109, then carry on: 1092 / 780

Let's proceed to step 4:
1092 divided by 780 is 1 with a remainder of 312.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 780 away from 1092, we end up with 312.
Include the next digit (9) from the dividend after 312, then repeat: 3129 / 780

Going ahead to step 5:
When dividing 3129 by 780, we get 4 with a remainder of 9.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 9 after subtracting 3120 from 3129.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 780

Going ahead to step 6:
When dividing 99 by 780, we get 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
Deduct 0 from 99 and we're left with 99.
Include the next digit (2) from the dividend after 99, then repeat: 992 / 780

Step 7:
If we divide 992 by 780, we get 1 and a remainder of 212.
Write down 1 as next digit of the result. 
Result so far: 1401.0
If we subtract 780 from 992, we get 212.
Take the next digit (7) from the dividend and append it to 212, then repeat: 2127 / 780

Step 8:
When dividing 2127 by 780, we get 2 with a remainder of 567.
The next digit of our result is 2. 
Result so far: 14012.0
If we take 1560 away from 2127, we end up with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Advancing to step 9:
If we divide 5670 by 780, we get 7 and a remainder of 210.
The next digit of our result is 7. 
Result so far: 14012.7
If we take 5460 away from 5670, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 10:
2100 divided by 780 is 2 with a remainder of 540.
The number 2 becomes the next digit in our result. 
Result so far: 14012.72
Deduct 1560 from 2100 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.

Advancing to step 11:
780 goes into 5400 6 times with a remainder of 720.
Write down 6 as next digit of the result. 
Result so far: 14012.726
Subtracting 4680 from 5400 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.

Going ahead to step 12:
If we divide 7200 by 780, we get 9 and a remainder of 180.
Record the quotient 9 as the next digit in the result. 
Result so far: 14012.7269
Subtracting 7020 from 7200 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 13:
When dividing 1800 by 780, we get 2 with a remainder of 240.
The next digit of our result is 2. 
Result so far: 14012.72692
Subtracting 1560 from 1800 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 14:
780 can be fit into 2400 3 times, resulting in a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 14012.726923
If we take 2340 away from 2400, we end up 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.

Advancing to step 15:
When dividing 600 by 780, we get 0 with a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 14012.726923
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 16:
780 goes into 6000 7 times with a remainder of 540.
The next digit of our result is 7. 
Result so far: 14012.72692307
Subtract 5460 from 6000 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

After the division, we end up with 14012.72692307 and a remainder of 5.4e-07.
