We're dividing 14615781 by 780 
The aim is to understand the frequency of 780 in 14615781.

Let's proceed to step 1:
If we divide 1 by 780, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 780

On to step 2:
The number 780 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 780

Moving on to step 3:
780 goes into 146 0 times with a remainder of 146.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 146 to get 146.
Append the next digit (1) from the dividend to 146 and continue with: 1461 / 780

On to step 4:
1461 divided by 780 is 1 with a remainder of 681.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 780 from 1461 leaves us with 681.
Bring next digit (5) of the dividend behind the 681 and repeat the process: 6815 / 780

Moving on to step 5:
780 can be fit into 6815 8 times, resulting in a remainder of 575.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 6240 from 6815 and we're left with 575.
Append the next digit (7) from the dividend to 575 and continue with: 5757 / 780

Advancing to step 6:
The number 780 fits into 5757 7 times, leaving a remainder of 297.
The next digit of our result is 7. 
Result so far: 187.0
If we subtract 5460 from 5757, we get 297.
Fetch the next digit (8) from the dividend, attach it to 297 and continue: 2978 / 780

Advancing to step 7:
When dividing 2978 by 780, we get 3 with a remainder of 638.
Write down 3 as next digit of the result. 
Result so far: 1873.0
Deduct 2340 from 2978 and we're left with 638.
Include the next digit (1) from the dividend after 638, then repeat: 6381 / 780

Let's proceed to step 8:
780 can be fit into 6381 8 times, resulting in a remainder of 141.
Put 8 as the next digit of the answer. 
Result so far: 18738.0
The remainder is 141 after subtracting 6240 from 6381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 9:
1410 divided by 780 is 1 with a remainder of 630.
Record the quotient 1 as the next digit in the result. 
Result so far: 18738.1
The remainder is 630 after subtracting 780 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Let's proceed to step 10:
The number 780 fits into 6300 8 times, leaving a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 18738.18
Subtract 6240 from 6300 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
600 divided by 780 is 0 with a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 18738.18
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 12:
780 goes into 6000 7 times with a remainder of 540.
Write down 7 as next digit of the result. 
Result so far: 18738.1807
If we take 5460 away from 6000, we end up 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.

Let's proceed to step 13:
780 goes into 5400 6 times with a remainder of 720.
The number 6 becomes the next digit in our result. 
Result so far: 18738.18076
Deduct 4680 from 5400 and we're left 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 14:
780 goes into 7200 9 times with a remainder of 180.
Put 9 as the next digit of the answer. 
Result so far: 18738.180769
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.

Going ahead to step 15:
The number 780 fits into 1800 2 times, leaving a remainder of 240.
The next digit of our result is 2. 
Result so far: 18738.1807692
Subtract 1560 from 1800 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 16:
780 can be fit into 2400 3 times, resulting in a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 18738.18076923
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.

After the division, we end up with 18738.18076923 and a remainder of 6e-08.
