69697680 ÷ 780 
The aim is to understand the frequency of 780 in 69697680.

Advancing to step 1:
When dividing 6 by 780, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 780

Let's proceed to step 2:
780 goes into 69 0 times with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Take the next digit (6) from the dividend and append it to 69, then repeat: 696 / 780

On to step 3:
When dividing 696 by 780, we get 0 with a remainder of 696.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 696, we get 696.
Bring next digit (9) of the dividend behind the 696 and repeat the process: 6969 / 780

Moving on to step 4:
When dividing 6969 by 780, we get 8 with a remainder of 729.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 6240 from 6969 leaves us with 729.
Grab the next digit (7) from the dividend, add it to 729, then carry on: 7297 / 780

Advancing to step 5:
7297 divided by 780 is 9 with a remainder of 277.
Use 9 as the next digit of our solution. 
Result so far: 89.0
The remainder is 277 after subtracting 7020 from 7297.
Grab the next digit (6) from the dividend, add it to 277, then carry on: 2776 / 780

Going ahead to step 6:
2776 divided by 780 is 3 with a remainder of 436.
Record the quotient 3 as the next digit in the result. 
Result so far: 893.0
Subtracting 2340 from 2776 leaves us with 436.
Grab the next digit (8) from the dividend, add it to 436, then carry on: 4368 / 780

Going ahead to step 7:
780 can be fit into 4368 5 times, resulting in a remainder of 468.
The number 5 becomes the next digit in our result. 
Result so far: 8935.0
If we subtract 3900 from 4368, we get 468.
Include the next digit (0) from the dividend after 468, then repeat: 4680 / 780

On to step 8:
The number 780 fits into 4680 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 89356.0
If we take 4680 away from 4680, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
780 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 89356.0
If we subtract 0 from 0, we 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.

Going ahead to step 10:
If we divide 0 by 780, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 89356.0
Subtract 0 from 0 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.

The final result is 89356.0 with a remainder of 0.0.
