3927035 ÷ 780 
The aim is to understand the frequency of 780 in 3927035.

Let's proceed to step 1:
3 divided by 780 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 780

Let's proceed to step 2:
When dividing 39 by 780, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 780

Advancing to step 3:
When dividing 392 by 780, we get 0 with a remainder of 392.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 392, we end up with 392.
Grab the next digit (7) from the dividend, add it to 392, then carry on: 3927 / 780

On to step 4:
When dividing 3927 by 780, we get 5 with a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 3900 from 3927 to get 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 780

Advancing to step 5:
780 goes into 270 0 times with a remainder of 270.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Subtract 0 from 270 to get 270.
Take the next digit (3) from the dividend and append it to 270, then repeat: 2703 / 780

Let's proceed to step 6:
780 can be fit into 2703 3 times, resulting in a remainder of 363.
Use 3 as the next digit of our solution. 
Result so far: 503.0
Deduct 2340 from 2703 and we're left with 363.
Take the next digit (5) from the dividend and append it to 363, then repeat: 3635 / 780

Moving on to step 7:
The number 780 fits into 3635 4 times, leaving a remainder of 515.
The number 4 becomes the next digit in our result. 
Result so far: 5034.0
If we subtract 3120 from 3635, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Going ahead to step 8:
780 can be fit into 5150 6 times, resulting in a remainder of 470.
The next digit of our result is 6. 
Result so far: 5034.6
If we subtract 4680 from 5150, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 9:
If we divide 4700 by 780, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 5034.66
If we subtract 4680 from 4700, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 5034.66, with a leftover of 0.02.
