2959065 ÷ 780 
The aim is to understand the frequency of 780 in 2959065.

Let's proceed to step 1:
780 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 780

On to step 2:
The number 780 fits into 29 0 times, leaving a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 780

Advancing to step 3:
When dividing 295 by 780, we get 0 with a remainder of 295.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 295 after subtracting 0 from 295.
Grab the next digit (9) from the dividend, add it to 295, then carry on: 2959 / 780

Let's proceed to step 4:
The number 780 fits into 2959 3 times, leaving a remainder of 619.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 2340 from 2959 to get 619.
Take the next digit (0) from the dividend and append it to 619, then repeat: 6190 / 780

Advancing to step 5:
780 can be fit into 6190 7 times, resulting in a remainder of 730.
The next digit of our result is 7. 
Result so far: 37.0
The remainder is 730 after subtracting 5460 from 6190.
Take the next digit (6) from the dividend and append it to 730, then repeat: 7306 / 780

Moving on to step 6:
When dividing 7306 by 780, we get 9 with a remainder of 286.
Record the quotient 9 as the next digit in the result. 
Result so far: 379.0
Deduct 7020 from 7306 and we're left with 286.
Bring next digit (5) of the dividend behind the 286 and repeat the process: 2865 / 780

On to step 7:
780 goes into 2865 3 times with a remainder of 525.
Put 3 as the next digit of the answer. 
Result so far: 3793.0
If we take 2340 away from 2865, we end up with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Let's proceed to step 8:
780 can be fit into 5250 6 times, resulting in a remainder of 570.
The number 6 becomes the next digit in our result. 
Result so far: 3793.6
The remainder is 570 after subtracting 4680 from 5250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 9:
5700 divided by 780 is 7 with a remainder of 240.
The next digit of our result is 7. 
Result so far: 3793.67
If we take 5460 away from 5700, we end up 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 10:
780 can be fit into 2400 3 times, resulting in a remainder of 60.
The next digit of our result is 3. 
Result so far: 3793.673
Subtract 2340 from 2400 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.

Let's proceed to step 11:
780 can be fit into 600 0 times, resulting in a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 3793.673
If we subtract 0 from 600, we get 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 12:
When dividing 6000 by 780, we get 7 with a remainder of 540.
Record the quotient 7 as the next digit in the result. 
Result so far: 3793.67307
If we subtract 5460 from 6000, we 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.

Moving on to step 13:
780 can be fit into 5400 6 times, resulting in a remainder of 720.
The next digit of our result is 6. 
Result so far: 3793.673076
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.

Moving on to step 14:
780 can be fit into 7200 9 times, resulting in a remainder of 180.
Write down 9 as next digit of the result. 
Result so far: 3793.6730769
If we take 7020 away from 7200, we end up 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.

On to step 15:
1800 divided by 780 is 2 with a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 3793.67307692
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.

After the division, we end up with 3793.67307692 and a remainder of 2.4e-07.
