676594 ÷ 780 
The aim is to understand the frequency of 780 in 676594.

Going ahead to step 1:
780 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 780

On to step 2:
780 goes into 67 0 times with a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Grab the next digit (6) from the dividend, add it to 67, then carry on: 676 / 780

Going ahead to step 3:
The number 780 fits into 676 0 times, leaving a remainder of 676.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 676 leaves us with 676.
Grab the next digit (5) from the dividend, add it to 676, then carry on: 6765 / 780

Step 4:
If we divide 6765 by 780, we get 8 and a remainder of 525.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 6240 from 6765 to get 525.
Take the next digit (9) from the dividend and append it to 525, then repeat: 5259 / 780

Advancing to step 5:
780 goes into 5259 6 times with a remainder of 579.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we subtract 4680 from 5259, we get 579.
Take the next digit (4) from the dividend and append it to 579, then repeat: 5794 / 780

Step 6:
If we divide 5794 by 780, we get 7 and a remainder of 334.
Write down 7 as next digit of the result. 
Result so far: 867.0
The remainder is 334 after subtracting 5460 from 5794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 7:
If we divide 3340 by 780, we get 4 and a remainder of 220.
Use 4 as the next digit of our solution. 
Result so far: 867.4
If we take 3120 away from 3340, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 8:
When dividing 2200 by 780, we get 2 with a remainder of 640.
The next digit of our result is 2. 
Result so far: 867.42
If we take 1560 away from 2200, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 9:
If we divide 6400 by 780, we get 8 and a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 867.428
If we take 6240 away from 6400, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 10:
If we divide 1600 by 780, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 867.4282
Deduct 1560 from 1600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
When dividing 400 by 780, we get 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 867.4282
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 12:
4000 divided by 780 is 5 with a remainder of 100.
The next digit of our result is 5. 
Result so far: 867.428205
Subtract 3900 from 4000 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 13:
780 can be fit into 1000 1 times, resulting in a remainder of 220.
Write down 1 as next digit of the result. 
Result so far: 867.4282051
If we take 780 away from 1000, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 14:
If we divide 2200 by 780, we get 2 and a remainder of 640.
Write down 2 as next digit of the result. 
Result so far: 867.42820512
Deduct 1560 from 2200 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

In conclusion, the division gives 867.42820512 with a balance of 6.4e-07.
