We look at the division of 81716180 by 780 
The aim is to understand the frequency of 780 in 81716180.

Step 1:
780 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 780

Advancing to step 2:
The number 780 fits into 81 0 times, leaving a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 780

Moving on to step 3:
The number 780 fits into 817 1 times, leaving a remainder of 37.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 780 from 817 leaves us with 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 780

Advancing to step 4:
780 can be fit into 371 0 times, resulting in a remainder of 371.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 371 and we're left with 371.
Bring next digit (6) of the dividend behind the 371 and repeat the process: 3716 / 780

Let's proceed to step 5:
When dividing 3716 by 780, we get 4 with a remainder of 596.
Use 4 as the next digit of our solution. 
Result so far: 104.0
If we subtract 3120 from 3716, we get 596.
Append the next digit (1) from the dividend to 596 and continue with: 5961 / 780

Advancing to step 6:
780 can be fit into 5961 7 times, resulting in a remainder of 501.
Use 7 as the next digit of our solution. 
Result so far: 1047.0
Deduct 5460 from 5961 and we're left with 501.
Fetch the next digit (8) from the dividend, attach it to 501 and continue: 5018 / 780

Let's proceed to step 7:
780 can be fit into 5018 6 times, resulting in a remainder of 338.
Record the quotient 6 as the next digit in the result. 
Result so far: 10476.0
Deduct 4680 from 5018 and we're left with 338.
Take the next digit (0) from the dividend and append it to 338, then repeat: 3380 / 780

Going ahead to step 8:
When dividing 3380 by 780, we get 4 with a remainder of 260.
Use 4 as the next digit of our solution. 
Result so far: 104764.0
If we take 3120 away from 3380, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 9:
780 can be fit into 2600 3 times, resulting in a remainder of 260.
The number 3 becomes the next digit in our result. 
Result so far: 104764.3
If we subtract 2340 from 2600, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 10:
780 goes into 2600 3 times with a remainder of 260.
Write down 3 as next digit of the result. 
Result so far: 104764.33
If we take 2340 away from 2600, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

In conclusion, the division gives 104764.33 with a balance of 0.26.
