772083 divided by 78 
The aim is to understand the frequency of 78 in 772083.

Let's proceed to step 1:
If we divide 7 by 78, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 78

Let's proceed to step 2:
78 goes into 77 0 times with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Fetch the next digit (2) from the dividend, attach it to 77 and continue: 772 / 78

Going ahead to step 3:
772 divided by 78 is 9 with a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 702 from 772 and we're left with 70.
Append the next digit (0) from the dividend to 70 and continue with: 700 / 78

Step 4:
78 goes into 700 8 times with a remainder of 76.
The next digit of our result is 8. 
Result so far: 98.0
If we subtract 624 from 700, we get 76.
Include the next digit (8) from the dividend after 76, then repeat: 768 / 78

Advancing to step 5:
When dividing 768 by 78, we get 9 with a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 989.0
Subtracting 702 from 768 leaves us with 66.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 78

Advancing to step 6:
78 goes into 663 8 times with a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 9898.0
Deduct 624 from 663 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
If we divide 390 by 78, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 9898.5
If we take 390 away from 390, 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.

Going ahead to step 8:
If we divide 0 by 78, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 9898.5
The remainder is 0 after subtracting 0 from 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:
78 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9898.5
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 outcome is 9898.5, with a leftover of 0.0.
