786070 divided by 80 
The aim is to understand the frequency of 80 in 786070.

Advancing to step 1:
80 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 80

Let's proceed to step 2:
80 goes into 78 0 times with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 80

Advancing to step 3:
80 can be fit into 786 9 times, resulting in a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 720 from 786 and we're left with 66.
Include the next digit (0) from the dividend after 66, then repeat: 660 / 80

Going ahead to step 4:
80 can be fit into 660 8 times, resulting in a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 98.0
Deduct 640 from 660 and we're left with 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 80

Going ahead to step 5:
The number 80 fits into 207 2 times, leaving a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 982.0
Deduct 160 from 207 and we're left with 47.
Bring next digit (0) of the dividend behind the 47 and repeat the process: 470 / 80

Moving on to step 6:
80 goes into 470 5 times with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 9825.0
Deduct 400 from 470 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
80 can be fit into 700 8 times, resulting in a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 9825.8
Deduct 640 from 700 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
When dividing 600 by 80, we get 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 9825.87
Subtracting 560 from 600 leaves us 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.

Advancing to step 9:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 9825.875
Deduct 400 from 400 and we're left 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.

On to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9825.875
Deduct 0 from 0 and we're left 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.

On to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9825.875
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 9825.875, with a leftover of 0.0.
