We're dividing 977586 by 80 
We want to figure out the number of times 977586 can be divided by 80.

Going ahead to step 1:
The number 80 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 80

Let's proceed to step 2:
When dividing 97 by 80, we get 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 80 from 97, we get 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 80

Advancing to step 3:
80 goes into 177 2 times with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 160 from 177 to get 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 80

Going ahead to step 4:
If we divide 175 by 80, we get 2 and a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 122.0
Deduct 160 from 175 and we're left with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 80

Let's proceed to step 5:
The number 80 fits into 158 1 times, leaving a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 1221.0
If we take 80 away from 158, we end up with 78.
Take the next digit (6) from the dividend and append it to 78, then repeat: 786 / 80

Advancing to step 6:
80 can be fit into 786 9 times, resulting in a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 12219.0
Subtract 720 from 786 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
80 can be fit into 660 8 times, resulting in a remainder of 20.
The next digit of our result is 8. 
Result so far: 12219.8
Subtract 640 from 660 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
The number 80 fits into 200 2 times, leaving a remainder of 40.
The next digit of our result is 2. 
Result so far: 12219.82
If we subtract 160 from 200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
80 goes into 400 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 12219.825
Subtract 400 from 400 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.

Step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12219.825
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.

Advancing to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12219.825
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.

After the division, we end up with 12219.825 and a remainder of 0.0.
