We're dividing 987571 by 80 
Let's see how many times 80 fits into 987571.

Moving on to step 1:
80 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 80

Moving on to step 2:
98 divided by 80 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 80 from 98 and we're left with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 80

Let's proceed to step 3:
80 goes into 187 2 times with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 160 from 187 and we're left with 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 80

On to step 4:
The number 80 fits into 275 3 times, leaving a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Deduct 240 from 275 and we're left with 35.
Include the next digit (7) from the dividend after 35, then repeat: 357 / 80

Advancing to step 5:
80 goes into 357 4 times with a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 1234.0
The remainder is 37 after subtracting 320 from 357.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 80

Going ahead to step 6:
If we divide 371 by 80, we get 4 and a remainder of 51.
The number 4 becomes the next digit in our result. 
Result so far: 12344.0
If we take 320 away from 371, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
The number 80 fits into 510 6 times, leaving a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 12344.6
Subtracting 480 from 510 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
300 divided by 80 is 3 with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 12344.63
Deduct 240 from 300 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.

Let's proceed to step 9:
80 goes into 600 7 times with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 12344.637
If we subtract 560 from 600, 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.

Advancing to step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 12344.6375
The remainder is 0 after subtracting 400 from 400.
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.
Put 0 as the next digit of the answer. 
Result so far: 12344.6375
If we subtract 0 from 0, we 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 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12344.6375
If we take 0 away from 0, 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.

The quotient of the division is 12344.6375, and the remainder is 0.0.
