66583 ÷ 80 
Let's see how many times 80 fits into 66583.

Going ahead to step 1:
When dividing 6 by 80, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 80

Moving on to step 2:
66 divided by 80 is 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (5) from the dividend, add it to 66, then carry on: 665 / 80

Going ahead to step 3:
The number 80 fits into 665 8 times, leaving a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 640 from 665 to get 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 80

Moving on to step 4:
If we divide 258 by 80, we get 3 and a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 83.0
Subtracting 240 from 258 leaves us with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 80

Step 5:
80 can be fit into 183 2 times, resulting in a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 832.0
Subtract 160 from 183 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 6:
80 can be fit into 230 2 times, resulting in a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 832.2
If we subtract 160 from 230, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 7:
80 goes into 700 8 times with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 832.28
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.

Step 8:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 832.287
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.

Going ahead to step 9:
80 goes into 400 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 832.2875
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.

Moving on to step 10:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 832.2875
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.

Advancing to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 832.2875
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.

The quotient of the division is 832.2875, and the remainder is 0.0.
