Let's divide 642647 by 80
Let's see how many times 80 fits into 642647.

On to step 1:
When dividing 6 by 80, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 80

On to step 2:
64 divided by 80 is 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 80

Moving on to step 3:
If we divide 642 by 80, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 640 from 642 leaves us with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 80

On to step 4:
80 goes into 26 0 times with a remainder of 26.
The next digit of our result is 0. 
Result so far: 80.0
The remainder is 26 after subtracting 0 from 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 80

Let's proceed to step 5:
80 can be fit into 264 3 times, resulting in a remainder of 24.
The next digit of our result is 3. 
Result so far: 803.0
If we take 240 away from 264, we end up with 24.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 80

Advancing to step 6:
80 goes into 247 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 8033.0
If we subtract 240 from 247, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
70 divided by 80 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 8033.0
Subtracting 0 from 70 leaves us 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 8:
If we divide 700 by 80, we get 8 and a remainder of 60.
The next digit of our result is 8. 
Result so far: 8033.08
Subtract 640 from 700 to get 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 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 8033.087
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.

Let's proceed to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8033.0875
If we take 400 away from 400, 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 11:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8033.0875
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.

Let's proceed to 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: 8033.0875
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 8033.0875, and the remainder is 0.0.
