We look at the division of 638184 by 80 
We want to figure out the number of times 638184 can be divided by 80.

Let's proceed to step 1:
The number 80 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 80

Step 2:
80 goes into 63 0 times with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 80

Step 3:
When dividing 638 by 80, we get 7 with a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 560 from 638 leaves us with 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 80

Let's proceed to step 4:
The number 80 fits into 781 9 times, leaving a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtract 720 from 781 to get 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 80

On to step 5:
The number 80 fits into 618 7 times, leaving a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 797.0
If we subtract 560 from 618, we get 58.
Bring next digit (4) of the dividend behind the 58 and repeat the process: 584 / 80

Step 6:
The number 80 fits into 584 7 times, leaving a remainder of 24.
The next digit of our result is 7. 
Result so far: 7977.0
Subtracting 560 from 584 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
If we divide 240 by 80, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 7977.3
Deduct 240 from 240 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.

Let's proceed to step 8:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7977.3
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.

Going ahead to step 9:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7977.3
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 7977.3, and the remainder is 0.0.
