We look at the division of 15918050 by 80 
We want to divide 15918050 by 80.

Let's proceed to step 1:
80 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 80

Advancing to step 2:
80 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 80

Let's proceed to step 3:
80 can be fit into 159 1 times, resulting in a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 80 from 159 leaves us with 79.
Include the next digit (1) from the dividend after 79, then repeat: 791 / 80

Going ahead to step 4:
791 divided by 80 is 9 with a remainder of 71.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 720 from 791 and we're left with 71.
Grab the next digit (8) from the dividend, add it to 71, then carry on: 718 / 80

Let's proceed to step 5:
718 divided by 80 is 8 with a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 198.0
Subtract 640 from 718 to get 78.
Grab the next digit (0) from the dividend, add it to 78, then carry on: 780 / 80

Going ahead to step 6:
80 goes into 780 9 times with a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 1989.0
If we take 720 away from 780, we end up with 60.
Append the next digit (5) from the dividend to 60 and continue with: 605 / 80

Going ahead to step 7:
When dividing 605 by 80, we get 7 with a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 19897.0
Subtract 560 from 605 to get 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 80

Step 8:
80 can be fit into 450 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 198975.0
If we subtract 400 from 450, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
If we divide 500 by 80, we get 6 and a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 198975.6
Subtracting 480 from 500 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
80 goes into 200 2 times with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 198975.62
Subtracting 160 from 200 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 11:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 198975.625
Deduct 400 from 400 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 12:
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: 198975.625
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.

Moving on to step 13:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 198975.625
Subtracting 0 from 0 leaves us 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 final outcome is 198975.625, with a leftover of 0.0.
