142893 divided by 80 
Let's see how many times 80 fits into 142893.

On to step 1:
1 divided by 80 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 80

Going ahead to step 2:
80 goes into 14 0 times with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 80

On to step 3:
The number 80 fits into 142 1 times, leaving a remainder of 62.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 80 from 142 leaves us with 62.
Fetch the next digit (8) from the dividend, attach it to 62 and continue: 628 / 80

Step 4:
80 goes into 628 7 times with a remainder of 68.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 68 after subtracting 560 from 628.
Fetch the next digit (9) from the dividend, attach it to 68 and continue: 689 / 80

Going ahead to step 5:
80 goes into 689 8 times with a remainder of 49.
The next digit of our result is 8. 
Result so far: 178.0
Subtract 640 from 689 to get 49.
Fetch the next digit (3) from the dividend, attach it to 49 and continue: 493 / 80

Let's proceed to step 6:
The number 80 fits into 493 6 times, leaving a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 1786.0
If we subtract 480 from 493, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
The number 80 fits into 130 1 times, leaving a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 1786.1
Deduct 80 from 130 and we're left with 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 8:
The number 80 fits into 500 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 1786.16
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 9:
80 goes into 200 2 times with a remainder of 40.
The next digit of our result is 2. 
Result so far: 1786.162
Deduct 160 from 200 and we're left 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.

Advancing to step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1786.1625
Subtract 400 from 400 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 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1786.1625
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.

On to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1786.1625
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 1786.1625, and the remainder is 0.0.
