We look at the division of 166977 by 80 
We want to divide 166977 by 80.

On to step 1:
1 divided by 80 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 80

On to step 2:
If we divide 16 by 80, we get 0 and a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 80

On to step 3:
166 divided by 80 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 160 away from 166, we end up with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 80

Moving on to step 4:
80 goes into 69 0 times with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 69, we get 69.
Take the next digit (7) from the dividend and append it to 69, then repeat: 697 / 80

Step 5:
The number 80 fits into 697 8 times, leaving a remainder of 57.
Record the quotient 8 as the next digit in the result. 
Result so far: 208.0
Subtract 640 from 697 to get 57.
Include the next digit (7) from the dividend after 57, then repeat: 577 / 80

Let's proceed to step 6:
80 can be fit into 577 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 2087.0
If we take 560 away from 577, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
170 divided by 80 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2087.2
Subtract 160 from 170 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
80 can be fit into 100 1 times, resulting in a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 2087.21
If we subtract 80 from 100, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 2087.212
Subtract 160 from 200 to 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.

Going ahead to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2087.2125
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.

Moving on to step 11:
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: 2087.2125
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.

Moving on 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: 2087.2125
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.

Our division results in 2087.2125 with a remaining 0.0.
