Let's divide 166834 by 80
Let's see how many times 80 fits into 166834.

Going ahead 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
Subtracting 0 from 1 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 80

Step 2:
80 goes into 16 0 times with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 80

Moving on to step 3:
If we divide 166 by 80, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 160 from 166 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 80

Moving on to step 4:
80 goes into 68 0 times with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 68 after subtracting 0 from 68.
Bring next digit (3) of the dividend behind the 68 and repeat the process: 683 / 80

Moving on to step 5:
If we divide 683 by 80, we get 8 and a remainder of 43.
Write down 8 as next digit of the result. 
Result so far: 208.0
Deduct 640 from 683 and we're left with 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 80

Going ahead to step 6:
434 divided by 80 is 5 with a remainder of 34.
The next digit of our result is 5. 
Result so far: 2085.0
If we subtract 400 from 434, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 7:
The number 80 fits into 340 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 2085.4
If we take 320 away from 340, we end up 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 8:
If we divide 200 by 80, we get 2 and a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 2085.42
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.

On to step 9:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 2085.425
If we subtract 400 from 400, we 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.

Step 10:
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: 2085.425
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 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2085.425
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 2085.425 with a remaining 0.0.
