290133 ÷ 80 
We want to divide 290133 by 80.

Step 1:
The number 80 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 80

Step 2:
The number 80 fits into 29 0 times, leaving a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 80

Moving on to step 3:
80 can be fit into 290 3 times, resulting in a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 240 from 290, we get 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 80

Let's proceed to step 4:
If we divide 501 by 80, we get 6 and a remainder of 21.
The next digit of our result is 6. 
Result so far: 36.0
If we take 480 away from 501, we end up with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 80

Let's proceed to step 5:
The number 80 fits into 213 2 times, leaving a remainder of 53.
Record the quotient 2 as the next digit in the result. 
Result so far: 362.0
Subtracting 160 from 213 leaves us with 53.
Bring next digit (3) of the dividend behind the 53 and repeat the process: 533 / 80

Step 6:
The number 80 fits into 533 6 times, leaving a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 3626.0
If we take 480 away from 533, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
80 can be fit into 530 6 times, resulting in a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 3626.6
Subtracting 480 from 530 leaves us 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.

Moving on to step 8:
If we divide 500 by 80, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 3626.66
Deduct 480 from 500 and we're left 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.

Our division results in 3626.66 with a remaining 0.02.
