401173 divided by 80 
We want to figure out the number of times 401173 can be divided by 80.

Advancing to step 1:
If we divide 4 by 80, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 80

Going ahead to step 2:
40 divided by 80 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 80

Going ahead to step 3:
80 can be fit into 401 5 times, resulting in a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 1 after subtracting 400 from 401.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 80

Step 4:
When dividing 11 by 80, we get 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Deduct 0 from 11 and we're left with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 80

Let's proceed to step 5:
The number 80 fits into 117 1 times, leaving a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 501.0
Subtract 80 from 117 to get 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 80

Advancing to step 6:
373 divided by 80 is 4 with a remainder of 53.
The number 4 becomes the next digit in our result. 
Result so far: 5014.0
If we subtract 320 from 373, we get 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:
When dividing 530 by 80, we get 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 5014.6
If we take 480 away from 530, we end up 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.

Going ahead to step 8:
If we divide 500 by 80, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 5014.66
Subtract 480 from 500 to 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.

The quotient of the division is 5014.66, and the remainder is 0.02.
