We're dividing 403342 by 80 
We want to figure out the number of times 403342 can be divided by 80.

Advancing to step 1:
When dividing 4 by 80, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 80

Step 2:
When dividing 40 by 80, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 80

Moving on to step 3:
80 can be fit into 403 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 400 from 403 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 80

On to step 4:
33 divided by 80 is 0 with a remainder of 33.
The next digit of our result is 0. 
Result so far: 50.0
The remainder is 33 after subtracting 0 from 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 80

Moving on to step 5:
80 can be fit into 334 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 504.0
The remainder is 14 after subtracting 320 from 334.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 80

Step 6:
When dividing 142 by 80, we get 1 with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 5041.0
The remainder is 62 after subtracting 80 from 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 7:
80 goes into 620 7 times with a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 5041.7
Subtract 560 from 620 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 5041.77
Deduct 560 from 600 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.

The final result is 5041.77 with a remainder of 0.04.
