402340 divided by 80 
We're looking to find how many times 80 goes into 402340.

Advancing to step 1:
When dividing 4 by 80, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 80

Step 2:
80 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 80

Step 3:
402 divided by 80 is 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 2 after subtracting 400 from 402.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 80

On to step 4:
80 can be fit into 23 0 times, resulting in a remainder of 23.
The next digit of our result is 0. 
Result so far: 50.0
If we take 0 away from 23, we end up with 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 80

Moving on to step 5:
80 can be fit into 234 2 times, resulting in a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 502.0
Deduct 160 from 234 and we're left with 74.
Grab the next digit (0) from the dividend, add it to 74, then carry on: 740 / 80

Going ahead to step 6:
740 divided by 80 is 9 with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 5029.0
Deduct 720 from 740 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.

Moving on to step 7:
If we divide 200 by 80, we get 2 and a remainder of 40.
The next digit of our result is 2. 
Result so far: 5029.2
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.

Let's proceed to step 8:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5029.25
The remainder is 0 after subtracting 400 from 400.
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 9:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5029.25
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.

Let's proceed to step 10:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5029.25
Deduct 0 from 0 and we're left 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.

The final result is 5029.25 with a remainder of 0.0.
