402613 ÷ 80 
Let's see how many times 80 fits into 402613.

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
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 80

Moving on to step 2:
The number 80 fits into 40 0 times, leaving 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.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 80

Step 3:
80 goes into 402 5 times with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 400 away from 402, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 80

Advancing to step 4:
If we divide 26 by 80, we get 0 and a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 50.0
Subtracting 0 from 26 leaves us with 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 80

Advancing to step 5:
The number 80 fits into 261 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 503.0
The remainder is 21 after subtracting 240 from 261.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 80

On to step 6:
80 can be fit into 213 2 times, resulting in a remainder of 53.
Use 2 as the next digit of our solution. 
Result so far: 5032.0
The remainder is 53 after subtracting 160 from 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
530 divided by 80 is 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 5032.6
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.

Going ahead to step 8:
500 divided by 80 is 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 5032.66
If we take 480 away from 500, 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.

The quotient of the division is 5032.66, and the remainder is 0.02.
