Let's divide 405071 by 80
We want to divide 405071 by 80.

Going ahead to step 1:
80 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 80

Advancing to step 2:
If we divide 40 by 80, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 80

Advancing to step 3:
The number 80 fits into 405 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 400 from 405 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 80

Advancing to step 4:
When dividing 50 by 80, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
If we subtract 0 from 50, we get 50.
Fetch the next digit (7) from the dividend, attach it to 50 and continue: 507 / 80

Advancing to step 5:
80 can be fit into 507 6 times, resulting in a remainder of 27.
The next digit of our result is 6. 
Result so far: 506.0
Subtract 480 from 507 to get 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 80

Going ahead to step 6:
271 divided by 80 is 3 with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 5063.0
Deduct 240 from 271 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
If we divide 310 by 80, we get 3 and a remainder of 70.
The next digit of our result is 3. 
Result so far: 5063.3
Deduct 240 from 310 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
When dividing 700 by 80, we get 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 5063.38
If we take 640 away from 700, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
80 goes into 600 7 times with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 5063.387
If we subtract 560 from 600, we 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.

On to step 10:
80 goes into 400 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5063.3875
Deduct 400 from 400 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.

Moving on to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5063.3875
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5063.3875
If we subtract 0 from 0, we get 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 quotient of the division is 5063.3875, and the remainder is 0.0.
