401086 ÷ 80 
We want to figure out the number of times 401086 can be divided by 80.

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.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 80

Advancing to step 2:
80 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 80

Step 3:
The number 80 fits into 401 5 times, leaving a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 400 from 401 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 80

Going ahead to step 4:
80 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
If we subtract 0 from 10, we get 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 80

Let's proceed to step 5:
80 goes into 108 1 times with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 501.0
Deduct 80 from 108 and we're left with 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 80

Moving on to step 6:
286 divided by 80 is 3 with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 5013.0
Subtract 240 from 286 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
When dividing 460 by 80, we get 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 5013.5
If we subtract 400 from 460, we 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.

Step 8:
When dividing 600 by 80, we get 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 5013.57
Subtracting 560 from 600 leaves us 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.

Let's proceed to step 9:
400 divided by 80 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5013.575
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 10:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5013.575
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 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5013.575
Subtracting 0 from 0 leaves us 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.

Our division results in 5013.575 with a remaining 0.0.
