400216 ÷ 80 
We're looking to find how many times 80 goes into 400216.

Step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 80

Let's proceed to step 2:
80 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (0) from the dividend, attach it to 40 and continue: 400 / 80

On to step 3:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 400 from 400, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 80

Going ahead to step 4:
The number 80 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 80

Moving on to step 5:
When dividing 21 by 80, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 500.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 80

Moving on to step 6:
80 goes into 216 2 times with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 5002.0
The remainder is 56 after subtracting 160 from 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 7:
When dividing 560 by 80, we get 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 5002.7
Deduct 560 from 560 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.

Going ahead to step 8:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5002.7
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.

Going ahead to step 9:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5002.7
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.

After the division, we end up with 5002.7 and a remainder of 0.0.
