500811 ÷ 31 
We're looking to find how many times 31 goes into 500811.

Advancing to step 1:
31 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 31

Moving on to step 2:
The number 31 fits into 50 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 31 from 50 and we're left with 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 31

Going ahead to step 3:
When dividing 190 by 31, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 186 from 190 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 31

Advancing to step 4:
31 can be fit into 48 1 times, resulting in a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 161.0
If we take 31 away from 48, we end up with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 31

Step 5:
171 divided by 31 is 5 with a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 1615.0
Deduct 155 from 171 and we're left with 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 31

Advancing to step 6:
If we divide 161 by 31, we get 5 and a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 16155.0
Subtract 155 from 161 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
If we divide 60 by 31, we get 1 and a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 16155.1
Subtracting 31 from 60 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 8:
31 can be fit into 290 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 16155.19
If we subtract 279 from 290, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
If we divide 110 by 31, we get 3 and a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 16155.193
If we take 93 away from 110, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 10:
31 goes into 170 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 16155.1935
If we take 155 away from 170, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
When dividing 150 by 31, we get 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 16155.19354
The remainder is 26 after subtracting 124 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
31 goes into 260 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 16155.193548
Subtracting 248 from 260 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
If we divide 120 by 31, we get 3 and a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 16155.1935483
The remainder is 27 after subtracting 93 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 14:
31 can be fit into 270 8 times, resulting in a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 16155.19354838
Subtracting 248 from 270 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 16155.19354838, with a leftover of 2.2e-08.
