31310511 ÷ 485 
Let's see how many times 485 fits into 31310511.

Let's proceed to step 1:
485 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 485

Let's proceed to step 2:
485 goes into 31 0 times with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 485

Step 3:
The number 485 fits into 313 0 times, leaving a remainder of 313.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 313, we get 313.
Bring next digit (1) of the dividend behind the 313 and repeat the process: 3131 / 485

Going ahead to step 4:
The number 485 fits into 3131 6 times, leaving a remainder of 221.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 221 after subtracting 2910 from 3131.
Grab the next digit (0) from the dividend, add it to 221, then carry on: 2210 / 485

Let's proceed to step 5:
2210 divided by 485 is 4 with a remainder of 270.
The next digit of our result is 4. 
Result so far: 64.0
If we take 1940 away from 2210, we end up with 270.
Grab the next digit (5) from the dividend, add it to 270, then carry on: 2705 / 485

On to step 6:
2705 divided by 485 is 5 with a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 645.0
Deduct 2425 from 2705 and we're left with 280.
Grab the next digit (1) from the dividend, add it to 280, then carry on: 2801 / 485

Step 7:
2801 divided by 485 is 5 with a remainder of 376.
Use 5 as the next digit of our solution. 
Result so far: 6455.0
Subtract 2425 from 2801 to get 376.
Include the next digit (1) from the dividend after 376, then repeat: 3761 / 485

Let's proceed to step 8:
3761 divided by 485 is 7 with a remainder of 366.
Write down 7 as next digit of the result. 
Result so far: 64557.0
Subtract 3395 from 3761 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 9:
The number 485 fits into 3660 7 times, leaving a remainder of 265.
Put 7 as the next digit of the answer. 
Result so far: 64557.7
Subtracting 3395 from 3660 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 10:
2650 divided by 485 is 5 with a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 64557.75
Subtracting 2425 from 2650 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 11:
The number 485 fits into 2250 4 times, leaving a remainder of 310.
The next digit of our result is 4. 
Result so far: 64557.754
Subtract 1940 from 2250 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 12:
485 goes into 3100 6 times with a remainder of 190.
The number 6 becomes the next digit in our result. 
Result so far: 64557.7546
Subtract 2910 from 3100 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 13:
If we divide 1900 by 485, we get 3 and a remainder of 445.
Put 3 as the next digit of the answer. 
Result so far: 64557.75463
If we take 1455 away from 1900, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 14:
4450 divided by 485 is 9 with a remainder of 85.
Put 9 as the next digit of the answer. 
Result so far: 64557.754639
If we subtract 4365 from 4450, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 15:
485 can be fit into 850 1 times, resulting in a remainder of 365.
Put 1 as the next digit of the answer. 
Result so far: 64557.7546391
The remainder is 365 after subtracting 485 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Moving on to step 16:
When dividing 3650 by 485, we get 7 with a remainder of 255.
Write down 7 as next digit of the result. 
Result so far: 64557.75463917
If we take 3395 away from 3650, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

After the division, we end up with 64557.75463917 and a remainder of 2.55e-07.
