We divide 31581012 by 455
We want to divide 31581012 by 455.

Step 1:
When dividing 3 by 455, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 455

Advancing to step 2:
455 goes into 31 0 times with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 455

Step 3:
315 divided by 455 is 0 with a remainder of 315.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 315, we end up with 315.
Fetch the next digit (8) from the dividend, attach it to 315 and continue: 3158 / 455

Going ahead to step 4:
3158 divided by 455 is 6 with a remainder of 428.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 2730 from 3158 to get 428.
Append the next digit (1) from the dividend to 428 and continue with: 4281 / 455

Let's proceed to step 5:
455 can be fit into 4281 9 times, resulting in a remainder of 186.
Write down 9 as next digit of the result. 
Result so far: 69.0
Subtracting 4095 from 4281 leaves us with 186.
Fetch the next digit (0) from the dividend, attach it to 186 and continue: 1860 / 455

Advancing to step 6:
If we divide 1860 by 455, we get 4 and a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 694.0
If we subtract 1820 from 1860, we get 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 455

On to step 7:
455 can be fit into 401 0 times, resulting in a remainder of 401.
Record the quotient 0 as the next digit in the result. 
Result so far: 6940.0
If we take 0 away from 401, we end up with 401.
Bring next digit (2) of the dividend behind the 401 and repeat the process: 4012 / 455

Moving on to step 8:
4012 divided by 455 is 8 with a remainder of 372.
Write down 8 as next digit of the result. 
Result so far: 69408.0
Subtracting 3640 from 4012 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Let's proceed to step 9:
When dividing 3720 by 455, we get 8 with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 69408.8
The remainder is 80 after subtracting 3640 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
When dividing 800 by 455, we get 1 with a remainder of 345.
Write down 1 as next digit of the result. 
Result so far: 69408.81
Subtracting 455 from 800 leaves us with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 11:
If we divide 3450 by 455, we get 7 and a remainder of 265.
The number 7 becomes the next digit in our result. 
Result so far: 69408.817
If we subtract 3185 from 3450, we get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 12:
If we divide 2650 by 455, we get 5 and a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 69408.8175
Subtract 2275 from 2650 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 13:
The number 455 fits into 3750 8 times, leaving a remainder of 110.
Record the quotient 8 as the next digit in the result. 
Result so far: 69408.81758
If we take 3640 away from 3750, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 14:
455 goes into 1100 2 times with a remainder of 190.
Write down 2 as next digit of the result. 
Result so far: 69408.817582
The remainder is 190 after subtracting 910 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 15:
When dividing 1900 by 455, we get 4 with a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 69408.8175824
Subtract 1820 from 1900 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 16:
455 goes into 800 1 times with a remainder of 345.
Put 1 as the next digit of the answer. 
Result so far: 69408.81758241
The remainder is 345 after subtracting 455 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

The final outcome is 69408.81758241, with a leftover of 3.45e-07.
