31210710 divided by 814 
We want to divide 31210710 by 814.

On to step 1:
814 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 814

Let's proceed to step 2:
814 can be fit into 31 0 times, resulting in a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 814

Advancing to step 3:
When dividing 312 by 814, we get 0 with a remainder of 312.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 312 to get 312.
Grab the next digit (1) from the dividend, add it to 312, then carry on: 3121 / 814

On to step 4:
814 can be fit into 3121 3 times, resulting in a remainder of 679.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 2442 away from 3121, we end up with 679.
Bring next digit (0) of the dividend behind the 679 and repeat the process: 6790 / 814

On to step 5:
When dividing 6790 by 814, we get 8 with a remainder of 278.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Subtracting 6512 from 6790 leaves us with 278.
Fetch the next digit (7) from the dividend, attach it to 278 and continue: 2787 / 814

On to step 6:
814 goes into 2787 3 times with a remainder of 345.
The next digit of our result is 3. 
Result so far: 383.0
If we take 2442 away from 2787, we end up with 345.
Bring next digit (1) of the dividend behind the 345 and repeat the process: 3451 / 814

Let's proceed to step 7:
814 goes into 3451 4 times with a remainder of 195.
Use 4 as the next digit of our solution. 
Result so far: 3834.0
Subtract 3256 from 3451 to get 195.
Take the next digit (0) from the dividend and append it to 195, then repeat: 1950 / 814

Advancing to step 8:
814 can be fit into 1950 2 times, resulting in a remainder of 322.
Use 2 as the next digit of our solution. 
Result so far: 38342.0
Subtract 1628 from 1950 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 9:
3220 divided by 814 is 3 with a remainder of 778.
Write down 3 as next digit of the result. 
Result so far: 38342.3
The remainder is 778 after subtracting 2442 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Going ahead to step 10:
The number 814 fits into 7780 9 times, leaving a remainder of 454.
Record the quotient 9 as the next digit in the result. 
Result so far: 38342.39
If we subtract 7326 from 7780, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Moving on to step 11:
When dividing 4540 by 814, we get 5 with a remainder of 470.
Put 5 as the next digit of the answer. 
Result so far: 38342.395
If we take 4070 away from 4540, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 12:
If we divide 4700 by 814, we get 5 and a remainder of 630.
Write down 5 as next digit of the result. 
Result so far: 38342.3955
Subtracting 4070 from 4700 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

The final result is 38342.3955 with a remainder of 0.0063.
