31822843 ÷ 812 
Our goal is to divide 31822843 by 812.

On to step 1:
The number 812 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 812

Step 2:
812 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
If we take 0 away from 31, we end up with 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 812

Moving on to step 3:
812 goes into 318 0 times with a remainder of 318.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 318 after subtracting 0 from 318.
Append the next digit (2) from the dividend to 318 and continue with: 3182 / 812

Going ahead to step 4:
812 can be fit into 3182 3 times, resulting in a remainder of 746.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2436 from 3182, we get 746.
Bring next digit (2) of the dividend behind the 746 and repeat the process: 7462 / 812

Let's proceed to step 5:
The number 812 fits into 7462 9 times, leaving a remainder of 154.
The next digit of our result is 9. 
Result so far: 39.0
If we subtract 7308 from 7462, we get 154.
Take the next digit (8) from the dividend and append it to 154, then repeat: 1548 / 812

Let's proceed to step 6:
The number 812 fits into 1548 1 times, leaving a remainder of 736.
Put 1 as the next digit of the answer. 
Result so far: 391.0
Subtracting 812 from 1548 leaves us with 736.
Bring next digit (4) of the dividend behind the 736 and repeat the process: 7364 / 812

Advancing to step 7:
812 can be fit into 7364 9 times, resulting in a remainder of 56.
Use 9 as the next digit of our solution. 
Result so far: 3919.0
Subtract 7308 from 7364 to get 56.
Append the next digit (3) from the dividend to 56 and continue with: 563 / 812

On to step 8:
563 divided by 812 is 0 with a remainder of 563.
The next digit of our result is 0. 
Result so far: 39190.0
Subtract 0 from 563 to get 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Let's proceed to step 9:
The number 812 fits into 5630 6 times, leaving a remainder of 758.
The next digit of our result is 6. 
Result so far: 39190.6
If we subtract 4872 from 5630, we get 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

Let's proceed to step 10:
7580 divided by 812 is 9 with a remainder of 272.
Record the quotient 9 as the next digit in the result. 
Result so far: 39190.69
The remainder is 272 after subtracting 7308 from 7580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 11:
The number 812 fits into 2720 3 times, leaving a remainder of 284.
Put 3 as the next digit of the answer. 
Result so far: 39190.693
Subtracting 2436 from 2720 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 12:
If we divide 2840 by 812, we get 3 and a remainder of 404.
The number 3 becomes the next digit in our result. 
Result so far: 39190.6933
The remainder is 404 after subtracting 2436 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

The final outcome is 39190.6933, with a leftover of 0.00404.
