31034443 divided by 820 
Let's see how many times 820 fits into 31034443.

Advancing to step 1:
If we divide 3 by 820, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 820

Moving on to step 2:
If we divide 31 by 820, we get 0 and 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.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 820

Going ahead to step 3:
The number 820 fits into 310 0 times, leaving a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 310 to get 310.
Include the next digit (3) from the dividend after 310, then repeat: 3103 / 820

Advancing to step 4:
The number 820 fits into 3103 3 times, leaving a remainder of 643.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 2460 away from 3103, we end up with 643.
Grab the next digit (4) from the dividend, add it to 643, then carry on: 6434 / 820

Moving on to step 5:
The number 820 fits into 6434 7 times, leaving a remainder of 694.
Write down 7 as next digit of the result. 
Result so far: 37.0
The remainder is 694 after subtracting 5740 from 6434.
Fetch the next digit (4) from the dividend, attach it to 694 and continue: 6944 / 820

On to step 6:
6944 divided by 820 is 8 with a remainder of 384.
The number 8 becomes the next digit in our result. 
Result so far: 378.0
The remainder is 384 after subtracting 6560 from 6944.
Take the next digit (4) from the dividend and append it to 384, then repeat: 3844 / 820

Moving on to step 7:
820 can be fit into 3844 4 times, resulting in a remainder of 564.
Use 4 as the next digit of our solution. 
Result so far: 3784.0
If we subtract 3280 from 3844, we get 564.
Grab the next digit (3) from the dividend, add it to 564, then carry on: 5643 / 820

Moving on to step 8:
When dividing 5643 by 820, we get 6 with a remainder of 723.
Put 6 as the next digit of the answer. 
Result so far: 37846.0
Deduct 4920 from 5643 and we're left with 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Step 9:
820 goes into 7230 8 times with a remainder of 670.
The next digit of our result is 8. 
Result so far: 37846.8
The remainder is 670 after subtracting 6560 from 7230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Advancing to step 10:
When dividing 6700 by 820, we get 8 with a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 37846.88
If we take 6560 away from 6700, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The quotient of the division is 37846.88, and the remainder is 0.14.
