30640634 divided by 831 
We want to figure out the number of times 30640634 can be divided by 831.

Let's proceed to step 1:
If we divide 3 by 831, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 831

On to step 2:
When dividing 30 by 831, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 831

Going ahead to step 3:
If we divide 306 by 831, we get 0 and a remainder of 306.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 306, we get 306.
Include the next digit (4) from the dividend after 306, then repeat: 3064 / 831

Step 4:
831 goes into 3064 3 times with a remainder of 571.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2493 from 3064 and we're left with 571.
Take the next digit (0) from the dividend and append it to 571, then repeat: 5710 / 831

Let's proceed to step 5:
5710 divided by 831 is 6 with a remainder of 724.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we subtract 4986 from 5710, we get 724.
Bring next digit (6) of the dividend behind the 724 and repeat the process: 7246 / 831

Advancing to step 6:
If we divide 7246 by 831, we get 8 and a remainder of 598.
The next digit of our result is 8. 
Result so far: 368.0
Deduct 6648 from 7246 and we're left with 598.
Include the next digit (3) from the dividend after 598, then repeat: 5983 / 831

Advancing to step 7:
831 can be fit into 5983 7 times, resulting in a remainder of 166.
Write down 7 as next digit of the result. 
Result so far: 3687.0
If we subtract 5817 from 5983, we get 166.
Include the next digit (4) from the dividend after 166, then repeat: 1664 / 831

Advancing to step 8:
1664 divided by 831 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 36872.0
The remainder is 2 after subtracting 1662 from 1664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
If we divide 20 by 831, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 36872.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
If we divide 200 by 831, we get 0 and a remainder of 200.
The next digit of our result is 0. 
Result so far: 36872.0
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 36872.0 and a remainder of 0.2.
