30850864 divided by 809 
We want to figure out the number of times 30850864 can be divided by 809.

Going ahead to step 1:
809 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 809

On to step 2:
When dividing 30 by 809, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 809

Moving on to step 3:
If we divide 308 by 809, we get 0 and a remainder of 308.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 308 leaves us with 308.
Include the next digit (5) from the dividend after 308, then repeat: 3085 / 809

Let's proceed to step 4:
809 goes into 3085 3 times with a remainder of 658.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 2427 from 3085 leaves us with 658.
Bring next digit (0) of the dividend behind the 658 and repeat the process: 6580 / 809

Going ahead to step 5:
When dividing 6580 by 809, we get 8 with a remainder of 108.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Deduct 6472 from 6580 and we're left with 108.
Take the next digit (8) from the dividend and append it to 108, then repeat: 1088 / 809

Moving on to step 6:
809 goes into 1088 1 times with a remainder of 279.
Use 1 as the next digit of our solution. 
Result so far: 381.0
If we subtract 809 from 1088, we get 279.
Grab the next digit (6) from the dividend, add it to 279, then carry on: 2796 / 809

Moving on to step 7:
2796 divided by 809 is 3 with a remainder of 369.
Record the quotient 3 as the next digit in the result. 
Result so far: 3813.0
Subtract 2427 from 2796 to get 369.
Grab the next digit (4) from the dividend, add it to 369, then carry on: 3694 / 809

On to step 8:
3694 divided by 809 is 4 with a remainder of 458.
Write down 4 as next digit of the result. 
Result so far: 38134.0
Subtract 3236 from 3694 to get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Let's proceed to step 9:
When dividing 4580 by 809, we get 5 with a remainder of 535.
Put 5 as the next digit of the answer. 
Result so far: 38134.5
Subtracting 4045 from 4580 leaves us with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

On to step 10:
If we divide 5350 by 809, we get 6 and a remainder of 496.
The next digit of our result is 6. 
Result so far: 38134.56
If we take 4854 away from 5350, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Let's proceed to step 11:
809 goes into 4960 6 times with a remainder of 106.
The next digit of our result is 6. 
Result so far: 38134.566
If we subtract 4854 from 4960, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

The quotient of the division is 38134.566, and the remainder is 0.0106.
