Let's divide 830050 by 12
We want to divide 830050 by 12.

Going ahead to step 1:
12 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 12

On to step 2:
12 goes into 83 6 times with a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 72 away from 83, we end up with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 12

Advancing to step 3:
12 goes into 110 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
If we subtract 108 from 110, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 12

Step 4:
If we divide 20 by 12, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 691.0
If we take 12 away from 20, we end up with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 12

On to step 5:
If we divide 85 by 12, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 6917.0
If we subtract 84 from 85, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 12

Advancing to step 6:
When dividing 10 by 12, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 69170.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
12 goes into 100 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 69170.8
If we take 96 away from 100, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
If we divide 40 by 12, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 69170.83
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 69170.833
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 69170.833 with a remainder of 0.0004.
