We're dividing 393209 by 813 
We want to figure out the number of times 393209 can be divided by 813.

Advancing to step 1:
813 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 813

Let's proceed to step 2:
39 divided by 813 is 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 813

On to step 3:
813 can be fit into 393 0 times, resulting in a remainder of 393.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 393 after subtracting 0 from 393.
Fetch the next digit (2) from the dividend, attach it to 393 and continue: 3932 / 813

Moving on to step 4:
If we divide 3932 by 813, we get 4 and a remainder of 680.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 680 after subtracting 3252 from 3932.
Append the next digit (0) from the dividend to 680 and continue with: 6800 / 813

Advancing to step 5:
When dividing 6800 by 813, we get 8 with a remainder of 296.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we subtract 6504 from 6800, we get 296.
Append the next digit (9) from the dividend to 296 and continue with: 2969 / 813

On to step 6:
813 goes into 2969 3 times with a remainder of 530.
The next digit of our result is 3. 
Result so far: 483.0
The remainder is 530 after subtracting 2439 from 2969.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 7:
When dividing 5300 by 813, we get 6 with a remainder of 422.
Record the quotient 6 as the next digit in the result. 
Result so far: 483.6
Deduct 4878 from 5300 and we're left with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Going ahead to step 8:
When dividing 4220 by 813, we get 5 with a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 483.65
If we take 4065 away from 4220, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 9:
The number 813 fits into 1550 1 times, leaving a remainder of 737.
Put 1 as the next digit of the answer. 
Result so far: 483.651
If we take 813 away from 1550, we end up with 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

Going ahead to step 10:
7370 divided by 813 is 9 with a remainder of 53.
Use 9 as the next digit of our solution. 
Result so far: 483.6519
If we take 7317 away from 7370, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 11:
813 goes into 530 0 times with a remainder of 530.
Write down 0 as next digit of the result. 
Result so far: 483.6519
Subtracting 0 from 530 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Moving on to step 12:
When dividing 5300 by 813, we get 6 with a remainder of 422.
Use 6 as the next digit of our solution. 
Result so far: 483.651906
If we take 4878 away from 5300, we end up with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Step 13:
When dividing 4220 by 813, we get 5 with a remainder of 155.
Record the quotient 5 as the next digit in the result. 
Result so far: 483.6519065
If we subtract 4065 from 4220, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 14:
If we divide 1550 by 813, we get 1 and a remainder of 737.
Use 1 as the next digit of our solution. 
Result so far: 483.65190651
Subtracting 813 from 1550 leaves us with 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

After the division, we end up with 483.65190651 and a remainder of 7.37e-07.
