Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 808

Going ahead to step 3:
The number 808 fits into 589 0 times, leaving a remainder of 589.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 589, we end up with 589.
Grab the next digit (8) from the dividend, add it to 589, then carry on: 5898 / 808

Advancing to step 4:
If we divide 5898 by 808, we get 7 and a remainder of 242.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 5656 from 5898 and we're left with 242.
Fetch the next digit (1) from the dividend, attach it to 242 and continue: 2421 / 808

Let's proceed to step 5:
808 goes into 2421 2 times with a remainder of 805.
The next digit of our result is 2. 
Result so far: 72.0
Subtracting 1616 from 2421 leaves us with 805.
Fetch the next digit (6) from the dividend, attach it to 805 and continue: 8056 / 808

Moving on to step 6:
The number 808 fits into 8056 9 times, leaving a remainder of 784.
The number 9 becomes the next digit in our result. 
Result so far: 729.0
If we take 7272 away from 8056, we end up with 784.
Append the next digit (3) from the dividend to 784 and continue with: 7843 / 808

Advancing to step 7:
808 can be fit into 7843 9 times, resulting in a remainder of 571.
Record the quotient 9 as the next digit in the result. 
Result so far: 7299.0
Subtract 7272 from 7843 to get 571.
Take the next digit (4) from the dividend and append it to 571, then repeat: 5714 / 808

On to step 8:
808 can be fit into 5714 7 times, resulting in a remainder of 58.
The next digit of our result is 7. 
Result so far: 72997.0
The remainder is 58 after subtracting 5656 from 5714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
The number 808 fits into 580 0 times, leaving a remainder of 580.
Use 0 as the next digit of our solution. 
Result so far: 72997.0
Subtract 0 from 580 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 10:
If we divide 5800 by 808, we get 7 and a remainder of 144.
Use 7 as the next digit of our solution. 
Result so far: 72997.07
If we take 5656 away from 5800, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 11:
The number 808 fits into 1440 1 times, leaving a remainder of 632.
Write down 1 as next digit of the result. 
Result so far: 72997.071
Subtracting 808 from 1440 leaves us with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

On to step 12:
808 goes into 6320 7 times with a remainder of 664.
The next digit of our result is 7. 
Result so far: 72997.0717
If we subtract 5656 from 6320, we get 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

On to step 13:
The number 808 fits into 6640 8 times, leaving a remainder of 176.
Put 8 as the next digit of the answer. 
Result so far: 72997.07178
Subtract 6464 from 6640 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 14:
The number 808 fits into 1760 2 times, leaving a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 72997.071782
The remainder is 144 after subtracting 1616 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 15:
When dividing 1440 by 808, we get 1 with a remainder of 632.
Record the quotient 1 as the next digit in the result. 
Result so far: 72997.0717821
Subtracting 808 from 1440 leaves us with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

On to step 16:
6320 divided by 808 is 7 with a remainder of 664.
The number 7 becomes the next digit in our result. 
Result so far: 72997.07178217
The remainder is 664 after subtracting 5656 from 6320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

After the division, we end up with 72997.07178217 and a remainder of 6.64e-07.
