Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 736 and we're left with 736.
Fetch the next digit (8) from the dividend, attach it to 736 and continue: 7368 / 808

Going ahead to step 4:
808 goes into 7368 9 times with a remainder of 96.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 7272 away from 7368, we end up with 96.
Bring next digit (7) of the dividend behind the 96 and repeat the process: 967 / 808

Going ahead to step 5:
When dividing 967 by 808, we get 1 with a remainder of 159.
Put 1 as the next digit of the answer. 
Result so far: 91.0
If we subtract 808 from 967, we get 159.
Bring next digit (6) of the dividend behind the 159 and repeat the process: 1596 / 808

On to step 6:
When dividing 1596 by 808, we get 1 with a remainder of 788.
The number 1 becomes the next digit in our result. 
Result so far: 911.0
If we subtract 808 from 1596, we get 788.
Take the next digit (9) from the dividend and append it to 788, then repeat: 7889 / 808

On to step 7:
The number 808 fits into 7889 9 times, leaving a remainder of 617.
The number 9 becomes the next digit in our result. 
Result so far: 9119.0
If we take 7272 away from 7889, we end up with 617.
Fetch the next digit (0) from the dividend, attach it to 617 and continue: 6170 / 808

Step 8:
If we divide 6170 by 808, we get 7 and a remainder of 514.
Write down 7 as next digit of the result. 
Result so far: 91197.0
Deduct 5656 from 6170 and we're left with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Let's proceed to step 9:
808 can be fit into 5140 6 times, resulting in a remainder of 292.
Record the quotient 6 as the next digit in the result. 
Result so far: 91197.6
Deduct 4848 from 5140 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 10:
808 goes into 2920 3 times with a remainder of 496.
The next digit of our result is 3. 
Result so far: 91197.63
If we subtract 2424 from 2920, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 11:
808 can be fit into 4960 6 times, resulting in a remainder of 112.
Put 6 as the next digit of the answer. 
Result so far: 91197.636
If we subtract 4848 from 4960, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 12:
808 goes into 1120 1 times with a remainder of 312.
The number 1 becomes the next digit in our result. 
Result so far: 91197.6361
Deduct 808 from 1120 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 13:
The number 808 fits into 3120 3 times, leaving a remainder of 696.
Write down 3 as next digit of the result. 
Result so far: 91197.63613
Deduct 2424 from 3120 and we're left with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Step 14:
When dividing 6960 by 808, we get 8 with a remainder of 496.
Record the quotient 8 as the next digit in the result. 
Result so far: 91197.636138
The remainder is 496 after subtracting 6464 from 6960.
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 15:
808 can be fit into 4960 6 times, resulting in a remainder of 112.
Put 6 as the next digit of the answer. 
Result so far: 91197.6361386
If we take 4848 away from 4960, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 16:
1120 divided by 808 is 1 with a remainder of 312.
Record the quotient 1 as the next digit in the result. 
Result so far: 91197.63613861
If we take 808 away from 1120, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

In conclusion, the division gives 91197.63613861 with a balance of 3.12e-07.
