Deduct 0 from 7 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 836

Advancing to step 2:
When dividing 73 by 836, we get 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Include the next digit (0) from the dividend after 73, then repeat: 730 / 836

Advancing to step 3:
836 goes into 730 0 times with a remainder of 730.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 730 to get 730.
Bring next digit (6) of the dividend behind the 730 and repeat the process: 7306 / 836

On to step 4:
836 goes into 7306 8 times with a remainder of 618.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 6688 from 7306 and we're left with 618.
Fetch the next digit (8) from the dividend, attach it to 618 and continue: 6188 / 836

On to step 5:
836 can be fit into 6188 7 times, resulting in a remainder of 336.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Subtract 5852 from 6188 to get 336.
Take the next digit (9) from the dividend and append it to 336, then repeat: 3369 / 836

Going ahead to step 6:
When dividing 3369 by 836, we get 4 with a remainder of 25.
The next digit of our result is 4. 
Result so far: 874.0
The remainder is 25 after subtracting 3344 from 3369.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 836

Moving on to step 7:
When dividing 259 by 836, we get 0 with a remainder of 259.
Record the quotient 0 as the next digit in the result. 
Result so far: 8740.0
Subtracting 0 from 259 leaves us with 259.
Grab the next digit (7) from the dividend, add it to 259, then carry on: 2597 / 836

Let's proceed to step 8:
836 can be fit into 2597 3 times, resulting in a remainder of 89.
Write down 3 as next digit of the result. 
Result so far: 87403.0
Subtracting 2508 from 2597 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 9:
When dividing 890 by 836, we get 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 87403.1
The remainder is 54 after subtracting 836 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
When dividing 540 by 836, we get 0 with a remainder of 540.
Write down 0 as next digit of the result. 
Result so far: 87403.1
The remainder is 540 after subtracting 0 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 11:
When dividing 5400 by 836, we get 6 with a remainder of 384.
The number 6 becomes the next digit in our result. 
Result so far: 87403.106
The remainder is 384 after subtracting 5016 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 12:
When dividing 3840 by 836, we get 4 with a remainder of 496.
Record the quotient 4 as the next digit in the result. 
Result so far: 87403.1064
Subtracting 3344 from 3840 leaves us 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.

Going ahead to step 13:
When dividing 4960 by 836, we get 5 with a remainder of 780.
Write down 5 as next digit of the result. 
Result so far: 87403.10645
If we take 4180 away from 4960, we end up with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Step 14:
7800 divided by 836 is 9 with a remainder of 276.
The number 9 becomes the next digit in our result. 
Result so far: 87403.106459
Subtracting 7524 from 7800 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 15:
When dividing 2760 by 836, we get 3 with a remainder of 252.
The next digit of our result is 3. 
Result so far: 87403.1064593
If we subtract 2508 from 2760, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 16:
The number 836 fits into 2520 3 times, leaving a remainder of 12.
The next digit of our result is 3. 
Result so far: 87403.10645933
If we subtract 2508 from 2520, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 87403.10645933 with a remainder of 1.2e-08.
