We're dividing 596515 by 81 
We want to figure out the number of times 596515 can be divided by 81.

Step 1:
The number 81 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 81

Moving on to step 2:
When dividing 59 by 81, we get 0 with a remainder of 59.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 59, we get 59.
Bring next digit (6) of the dividend behind the 59 and repeat the process: 596 / 81

On to step 3:
The number 81 fits into 596 7 times, leaving a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 567 from 596, we get 29.
Bring next digit (5) of the dividend behind the 29 and repeat the process: 295 / 81

Step 4:
When dividing 295 by 81, we get 3 with a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
If we subtract 243 from 295, we get 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 81

On to step 5:
81 can be fit into 521 6 times, resulting in a remainder of 35.
The number 6 becomes the next digit in our result. 
Result so far: 736.0
If we subtract 486 from 521, we get 35.
Append the next digit (5) from the dividend to 35 and continue with: 355 / 81

On to step 6:
355 divided by 81 is 4 with a remainder of 31.
Record the quotient 4 as the next digit in the result. 
Result so far: 7364.0
Subtracting 324 from 355 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
When dividing 310 by 81, we get 3 with a remainder of 67.
The next digit of our result is 3. 
Result so far: 7364.3
Deduct 243 from 310 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 8:
If we divide 670 by 81, we get 8 and a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 7364.38
If we subtract 648 from 670, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
81 can be fit into 220 2 times, resulting in a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 7364.382
If we take 162 away from 220, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
The number 81 fits into 580 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 7364.3827
Subtract 567 from 580 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 11:
If we divide 130 by 81, we get 1 and a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 7364.38271
Subtracting 81 from 130 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 12:
81 can be fit into 490 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 7364.382716
Subtract 486 from 490 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.

Let's proceed to step 13:
81 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 7364.382716
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
400 divided by 81 is 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 7364.38271604
If we take 324 away from 400, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 7364.38271604 with a remainder of 7.6e-08.
