We're dividing 537393 by 81 
We want to figure out the number of times 537393 can be divided by 81.

Step 1:
81 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 81

Let's proceed to step 2:
If we divide 53 by 81, we get 0 and a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Bring next digit (7) of the dividend behind the 53 and repeat the process: 537 / 81

Going ahead to step 3:
If we divide 537 by 81, we get 6 and a remainder of 51.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 486 from 537, we get 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 81

On to step 4:
If we divide 513 by 81, we get 6 and a remainder of 27.
Put 6 as the next digit of the answer. 
Result so far: 66.0
If we take 486 away from 513, we end up with 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 81

Step 5:
81 can be fit into 279 3 times, resulting in a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 663.0
Subtracting 243 from 279 leaves us with 36.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 81

Moving on to step 6:
When dividing 363 by 81, we get 4 with a remainder of 39.
Write down 4 as next digit of the result. 
Result so far: 6634.0
Subtract 324 from 363 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
81 goes into 390 4 times with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 6634.4
The remainder is 66 after subtracting 324 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
81 can be fit into 660 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 6634.48
Deduct 648 from 660 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
120 divided by 81 is 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 6634.481
If we take 81 away from 120, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 10:
81 can be fit into 390 4 times, resulting in a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 6634.4814
Deduct 324 from 390 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 11:
When dividing 660 by 81, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 6634.48148
Subtracting 648 from 660 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
When dividing 120 by 81, we get 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 6634.481481
If we subtract 81 from 120, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 13:
When dividing 390 by 81, we get 4 with a remainder of 66.
The next digit of our result is 4. 
Result so far: 6634.4814814
If we take 324 away from 390, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 14:
When dividing 660 by 81, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 6634.48148148
If we subtract 648 from 660, 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 quotient of the division is 6634.48148148, and the remainder is 1.2e-08.
