537166 ÷ 81 
Our goal is to divide 537166 by 81.

Let's proceed to step 1:
81 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 81

On to step 2:
53 divided by 81 is 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 81

Step 3:
When dividing 537 by 81, we get 6 with a remainder of 51.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 486 from 537 to get 51.
Take the next digit (1) from the dividend and append it to 51, then repeat: 511 / 81

On to step 4:
When dividing 511 by 81, we get 6 with a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtract 486 from 511 to get 25.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 81

Moving on to step 5:
256 divided by 81 is 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 663.0
If we take 243 away from 256, we end up with 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 81

Let's proceed to step 6:
81 goes into 136 1 times with a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 6631.0
Subtract 81 from 136 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 7:
When dividing 550 by 81, we get 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 6631.6
If we take 486 away from 550, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 8:
If we divide 640 by 81, we get 7 and a remainder of 73.
The next digit of our result is 7. 
Result so far: 6631.67
If we subtract 567 from 640, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 9:
When dividing 730 by 81, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 6631.679
Subtract 729 from 730 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
When dividing 10 by 81, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 6631.679
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
81 goes into 100 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 6631.67901
Subtracting 81 from 100 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
81 goes into 190 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 6631.679012
If we take 162 away from 190, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
When dividing 280 by 81, we get 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 6631.6790123
The remainder is 37 after subtracting 243 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 14:
81 goes into 370 4 times with a remainder of 46.
The next digit of our result is 4. 
Result so far: 6631.67901234
If we subtract 324 from 370, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The quotient of the division is 6631.67901234, and the remainder is 4.6e-08.
