We divide 516745 by 81
We're looking to find how many times 81 goes into 516745.

On to step 1:
5 divided by 81 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 81

On to step 2:
51 divided by 81 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 81

Advancing to step 3:
The number 81 fits into 516 6 times, leaving a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 486 from 516 to get 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 81

Step 4:
307 divided by 81 is 3 with a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
The remainder is 64 after subtracting 243 from 307.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 81

Moving on to step 5:
644 divided by 81 is 7 with a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 637.0
Deduct 567 from 644 and we're left with 77.
Grab the next digit (5) from the dividend, add it to 77, then carry on: 775 / 81

Step 6:
775 divided by 81 is 9 with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 6379.0
If we take 729 away from 775, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 7:
81 can be fit into 460 5 times, resulting in a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 6379.5
If we take 405 away from 460, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 8:
81 goes into 550 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 6379.56
Deduct 486 from 550 and we're left 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.

Going ahead to step 9:
If we divide 640 by 81, we get 7 and a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 6379.567
Deduct 567 from 640 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 10:
730 divided by 81 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 6379.5679
Subtracting 729 from 730 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
If we divide 10 by 81, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 6379.5679
Subtracting 0 from 10 leaves us 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 12:
81 goes into 100 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 6379.567901
If we subtract 81 from 100, we get 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 13:
When dividing 190 by 81, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 6379.5679012
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.

Going ahead to step 14:
When dividing 280 by 81, we get 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 6379.56790123
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.

The final outcome is 6379.56790123, with a leftover of 3.7e-08.
