518430 ÷ 81 
We're looking to find how many times 81 goes into 518430.

Advancing to step 1:
If we divide 5 by 81, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 81

Let's proceed 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
The remainder is 51 after subtracting 0 from 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 81

Advancing to step 3:
518 divided by 81 is 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 486 from 518 and we're left with 32.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 81

Let's proceed to step 4:
81 can be fit into 324 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 64.0
If we subtract 324 from 324, we get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 81

Advancing to step 5:
The number 81 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 640.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 81

Advancing to step 6:
When dividing 30 by 81, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 6400.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
81 goes into 300 3 times with a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 6400.3
Subtract 243 from 300 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 8:
When dividing 570 by 81, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 6400.37
If we take 567 away from 570, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
If we divide 30 by 81, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 6400.37
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
If we divide 300 by 81, we get 3 and a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 6400.3703
Subtracting 243 from 300 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 11:
If we divide 570 by 81, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 6400.37037
The remainder is 3 after subtracting 567 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
81 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 6400.37037
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
300 divided by 81 is 3 with a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 6400.3703703
If we subtract 243 from 300, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 14:
The number 81 fits into 570 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 6400.37037037
The remainder is 3 after subtracting 567 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 6400.37037037 with a balance of 3e-09.
