58518 ÷ 81 
We want to figure out the number of times 58518 can be divided by 81.

Advancing to 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.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 81

Advancing to step 2:
81 goes into 58 0 times with a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Bring next digit (5) of the dividend behind the 58 and repeat the process: 585 / 81

Let's proceed to step 3:
81 can be fit into 585 7 times, resulting in a remainder of 18.
The next digit of our result is 7. 
Result so far: 7.0
If we take 567 away from 585, we end up with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 81

Let's proceed to step 4:
81 goes into 181 2 times with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 72.0
The remainder is 19 after subtracting 162 from 181.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 81

Advancing to step 5:
The number 81 fits into 198 2 times, leaving a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 722.0
Subtract 162 from 198 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 6:
The number 81 fits into 360 4 times, leaving a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 722.4
If we subtract 324 from 360, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
81 goes into 360 4 times with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 722.44
The remainder is 36 after subtracting 324 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 722.44 with a remaining 0.036.
