We're dividing 118458 by 81 
We want to figure out the number of times 118458 can be divided by 81.

On to step 1:
81 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 81

Moving on to step 2:
The number 81 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 81

Advancing to step 3:
If we divide 118 by 81, we get 1 and a remainder of 37.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 81 from 118 leaves us with 37.
Grab the next digit (4) from the dividend, add it to 37, then carry on: 374 / 81

Moving on to step 4:
The number 81 fits into 374 4 times, leaving a remainder of 50.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 324 from 374, we get 50.
Take the next digit (5) from the dividend and append it to 50, then repeat: 505 / 81

Going ahead to step 5:
81 can be fit into 505 6 times, resulting in a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 146.0
If we take 486 away from 505, we end up with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 81

Advancing to step 6:
81 goes into 198 2 times with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 1462.0
Deduct 162 from 198 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
81 goes into 360 4 times with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 1462.4
If we take 324 away from 360, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
The number 81 fits into 360 4 times, leaving a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 1462.44
Subtract 324 from 360 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.

After the division, we end up with 1462.44 and a remainder of 0.036.
