Let's divide 45099 by 81
Let's see how many times 81 fits into 45099.

Going ahead to step 1:
If we divide 4 by 81, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 81

Advancing to step 2:
81 goes into 45 0 times with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Grab the next digit (0) from the dividend, add it to 45, then carry on: 450 / 81

Moving on to step 3:
When dividing 450 by 81, we get 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 405 from 450 to get 45.
Take the next digit (9) from the dividend and append it to 45, then repeat: 459 / 81

Step 4:
The number 81 fits into 459 5 times, leaving a remainder of 54.
The next digit of our result is 5. 
Result so far: 55.0
Deduct 405 from 459 and we're left with 54.
Grab the next digit (9) from the dividend, add it to 54, then carry on: 549 / 81

Advancing to step 5:
81 goes into 549 6 times with a remainder of 63.
Write down 6 as next digit of the result. 
Result so far: 556.0
Subtract 486 from 549 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 6:
81 can be fit into 630 7 times, resulting in a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 556.7
Subtracting 567 from 630 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
If we divide 630 by 81, we get 7 and a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 556.77
If we subtract 567 from 630, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final result is 556.77 with a remainder of 0.063.
