We're dividing 45866 by 99 
We want to divide 45866 by 99.

Step 1:
99 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 99

Advancing to step 2:
When dividing 45 by 99, we get 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 99

On to step 3:
99 can be fit into 458 4 times, resulting in a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 396 from 458 and we're left with 62.
Include the next digit (6) from the dividend after 62, then repeat: 626 / 99

On to step 4:
If we divide 626 by 99, we get 6 and a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we subtract 594 from 626, we get 32.
Append the next digit (6) from the dividend to 32 and continue with: 326 / 99

Let's proceed to step 5:
If we divide 326 by 99, we get 3 and a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 463.0
Deduct 297 from 326 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 6:
When dividing 290 by 99, we get 2 with a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 463.2
If we subtract 198 from 290, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 7:
When dividing 920 by 99, we get 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 463.29
Subtracting 891 from 920 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 8:
99 can be fit into 290 2 times, resulting in a remainder of 92.
The next digit of our result is 2. 
Result so far: 463.292
Subtracting 198 from 290 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 9:
The number 99 fits into 920 9 times, leaving a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 463.2929
Deduct 891 from 920 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
When dividing 290 by 99, we get 2 with a remainder of 92.
Use 2 as the next digit of our solution. 
Result so far: 463.29292
Subtracting 198 from 290 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 11:
920 divided by 99 is 9 with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 463.292929
If we take 891 away from 920, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 12:
99 goes into 290 2 times with a remainder of 92.
Put 2 as the next digit of the answer. 
Result so far: 463.2929292
Deduct 198 from 290 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 13:
The number 99 fits into 920 9 times, leaving a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 463.29292929
Deduct 891 from 920 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final result is 463.29292929 with a remainder of 2.9e-08.
