Let's divide 558286 by 45
We want to figure out the number of times 558286 can be divided by 45.

Let's proceed to step 1:
When dividing 5 by 45, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 45

On to step 2:
45 can be fit into 55 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 45 from 55, we get 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 45

Let's proceed to step 3:
108 divided by 45 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 90 away from 108, we end up with 18.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 45

Step 4:
182 divided by 45 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 124.0
If we take 180 away from 182, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 45

Going ahead to step 5:
45 can be fit into 28 0 times, resulting in a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 1240.0
Subtracting 0 from 28 leaves us with 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 45

Going ahead to step 6:
286 divided by 45 is 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 12406.0
If we subtract 270 from 286, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
45 goes into 160 3 times with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 12406.3
Subtract 135 from 160 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
45 goes into 250 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 12406.35
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
The number 45 fits into 250 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 12406.355
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 12406.355 and a remainder of 0.0025.
