We divide 578495 by 45
We're looking to find how many times 45 goes into 578495.

Moving on 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
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 45

Step 2:
The number 45 fits into 57 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 45 away from 57, we end up with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 45

On to step 3:
The number 45 fits into 128 2 times, leaving a remainder of 38.
The next digit of our result is 2. 
Result so far: 12.0
If we take 90 away from 128, we end up with 38.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 45

Moving on to step 4:
If we divide 384 by 45, we get 8 and a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
The remainder is 24 after subtracting 360 from 384.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 45

Advancing to step 5:
If we divide 249 by 45, we get 5 and a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 1285.0
Deduct 225 from 249 and we're left with 24.
Grab the next digit (5) from the dividend, add it to 24, then carry on: 245 / 45

On to step 6:
245 divided by 45 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 12855.0
If we take 225 away from 245, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
200 divided by 45 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 12855.4
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
45 goes into 200 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 12855.44
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 12855.44 with a remaining 0.02.
