576437 divided by 45 
Let's see how many times 45 fits into 576437.

Moving on to step 1:
45 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 45

On to step 2:
If we divide 57 by 45, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 45 from 57 and we're left with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 45

Going ahead to step 3:
45 goes into 126 2 times with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 90 from 126 and we're left with 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 45

Going ahead to step 4:
45 can be fit into 364 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 128.0
The remainder is 4 after subtracting 360 from 364.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 45

On to step 5:
If we divide 43 by 45, we get 0 and a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 1280.0
Subtract 0 from 43 to get 43.
Include the next digit (7) from the dividend after 43, then repeat: 437 / 45

Step 6:
45 goes into 437 9 times with a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 12809.0
Subtracting 405 from 437 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
When dividing 320 by 45, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 12809.7
Deduct 315 from 320 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 12809.71
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
45 can be fit into 50 1 times, resulting in a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 12809.711
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 12809.711 with a remaining 0.0005.
