We divide 539519 by 45
Let's see how many times 45 fits into 539519.

Step 1:
If we divide 5 by 45, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 45

Advancing to step 2:
53 divided by 45 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 45 from 53 to get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 45

Moving on to step 3:
45 can be fit into 89 1 times, resulting in a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 44 after subtracting 45 from 89.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 45

Going ahead to step 4:
If we divide 445 by 45, we get 9 and a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 119.0
Deduct 405 from 445 and we're left with 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 45

On to step 5:
When dividing 401 by 45, we get 8 with a remainder of 41.
The next digit of our result is 8. 
Result so far: 1198.0
If we subtract 360 from 401, we get 41.
Append the next digit (9) from the dividend to 41 and continue with: 419 / 45

Advancing to step 6:
419 divided by 45 is 9 with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 11989.0
The remainder is 14 after subtracting 405 from 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
When dividing 140 by 45, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 11989.3
Subtracting 135 from 140 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 8:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 11989.31
If we take 45 away from 50, we end up 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:
The number 45 fits into 50 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 11989.311
If we subtract 45 from 50, we 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.

The final outcome is 11989.311, with a leftover of 0.0005.
