528811 ÷ 45 
We want to figure out the number of times 528811 can be divided by 45.

On to step 1:
The number 45 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 45

Let's proceed to step 2:
The number 45 fits into 52 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 45 from 52 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 45

Let's proceed to step 3:
45 can be fit into 78 1 times, resulting in a remainder of 33.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 45 from 78 and we're left with 33.
Grab the next digit (8) from the dividend, add it to 33, then carry on: 338 / 45

Let's proceed to step 4:
If we divide 338 by 45, we get 7 and a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 117.0
The remainder is 23 after subtracting 315 from 338.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 45

Advancing to step 5:
When dividing 231 by 45, we get 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 1175.0
If we take 225 away from 231, we end up with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 45

Let's proceed to step 6:
The number 45 fits into 61 1 times, leaving a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 11751.0
Subtract 45 from 61 to 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.

Moving on to step 7:
If we divide 160 by 45, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 11751.3
If we take 135 away from 160, we end up with 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 8:
250 divided by 45 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 11751.35
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
The number 45 fits into 250 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 11751.355
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.

The final outcome is 11751.355, with a leftover of 0.0025.
