510753 divided by 45 
We want to figure out the number of times 510753 can be divided by 45.

Step 1:
If we divide 5 by 45, we get 0 and 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.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 45

Step 2:
45 goes into 51 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 45 from 51 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 45

Moving on to step 3:
The number 45 fits into 60 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 45 from 60 and we're left with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 45

Let's proceed to step 4:
45 goes into 157 3 times with a remainder of 22.
The next digit of our result is 3. 
Result so far: 113.0
If we take 135 away from 157, we end up with 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 45

Let's proceed to step 5:
The number 45 fits into 225 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1135.0
Deduct 225 from 225 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 45

Let's proceed to step 6:
When dividing 3 by 45, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 11350.0
If we take 0 away from 3, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
If we divide 30 by 45, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 11350.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 11350.06
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
When dividing 300 by 45, we get 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 11350.066
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 11350.066, and the remainder is 0.003.
