516242 ÷ 45 
We're looking to find how many times 45 goes into 516242.

Step 1:
The number 45 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 45

Step 2:
51 divided by 45 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 45 from 51, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 45

Going ahead to step 3:
66 divided by 45 is 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 45 from 66 leaves us with 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 45

On to step 4:
If we divide 212 by 45, we get 4 and a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 114.0
Subtracting 180 from 212 leaves us with 32.
Include the next digit (4) from the dividend after 32, then repeat: 324 / 45

Going ahead to step 5:
45 can be fit into 324 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 1147.0
Subtracting 315 from 324 leaves us with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 45

Let's proceed to step 6:
If we divide 92 by 45, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 11472.0
Subtract 90 from 92 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
If we divide 20 by 45, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 11472.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
If we divide 200 by 45, we get 4 and a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 11472.04
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.

Moving on to step 9:
If we divide 200 by 45, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 11472.044
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 11472.044, and the remainder is 0.002.
