919842 ÷ 45 
We want to figure out the number of times 919842 can be divided by 45.

Advancing to step 1:
45 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 45

Advancing to step 2:
91 divided by 45 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 1 after subtracting 90 from 91.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 45

On to step 3:
45 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 20.0
The remainder is 19 after subtracting 0 from 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 45

Let's proceed to step 4:
45 can be fit into 198 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
Subtract 180 from 198 to get 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 45

Moving on to step 5:
45 can be fit into 184 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 2044.0
If we take 180 away from 184, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 45

Going ahead to step 6:
If we divide 42 by 45, we get 0 and a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 20440.0
Deduct 0 from 42 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 7:
45 can be fit into 420 9 times, resulting in a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 20440.9
The remainder is 15 after subtracting 405 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 20440.93
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
45 can be fit into 150 3 times, resulting in a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 20440.933
Subtract 135 from 150 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 20440.933 and a remainder of 0.0015.
