Let's divide 429840 by 45
We want to figure out the number of times 429840 can be divided by 45.

Let's proceed to step 1:
The number 45 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 45

Let's proceed to step 2:
42 divided by 45 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 45

On to step 3:
The number 45 fits into 429 9 times, leaving a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 405 away from 429, we end up with 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 45

On to step 4:
The number 45 fits into 248 5 times, leaving a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 95.0
The remainder is 23 after subtracting 225 from 248.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 45

Going ahead to step 5:
The number 45 fits into 234 5 times, leaving a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 955.0
If we take 225 away from 234, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 45

On to step 6:
90 divided by 45 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 9552.0
Deduct 90 from 90 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
45 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9552.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
45 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9552.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 9552.0, with a leftover of 0.0.
