829990 ÷ 45 
We're looking to find how many times 45 goes into 829990.

Let's proceed to step 1:
45 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 45

Step 2:
The number 45 fits into 82 1 times, leaving a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 45 from 82 to get 37.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 45

Going ahead to step 3:
379 divided by 45 is 8 with a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 360 from 379, we get 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 45

Moving on to step 4:
45 can be fit into 199 4 times, resulting in a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 184.0
Subtracting 180 from 199 leaves us with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 45

Going ahead to step 5:
The number 45 fits into 199 4 times, leaving a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 1844.0
If we subtract 180 from 199, we get 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 45

Moving on to step 6:
190 divided by 45 is 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 18444.0
Subtracting 180 from 190 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
100 divided by 45 is 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 18444.2
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 45, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 18444.22
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 18444.22 with a balance of 0.01.
