Let's divide 74645390 by 45
We're looking to find how many times 45 goes into 74645390.

On to step 1:
When dividing 7 by 45, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 45

Going ahead to step 2:
45 goes into 74 1 times with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 29 after subtracting 45 from 74.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 45

Moving on to step 3:
296 divided by 45 is 6 with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 270 from 296 and we're left with 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 45

Step 4:
264 divided by 45 is 5 with a remainder of 39.
Write down 5 as next digit of the result. 
Result so far: 165.0
If we subtract 225 from 264, we get 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 45

On to step 5:
If we divide 395 by 45, we get 8 and a remainder of 35.
The next digit of our result is 8. 
Result so far: 1658.0
Deduct 360 from 395 and we're left with 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 45

Step 6:
The number 45 fits into 353 7 times, leaving a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 16587.0
If we take 315 away from 353, we end up with 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 45

On to step 7:
If we divide 389 by 45, we get 8 and a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 165878.0
Subtracting 360 from 389 leaves us with 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 45

On to step 8:
The number 45 fits into 290 6 times, leaving a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 1658786.0
If we take 270 away from 290, we end up with 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 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: 1658786.4
Deduct 180 from 200 and we're left with 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 10:
If we divide 200 by 45, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 1658786.44
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 1658786.44 with a balance of 0.02.
