987290 divided by 45 
We're looking to find how many times 45 goes into 987290.

Going ahead to step 1:
When dividing 9 by 45, we get 0 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 (8) from the dividend, attach it to 9 and continue: 98 / 45

Moving on to step 2:
45 goes into 98 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 90 from 98, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 45

Moving on to step 3:
45 goes into 87 1 times with a remainder of 42.
The next digit of our result is 1. 
Result so far: 21.0
If we take 45 away from 87, we end up with 42.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 45

Let's proceed to step 4:
45 can be fit into 422 9 times, resulting in a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 219.0
Subtract 405 from 422 to get 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 45

Going ahead to step 5:
The number 45 fits into 179 3 times, leaving a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 2193.0
Subtract 135 from 179 to get 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 45

Moving on to step 6:
45 goes into 440 9 times with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 21939.0
Deduct 405 from 440 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
45 goes into 350 7 times with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 21939.7
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
45 can be fit into 350 7 times, resulting in a remainder of 35.
The next digit of our result is 7. 
Result so far: 21939.77
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 21939.77 with a balance of 0.035.
