876990 divided by 45 
We want to figure out the number of times 876990 can be divided by 45.

Step 1:
45 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 45

Moving on to step 2:
87 divided by 45 is 1 with a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 45 from 87 leaves us with 42.
Grab the next digit (6) from the dividend, add it to 42, then carry on: 426 / 45

Step 3:
45 can be fit into 426 9 times, resulting in a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 405 from 426 to get 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 45

Going ahead to step 4:
45 can be fit into 219 4 times, resulting in a remainder of 39.
The next digit of our result is 4. 
Result so far: 194.0
The remainder is 39 after subtracting 180 from 219.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 45

Let's proceed to step 5:
If we divide 399 by 45, we get 8 and a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 1948.0
Deduct 360 from 399 and we're left with 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 45

Moving on to step 6:
390 divided by 45 is 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 19488.0
Subtracting 360 from 390 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
When dividing 300 by 45, we get 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 19488.6
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
300 divided by 45 is 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 19488.66
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 19488.66, and the remainder is 0.03.
