987669 divided by 45 
We want to figure out the number of times 987669 can be divided by 45.

On to step 1:
9 divided by 45 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 45

Let's proceed to step 2:
If we divide 98 by 45, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 90 from 98 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 45

Let's proceed to step 3:
87 divided by 45 is 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 45 from 87, we get 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 45

Step 4:
If we divide 426 by 45, we get 9 and a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 219.0
Deduct 405 from 426 and we're left with 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 45

Moving on to step 5:
45 goes into 216 4 times with a remainder of 36.
The next digit of our result is 4. 
Result so far: 2194.0
If we subtract 180 from 216, we get 36.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 45

Advancing to step 6:
The number 45 fits into 369 8 times, leaving a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 21948.0
Subtract 360 from 369 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
45 goes into 90 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 21948.2
Subtract 90 from 90 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:
The number 45 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 21948.2
Deduct 0 from 0 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.

On to step 9:
0 divided by 45 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 21948.2
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.

After the division, we end up with 21948.2 and a remainder of 0.0.
