881159 ÷ 45 
We want to divide 881159 by 45.

Going ahead to step 1:
45 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 45

Advancing to step 2:
If we divide 88 by 45, we get 1 and a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 45 from 88 to get 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 45

Advancing to step 3:
If we divide 431 by 45, we get 9 and a remainder of 26.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 405 from 431 and we're left with 26.
Append the next digit (1) from the dividend to 26 and continue with: 261 / 45

Step 4:
If we divide 261 by 45, we get 5 and a remainder of 36.
The next digit of our result is 5. 
Result so far: 195.0
Subtract 225 from 261 to get 36.
Include the next digit (5) from the dividend after 36, then repeat: 365 / 45

On to step 5:
365 divided by 45 is 8 with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 1958.0
Deduct 360 from 365 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 45

Let's proceed to step 6:
The number 45 fits into 59 1 times, leaving a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 19581.0
The remainder is 14 after subtracting 45 from 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
When dividing 140 by 45, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 19581.3
Deduct 135 from 140 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
When dividing 50 by 45, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 19581.31
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
The number 45 fits into 50 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 19581.311
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 19581.311 and a remainder of 0.0005.
