871688 divided by 45 
We want to divide 871688 by 45.

Going ahead to step 1:
8 divided by 45 is 0 with 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.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 45

Going ahead to step 2:
87 divided by 45 is 1 with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 45 from 87 to get 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 45

Let's proceed to step 3:
When dividing 421 by 45, we get 9 with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 16 after subtracting 405 from 421.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 45

Let's proceed to step 4:
If we divide 166 by 45, we get 3 and a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 193.0
If we subtract 135 from 166, we get 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 45

Moving on to step 5:
When dividing 318 by 45, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 1937.0
Subtract 315 from 318 to get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 45

Step 6:
45 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 19370.0
Deduct 0 from 38 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
45 goes into 380 8 times with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 19370.8
If we take 360 away from 380, 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 8:
45 can be fit into 200 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 19370.84
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.

On to step 9:
45 can be fit into 200 4 times, resulting in a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 19370.844
Subtract 180 from 200 to get 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 19370.844 with a balance of 0.002.
