812171 ÷ 87 
Our goal is to divide 812171 by 87.

Moving on to step 1:
8 divided by 87 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 87

Let's proceed to step 2:
87 can be fit into 81 0 times, resulting in a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Grab the next digit (2) from the dividend, add it to 81, then carry on: 812 / 87

On to step 3:
812 divided by 87 is 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 783 from 812, we get 29.
Include the next digit (1) from the dividend after 29, then repeat: 291 / 87

Let's proceed to step 4:
The number 87 fits into 291 3 times, leaving a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 93.0
The remainder is 30 after subtracting 261 from 291.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 87

Let's proceed to step 5:
87 can be fit into 307 3 times, resulting in a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 933.0
If we take 261 away from 307, we end up with 46.
Bring next digit (1) of the dividend behind the 46 and repeat the process: 461 / 87

Step 6:
The number 87 fits into 461 5 times, leaving a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 9335.0
Subtracting 435 from 461 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
87 can be fit into 260 2 times, resulting in a remainder of 86.
The next digit of our result is 2. 
Result so far: 9335.2
Subtract 174 from 260 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 8:
The number 87 fits into 860 9 times, leaving a remainder of 77.
Put 9 as the next digit of the answer. 
Result so far: 9335.29
If we take 783 away from 860, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 9:
If we divide 770 by 87, we get 8 and a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 9335.298
Subtract 696 from 770 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 10:
When dividing 740 by 87, we get 8 with a remainder of 44.
The next digit of our result is 8. 
Result so far: 9335.2988
Subtracting 696 from 740 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 9335.2988 with a balance of 0.00044.
