81825055 divided by 870 
Our goal is to divide 81825055 by 870.

Step 1:
870 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 870

Going ahead to step 2:
870 goes into 81 0 times with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Append the next digit (8) from the dividend to 81 and continue with: 818 / 870

Advancing to step 3:
818 divided by 870 is 0 with a remainder of 818.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 818 leaves us with 818.
Bring next digit (2) of the dividend behind the 818 and repeat the process: 8182 / 870

Advancing to step 4:
When dividing 8182 by 870, we get 9 with a remainder of 352.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7830 from 8182 leaves us with 352.
Include the next digit (5) from the dividend after 352, then repeat: 3525 / 870

Going ahead to step 5:
If we divide 3525 by 870, we get 4 and a remainder of 45.
Put 4 as the next digit of the answer. 
Result so far: 94.0
Subtracting 3480 from 3525 leaves us with 45.
Bring next digit (0) of the dividend behind the 45 and repeat the process: 450 / 870

Moving on to step 6:
If we divide 450 by 870, we get 0 and a remainder of 450.
Use 0 as the next digit of our solution. 
Result so far: 940.0
Subtract 0 from 450 to get 450.
Include the next digit (5) from the dividend after 450, then repeat: 4505 / 870

Step 7:
870 can be fit into 4505 5 times, resulting in a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 9405.0
If we subtract 4350 from 4505, we get 155.
Fetch the next digit (5) from the dividend, attach it to 155 and continue: 1555 / 870

Going ahead to step 8:
If we divide 1555 by 870, we get 1 and a remainder of 685.
Record the quotient 1 as the next digit in the result. 
Result so far: 94051.0
The remainder is 685 after subtracting 870 from 1555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Moving on to step 9:
870 goes into 6850 7 times with a remainder of 760.
Write down 7 as next digit of the result. 
Result so far: 94051.7
Subtract 6090 from 6850 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 10:
When dividing 7600 by 870, we get 8 with a remainder of 640.
Put 8 as the next digit of the answer. 
Result so far: 94051.78
The remainder is 640 after subtracting 6960 from 7600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 11:
If we divide 6400 by 870, we get 7 and a remainder of 310.
The number 7 becomes the next digit in our result. 
Result so far: 94051.787
If we subtract 6090 from 6400, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 12:
If we divide 3100 by 870, we get 3 and a remainder of 490.
Record the quotient 3 as the next digit in the result. 
Result so far: 94051.7873
The remainder is 490 after subtracting 2610 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 13:
4900 divided by 870 is 5 with a remainder of 550.
The number 5 becomes the next digit in our result. 
Result so far: 94051.78735
Deduct 4350 from 4900 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 14:
870 goes into 5500 6 times with a remainder of 280.
Write down 6 as next digit of the result. 
Result so far: 94051.787356
Subtract 5220 from 5500 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 15:
2800 divided by 870 is 3 with a remainder of 190.
The next digit of our result is 3. 
Result so far: 94051.7873563
If we take 2610 away from 2800, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 16:
870 can be fit into 1900 2 times, resulting in a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 94051.78735632
Subtracting 1740 from 1900 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

In conclusion, the division gives 94051.78735632 with a balance of 1.6e-07.
