Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 870

Moving on to step 2:
82 divided by 870 is 0 with a remainder of 82.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 82 after subtracting 0 from 82.
Fetch the next digit (1) from the dividend, attach it to 82 and continue: 821 / 870

Advancing to step 3:
870 goes into 821 0 times with a remainder of 821.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 821 after subtracting 0 from 821.
Fetch the next digit (7) from the dividend, attach it to 821 and continue: 8217 / 870

Moving on to step 4:
If we divide 8217 by 870, we get 9 and a remainder of 387.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 7830 from 8217 to get 387.
Append the next digit (3) from the dividend to 387 and continue with: 3873 / 870

Moving on to step 5:
The number 870 fits into 3873 4 times, leaving a remainder of 393.
Use 4 as the next digit of our solution. 
Result so far: 94.0
Deduct 3480 from 3873 and we're left with 393.
Fetch the next digit (2) from the dividend, attach it to 393 and continue: 3932 / 870

Advancing to step 6:
The number 870 fits into 3932 4 times, leaving a remainder of 452.
Write down 4 as next digit of the result. 
Result so far: 944.0
Deduct 3480 from 3932 and we're left with 452.
Grab the next digit (5) from the dividend, add it to 452, then carry on: 4525 / 870

Step 7:
870 can be fit into 4525 5 times, resulting in a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 9445.0
The remainder is 175 after subtracting 4350 from 4525.
Append the next digit (8) from the dividend to 175 and continue with: 1758 / 870

Moving on to step 8:
When dividing 1758 by 870, we get 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 94452.0
Subtracting 1740 from 1758 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
870 goes into 180 0 times with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 94452.0
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
1800 divided by 870 is 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 94452.02
Subtract 1740 from 1800 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
600 divided by 870 is 0 with a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 94452.02
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 12:
The number 870 fits into 6000 6 times, leaving a remainder of 780.
The next digit of our result is 6. 
Result so far: 94452.0206
Deduct 5220 from 6000 and we're left with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Let's proceed to step 13:
870 can be fit into 7800 8 times, resulting in a remainder of 840.
The next digit of our result is 8. 
Result so far: 94452.02068
If we subtract 6960 from 7800, we get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Moving on to step 14:
870 goes into 8400 9 times with a remainder of 570.
Use 9 as the next digit of our solution. 
Result so far: 94452.020689
Subtract 7830 from 8400 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Let's proceed to step 15:
870 goes into 5700 6 times with a remainder of 480.
Put 6 as the next digit of the answer. 
Result so far: 94452.0206896
If we take 5220 away from 5700, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 16:
870 can be fit into 4800 5 times, resulting in a remainder of 450.
Put 5 as the next digit of the answer. 
Result so far: 94452.02068965
Subtracting 4350 from 4800 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Our division results in 94452.02068965 with a remaining 4.5e-07.
