871573 divided by 84 
Let's see how many times 84 fits into 871573.

Advancing to step 1:
If we divide 8 by 84, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 84

Advancing to step 2:
If we divide 87 by 84, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 84 from 87 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 84

Going ahead to step 3:
31 divided by 84 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 31 to get 31.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 84

On to step 4:
315 divided by 84 is 3 with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 103.0
Subtracting 252 from 315 leaves us with 63.
Append the next digit (7) from the dividend to 63 and continue with: 637 / 84

Going ahead to step 5:
The number 84 fits into 637 7 times, leaving a remainder of 49.
Write down 7 as next digit of the result. 
Result so far: 1037.0
Subtracting 588 from 637 leaves us with 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 84

On to step 6:
84 can be fit into 493 5 times, resulting in a remainder of 73.
The next digit of our result is 5. 
Result so far: 10375.0
If we take 420 away from 493, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 7:
730 divided by 84 is 8 with a remainder of 58.
The next digit of our result is 8. 
Result so far: 10375.8
The remainder is 58 after subtracting 672 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
580 divided by 84 is 6 with a remainder of 76.
The next digit of our result is 6. 
Result so far: 10375.86
Subtracting 504 from 580 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 9:
84 goes into 760 9 times with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 10375.869
If we take 756 away from 760, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
If we divide 40 by 84, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10375.869
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
The number 84 fits into 400 4 times, leaving a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 10375.86904
If we subtract 336 from 400, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
84 goes into 640 7 times with a remainder of 52.
The next digit of our result is 7. 
Result so far: 10375.869047
Subtracting 588 from 640 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 13:
84 goes into 520 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 10375.8690476
If we take 504 away from 520, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
84 can be fit into 160 1 times, resulting in a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 10375.86904761
Subtracting 84 from 160 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 10375.86904761 with a balance of 7.6e-08.
