71023753 divided by 873 
Our goal is to divide 71023753 by 873.

Step 1:
When dividing 7 by 873, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 873

On to step 2:
71 divided by 873 is 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Append the next digit (0) from the dividend to 71 and continue with: 710 / 873

Let's proceed to step 3:
The number 873 fits into 710 0 times, leaving a remainder of 710.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 710, we end up with 710.
Grab the next digit (2) from the dividend, add it to 710, then carry on: 7102 / 873

Going ahead to step 4:
When dividing 7102 by 873, we get 8 with a remainder of 118.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 6984 from 7102 to get 118.
Bring next digit (3) of the dividend behind the 118 and repeat the process: 1183 / 873

Moving on to step 5:
873 can be fit into 1183 1 times, resulting in a remainder of 310.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Deduct 873 from 1183 and we're left with 310.
Fetch the next digit (7) from the dividend, attach it to 310 and continue: 3107 / 873

Let's proceed to step 6:
3107 divided by 873 is 3 with a remainder of 488.
The number 3 becomes the next digit in our result. 
Result so far: 813.0
If we take 2619 away from 3107, we end up with 488.
Append the next digit (5) from the dividend to 488 and continue with: 4885 / 873

Going ahead to step 7:
873 can be fit into 4885 5 times, resulting in a remainder of 520.
The next digit of our result is 5. 
Result so far: 8135.0
Deduct 4365 from 4885 and we're left with 520.
Include the next digit (3) from the dividend after 520, then repeat: 5203 / 873

Step 8:
5203 divided by 873 is 5 with a remainder of 838.
Record the quotient 5 as the next digit in the result. 
Result so far: 81355.0
If we subtract 4365 from 5203, we get 838.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8380, and continue the process.

Going ahead to step 9:
873 can be fit into 8380 9 times, resulting in a remainder of 523.
The number 9 becomes the next digit in our result. 
Result so far: 81355.9
If we take 7857 away from 8380, we end up with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Step 10:
When dividing 5230 by 873, we get 5 with a remainder of 865.
Put 5 as the next digit of the answer. 
Result so far: 81355.95
Deduct 4365 from 5230 and we're left with 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

Moving on to step 11:
The number 873 fits into 8650 9 times, leaving a remainder of 793.
Use 9 as the next digit of our solution. 
Result so far: 81355.959
The remainder is 793 after subtracting 7857 from 8650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Moving on to step 12:
873 can be fit into 7930 9 times, resulting in a remainder of 73.
Put 9 as the next digit of the answer. 
Result so far: 81355.9599
The remainder is 73 after subtracting 7857 from 7930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The quotient of the division is 81355.9599, and the remainder is 0.00073.
