Let's see how many times 873 fits into 78053209.

On to step 1:
When dividing 7 by 873, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 873

On to step 2:
873 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (0) from the dividend to 78 and continue with: 780 / 873

Step 3:
The number 873 fits into 780 0 times, leaving a remainder of 780.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 780 after subtracting 0 from 780.
Fetch the next digit (5) from the dividend, attach it to 780 and continue: 7805 / 873

Going ahead to step 4:
7805 divided by 873 is 8 with a remainder of 821.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 821 after subtracting 6984 from 7805.
Fetch the next digit (3) from the dividend, attach it to 821 and continue: 8213 / 873

Going ahead to step 5:
The number 873 fits into 8213 9 times, leaving a remainder of 356.
Put 9 as the next digit of the answer. 
Result so far: 89.0
Deduct 7857 from 8213 and we're left with 356.
Fetch the next digit (2) from the dividend, attach it to 356 and continue: 3562 / 873

On to step 6:
The number 873 fits into 3562 4 times, leaving a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 894.0
Subtract 3492 from 3562 to get 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 873

Going ahead to step 7:
The number 873 fits into 700 0 times, leaving a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 8940.0
If we subtract 0 from 700, we get 700.
Grab the next digit (9) from the dividend, add it to 700, then carry on: 7009 / 873

Let's proceed to step 8:
7009 divided by 873 is 8 with a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 89408.0
Subtract 6984 from 7009 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
The number 873 fits into 250 0 times, leaving a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 89408.0
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 10:
The number 873 fits into 2500 2 times, leaving a remainder of 754.
Record the quotient 2 as the next digit in the result. 
Result so far: 89408.02
If we subtract 1746 from 2500, we get 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Going ahead to step 11:
873 goes into 7540 8 times with a remainder of 556.
Use 8 as the next digit of our solution. 
Result so far: 89408.028
Subtracting 6984 from 7540 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

On to step 12:
When dividing 5560 by 873, we get 6 with a remainder of 322.
The next digit of our result is 6. 
Result so far: 89408.0286
The remainder is 322 after subtracting 5238 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 13:
The number 873 fits into 3220 3 times, leaving a remainder of 601.
The number 3 becomes the next digit in our result. 
Result so far: 89408.02863
If we take 2619 away from 3220, we end up with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Let's proceed to step 14:
873 can be fit into 6010 6 times, resulting in a remainder of 772.
Use 6 as the next digit of our solution. 
Result so far: 89408.028636
The remainder is 772 after subtracting 5238 from 6010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Step 15:
If we divide 7720 by 873, we get 8 and a remainder of 736.
The next digit of our result is 8. 
Result so far: 89408.0286368
Subtracting 6984 from 7720 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Moving on to step 16:
The number 873 fits into 7360 8 times, leaving a remainder of 376.
The next digit of our result is 8. 
Result so far: 89408.02863688
If we subtract 6984 from 7360, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The quotient of the division is 89408.02863688, and the remainder is 3.76e-07.
