We look at the division of 78565988 by 873 
Our goal is to divide 78565988 by 873.

Step 1:
If we divide 7 by 873, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 873

Moving on to step 2:
78 divided by 873 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (5) of the dividend behind the 78 and repeat the process: 785 / 873

Going ahead to step 3:
873 can be fit into 785 0 times, resulting in a remainder of 785.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 785 after subtracting 0 from 785.
Append the next digit (6) from the dividend to 785 and continue with: 7856 / 873

Going ahead to step 4:
7856 divided by 873 is 8 with a remainder of 872.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 872 after subtracting 6984 from 7856.
Bring next digit (5) of the dividend behind the 872 and repeat the process: 8725 / 873

Going ahead to step 5:
If we divide 8725 by 873, we get 9 and a remainder of 868.
The next digit of our result is 9. 
Result so far: 89.0
If we subtract 7857 from 8725, we get 868.
Fetch the next digit (9) from the dividend, attach it to 868 and continue: 8689 / 873

Moving on to step 6:
8689 divided by 873 is 9 with a remainder of 832.
Use 9 as the next digit of our solution. 
Result so far: 899.0
Subtracting 7857 from 8689 leaves us with 832.
Append the next digit (8) from the dividend to 832 and continue with: 8328 / 873

Moving on to step 7:
873 can be fit into 8328 9 times, resulting in a remainder of 471.
Write down 9 as next digit of the result. 
Result so far: 8999.0
If we take 7857 away from 8328, we end up with 471.
Grab the next digit (8) from the dividend, add it to 471, then carry on: 4718 / 873

Advancing to step 8:
873 goes into 4718 5 times with a remainder of 353.
Use 5 as the next digit of our solution. 
Result so far: 89995.0
Deduct 4365 from 4718 and we're left with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Advancing to step 9:
The number 873 fits into 3530 4 times, leaving a remainder of 38.
The next digit of our result is 4. 
Result so far: 89995.4
Subtract 3492 from 3530 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
380 divided by 873 is 0 with a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 89995.4
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 11:
When dividing 3800 by 873, we get 4 with a remainder of 308.
The next digit of our result is 4. 
Result so far: 89995.404
If we subtract 3492 from 3800, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 12:
873 can be fit into 3080 3 times, resulting in a remainder of 461.
The number 3 becomes the next digit in our result. 
Result so far: 89995.4043
The remainder is 461 after subtracting 2619 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Step 13:
4610 divided by 873 is 5 with a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 89995.40435
The remainder is 245 after subtracting 4365 from 4610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 14:
873 can be fit into 2450 2 times, resulting in a remainder of 704.
The next digit of our result is 2. 
Result so far: 89995.404352
The remainder is 704 after subtracting 1746 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Let's proceed to step 15:
873 goes into 7040 8 times with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 89995.4043528
Subtract 6984 from 7040 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 16:
When dividing 560 by 873, we get 0 with a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 89995.4043528
Subtracting 0 from 560 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The final result is 89995.4043528 with a remainder of 5.6e-07.
