We're dividing 30230172 by 873 
Our goal is to divide 30230172 by 873.

Going ahead to step 1:
The number 873 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 873

Advancing to step 2:
If we divide 30 by 873, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 873

Going ahead to step 3:
When dividing 302 by 873, we get 0 with a remainder of 302.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 302 after subtracting 0 from 302.
Include the next digit (3) from the dividend after 302, then repeat: 3023 / 873

Let's proceed to step 4:
3023 divided by 873 is 3 with a remainder of 404.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 2619 from 3023 to get 404.
Append the next digit (0) from the dividend to 404 and continue with: 4040 / 873

Going ahead to step 5:
873 goes into 4040 4 times with a remainder of 548.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we take 3492 away from 4040, we end up with 548.
Include the next digit (1) from the dividend after 548, then repeat: 5481 / 873

On to step 6:
5481 divided by 873 is 6 with a remainder of 243.
Use 6 as the next digit of our solution. 
Result so far: 346.0
If we subtract 5238 from 5481, we get 243.
Fetch the next digit (7) from the dividend, attach it to 243 and continue: 2437 / 873

On to step 7:
If we divide 2437 by 873, we get 2 and a remainder of 691.
Write down 2 as next digit of the result. 
Result so far: 3462.0
Deduct 1746 from 2437 and we're left with 691.
Bring next digit (2) of the dividend behind the 691 and repeat the process: 6912 / 873

Moving on to step 8:
6912 divided by 873 is 7 with a remainder of 801.
Record the quotient 7 as the next digit in the result. 
Result so far: 34627.0
The remainder is 801 after subtracting 6111 from 6912.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8010, and continue the process.

Going ahead to step 9:
The number 873 fits into 8010 9 times, leaving a remainder of 153.
The number 9 becomes the next digit in our result. 
Result so far: 34627.9
If we take 7857 away from 8010, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 10:
873 can be fit into 1530 1 times, resulting in a remainder of 657.
Write down 1 as next digit of the result. 
Result so far: 34627.91
Subtracting 873 from 1530 leaves us with 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

On to step 11:
873 can be fit into 6570 7 times, resulting in a remainder of 459.
The number 7 becomes the next digit in our result. 
Result so far: 34627.917
The remainder is 459 after subtracting 6111 from 6570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Moving on to step 12:
The number 873 fits into 4590 5 times, leaving a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 34627.9175
Subtracting 4365 from 4590 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 13:
The number 873 fits into 2250 2 times, leaving a remainder of 504.
The next digit of our result is 2. 
Result so far: 34627.91752
Subtract 1746 from 2250 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 14:
873 can be fit into 5040 5 times, resulting in a remainder of 675.
The number 5 becomes the next digit in our result. 
Result so far: 34627.917525
Subtracting 4365 from 5040 leaves us with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Advancing to step 15:
If we divide 6750 by 873, we get 7 and a remainder of 639.
Put 7 as the next digit of the answer. 
Result so far: 34627.9175257
Subtract 6111 from 6750 to get 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Going ahead to step 16:
If we divide 6390 by 873, we get 7 and a remainder of 279.
The number 7 becomes the next digit in our result. 
Result so far: 34627.91752577
Subtracting 6111 from 6390 leaves us with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

The final result is 34627.91752577 with a remainder of 2.79e-07.
