We look at the division of 873509 by 97 
We're looking to find how many times 97 goes into 873509.

Advancing to step 1:
If we divide 8 by 97, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 97

Advancing to step 2:
The number 97 fits into 87 0 times, leaving a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Fetch the next digit (3) from the dividend, attach it to 87 and continue: 873 / 97

Going ahead to step 3:
97 goes into 873 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 873 from 873 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 97

Step 4:
97 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 97

Let's proceed to step 5:
50 divided by 97 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 900.0
Subtract 0 from 50 to get 50.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 97

Moving on to step 6:
When dividing 509 by 97, we get 5 with a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 9005.0
Subtracting 485 from 509 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
When dividing 240 by 97, we get 2 with a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 9005.2
Subtracting 194 from 240 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
When dividing 460 by 97, we get 4 with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 9005.24
If we subtract 388 from 460, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
If we divide 720 by 97, we get 7 and a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 9005.247
Subtracting 679 from 720 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 10:
When dividing 410 by 97, we get 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 9005.2474
Subtracting 388 from 410 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
220 divided by 97 is 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 9005.24742
If we take 194 away from 220, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 12:
If we divide 260 by 97, we get 2 and a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 9005.247422
The remainder is 66 after subtracting 194 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final result is 9005.247422 with a remainder of 6.6e-06.
