We're dividing 66503897 by 115 
We're looking to find how many times 115 goes into 66503897.

On to step 1:
6 divided by 115 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 115

On to step 2:
115 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 115

Moving on to step 3:
115 can be fit into 665 5 times, resulting in a remainder of 90.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 575 from 665 leaves us with 90.
Take the next digit (0) from the dividend and append it to 90, then repeat: 900 / 115

Step 4:
When dividing 900 by 115, we get 7 with a remainder of 95.
Write down 7 as next digit of the result. 
Result so far: 57.0
Deduct 805 from 900 and we're left with 95.
Include the next digit (3) from the dividend after 95, then repeat: 953 / 115

Advancing to step 5:
When dividing 953 by 115, we get 8 with a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 578.0
If we subtract 920 from 953, we get 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 115

Advancing to step 6:
If we divide 338 by 115, we get 2 and a remainder of 108.
The next digit of our result is 2. 
Result so far: 5782.0
The remainder is 108 after subtracting 230 from 338.
Include the next digit (9) from the dividend after 108, then repeat: 1089 / 115

Step 7:
1089 divided by 115 is 9 with a remainder of 54.
Write down 9 as next digit of the result. 
Result so far: 57829.0
Deduct 1035 from 1089 and we're left with 54.
Append the next digit (7) from the dividend to 54 and continue with: 547 / 115

Let's proceed to step 8:
If we divide 547 by 115, we get 4 and a remainder of 87.
The number 4 becomes the next digit in our result. 
Result so far: 578294.0
The remainder is 87 after subtracting 460 from 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 9:
115 can be fit into 870 7 times, resulting in a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 578294.7
The remainder is 65 after subtracting 805 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 10:
If we divide 650 by 115, we get 5 and a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 578294.75
If we subtract 575 from 650, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
The number 115 fits into 750 6 times, leaving a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 578294.756
The remainder is 60 after subtracting 690 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
600 divided by 115 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 578294.7565
Deduct 575 from 600 and we're left with 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 13:
250 divided by 115 is 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 578294.75652
Deduct 230 from 250 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
200 divided by 115 is 1 with a remainder of 85.
The number 1 becomes the next digit in our result. 
Result so far: 578294.756521
If we take 115 away from 200, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 15:
The number 115 fits into 850 7 times, leaving a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 578294.7565217
If we subtract 805 from 850, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 16:
When dividing 450 by 115, we get 3 with a remainder of 105.
The number 3 becomes the next digit in our result. 
Result so far: 578294.75652173
If we subtract 345 from 450, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final result is 578294.75652173 with a remainder of 1.05e-07.
