Let's divide 12530983 by 815
We're looking to find how many times 815 goes into 12530983.

Advancing to step 1:
The number 815 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 815

Moving on to step 2:
The number 815 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 815

On to step 3:
125 divided by 815 is 0 with a remainder of 125.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 125, we end up with 125.
Bring next digit (3) of the dividend behind the 125 and repeat the process: 1253 / 815

Moving on to step 4:
1253 divided by 815 is 1 with a remainder of 438.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 815 away from 1253, we end up with 438.
Include the next digit (0) from the dividend after 438, then repeat: 4380 / 815

Let's proceed to step 5:
815 goes into 4380 5 times with a remainder of 305.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 305 after subtracting 4075 from 4380.
Include the next digit (9) from the dividend after 305, then repeat: 3059 / 815

Step 6:
When dividing 3059 by 815, we get 3 with a remainder of 614.
Put 3 as the next digit of the answer. 
Result so far: 153.0
If we subtract 2445 from 3059, we get 614.
Grab the next digit (8) from the dividend, add it to 614, then carry on: 6148 / 815

Going ahead to step 7:
If we divide 6148 by 815, we get 7 and a remainder of 443.
Use 7 as the next digit of our solution. 
Result so far: 1537.0
The remainder is 443 after subtracting 5705 from 6148.
Fetch the next digit (3) from the dividend, attach it to 443 and continue: 4433 / 815

Advancing to step 8:
If we divide 4433 by 815, we get 5 and a remainder of 358.
The number 5 becomes the next digit in our result. 
Result so far: 15375.0
If we subtract 4075 from 4433, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Moving on to step 9:
815 goes into 3580 4 times with a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 15375.4
If we take 3260 away from 3580, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 10:
The number 815 fits into 3200 3 times, leaving a remainder of 755.
Record the quotient 3 as the next digit in the result. 
Result so far: 15375.43
Subtract 2445 from 3200 to get 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Moving on to step 11:
7550 divided by 815 is 9 with a remainder of 215.
Use 9 as the next digit of our solution. 
Result so far: 15375.439
If we subtract 7335 from 7550, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 12:
2150 divided by 815 is 2 with a remainder of 520.
The number 2 becomes the next digit in our result. 
Result so far: 15375.4392
The remainder is 520 after subtracting 1630 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 13:
5200 divided by 815 is 6 with a remainder of 310.
Record the quotient 6 as the next digit in the result. 
Result so far: 15375.43926
If we subtract 4890 from 5200, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 14:
815 can be fit into 3100 3 times, resulting in a remainder of 655.
The number 3 becomes the next digit in our result. 
Result so far: 15375.439263
If we subtract 2445 from 3100, we get 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Moving on to step 15:
The number 815 fits into 6550 8 times, leaving a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 15375.4392638
Deduct 6520 from 6550 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 16:
815 can be fit into 300 0 times, resulting in a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 15375.4392638
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 15375.4392638 with a remaining 3e-07.
