We look at the division of 18872508 by 815 
Our goal is to divide 18872508 by 815.

Advancing to step 1:
When dividing 1 by 815, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 815

Going ahead to step 2:
The number 815 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 815

Advancing to step 3:
The number 815 fits into 188 0 times, leaving a remainder of 188.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 188 and we're left with 188.
Take the next digit (7) from the dividend and append it to 188, then repeat: 1887 / 815

Let's proceed to step 4:
If we divide 1887 by 815, we get 2 and a remainder of 257.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1630 away from 1887, we end up with 257.
Fetch the next digit (2) from the dividend, attach it to 257 and continue: 2572 / 815

On to step 5:
When dividing 2572 by 815, we get 3 with a remainder of 127.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 127 after subtracting 2445 from 2572.
Grab the next digit (5) from the dividend, add it to 127, then carry on: 1275 / 815

Moving on to step 6:
1275 divided by 815 is 1 with a remainder of 460.
Put 1 as the next digit of the answer. 
Result so far: 231.0
Deduct 815 from 1275 and we're left with 460.
Bring next digit (0) of the dividend behind the 460 and repeat the process: 4600 / 815

On to step 7:
815 can be fit into 4600 5 times, resulting in a remainder of 525.
Put 5 as the next digit of the answer. 
Result so far: 2315.0
Subtracting 4075 from 4600 leaves us with 525.
Take the next digit (8) from the dividend and append it to 525, then repeat: 5258 / 815

Going ahead to step 8:
5258 divided by 815 is 6 with a remainder of 368.
Use 6 as the next digit of our solution. 
Result so far: 23156.0
If we subtract 4890 from 5258, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 9:
815 can be fit into 3680 4 times, resulting in a remainder of 420.
The next digit of our result is 4. 
Result so far: 23156.4
Deduct 3260 from 3680 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 10:
4200 divided by 815 is 5 with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 23156.45
Subtract 4075 from 4200 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 11:
1250 divided by 815 is 1 with a remainder of 435.
Record the quotient 1 as the next digit in the result. 
Result so far: 23156.451
If we take 815 away from 1250, we end up with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Advancing to step 12:
When dividing 4350 by 815, we get 5 with a remainder of 275.
The next digit of our result is 5. 
Result so far: 23156.4515
Deduct 4075 from 4350 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 13:
If we divide 2750 by 815, we get 3 and a remainder of 305.
The next digit of our result is 3. 
Result so far: 23156.45153
The remainder is 305 after subtracting 2445 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 14:
When dividing 3050 by 815, we get 3 with a remainder of 605.
Record the quotient 3 as the next digit in the result. 
Result so far: 23156.451533
Deduct 2445 from 3050 and we're left with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

After the division, we end up with 23156.451533 and a remainder of 6.05e-05.
