We divide 12103244 by 815
We want to figure out the number of times 12103244 can be divided by 815.

Advancing to step 1:
The number 815 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 815

Moving on to step 2:
The number 815 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 815

On to step 3:
The number 815 fits into 121 0 times, leaving a remainder of 121.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 121 leaves us with 121.
Append the next digit (0) from the dividend to 121 and continue with: 1210 / 815

Moving on to step 4:
If we divide 1210 by 815, we get 1 and a remainder of 395.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 815 from 1210 leaves us with 395.
Bring next digit (3) of the dividend behind the 395 and repeat the process: 3953 / 815

Let's proceed to step 5:
When dividing 3953 by 815, we get 4 with a remainder of 693.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 3260 from 3953 and we're left with 693.
Append the next digit (2) from the dividend to 693 and continue with: 6932 / 815

On to step 6:
When dividing 6932 by 815, we get 8 with a remainder of 412.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
Subtract 6520 from 6932 to get 412.
Append the next digit (4) from the dividend to 412 and continue with: 4124 / 815

Let's proceed to step 7:
When dividing 4124 by 815, we get 5 with a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 1485.0
If we take 4075 away from 4124, we end up with 49.
Fetch the next digit (4) from the dividend, attach it to 49 and continue: 494 / 815

On to step 8:
815 goes into 494 0 times with a remainder of 494.
Put 0 as the next digit of the answer. 
Result so far: 14850.0
Subtract 0 from 494 to get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

On to step 9:
The number 815 fits into 4940 6 times, leaving a remainder of 50.
The next digit of our result is 6. 
Result so far: 14850.6
Subtracting 4890 from 4940 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
When dividing 500 by 815, we get 0 with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 14850.6
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 11:
815 goes into 5000 6 times with a remainder of 110.
Write down 6 as next digit of the result. 
Result so far: 14850.606
Deduct 4890 from 5000 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 12:
When dividing 1100 by 815, we get 1 with a remainder of 285.
Record the quotient 1 as the next digit in the result. 
Result so far: 14850.6061
If we subtract 815 from 1100, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 13:
2850 divided by 815 is 3 with a remainder of 405.
Record the quotient 3 as the next digit in the result. 
Result so far: 14850.60613
If we take 2445 away from 2850, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Advancing to step 14:
4050 divided by 815 is 4 with a remainder of 790.
Record the quotient 4 as the next digit in the result. 
Result so far: 14850.606134
If we subtract 3260 from 4050, we get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Advancing to step 15:
7900 divided by 815 is 9 with a remainder of 565.
The next digit of our result is 9. 
Result so far: 14850.6061349
Subtracting 7335 from 7900 leaves us with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Advancing to step 16:
When dividing 5650 by 815, we get 6 with a remainder of 760.
Record the quotient 6 as the next digit in the result. 
Result so far: 14850.60613496
If we subtract 4890 from 5650, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Our division results in 14850.60613496 with a remaining 7.6e-07.
