12315652 ÷ 819 
Our goal is to divide 12315652 by 819.

Moving on to step 1:
The number 819 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 819

Let's proceed to step 2:
819 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 819

Step 3:
If we divide 123 by 819, we get 0 and a remainder of 123.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 123, we end up with 123.
Append the next digit (1) from the dividend to 123 and continue with: 1231 / 819

Going ahead to step 4:
1231 divided by 819 is 1 with a remainder of 412.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 412 after subtracting 819 from 1231.
Include the next digit (5) from the dividend after 412, then repeat: 4125 / 819

Let's proceed to step 5:
4125 divided by 819 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 4095 away from 4125, we end up with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 819

Going ahead to step 6:
When dividing 306 by 819, we get 0 with a remainder of 306.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Subtract 0 from 306 to get 306.
Grab the next digit (5) from the dividend, add it to 306, then carry on: 3065 / 819

Step 7:
819 can be fit into 3065 3 times, resulting in a remainder of 608.
Write down 3 as next digit of the result. 
Result so far: 1503.0
If we take 2457 away from 3065, we end up with 608.
Fetch the next digit (2) from the dividend, attach it to 608 and continue: 6082 / 819

Let's proceed to step 8:
819 can be fit into 6082 7 times, resulting in a remainder of 349.
Put 7 as the next digit of the answer. 
Result so far: 15037.0
If we subtract 5733 from 6082, we get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Advancing to step 9:
819 can be fit into 3490 4 times, resulting in a remainder of 214.
The next digit of our result is 4. 
Result so far: 15037.4
Subtracting 3276 from 3490 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 10:
2140 divided by 819 is 2 with a remainder of 502.
Use 2 as the next digit of our solution. 
Result so far: 15037.42
Subtracting 1638 from 2140 leaves us with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Advancing to step 11:
When dividing 5020 by 819, we get 6 with a remainder of 106.
Put 6 as the next digit of the answer. 
Result so far: 15037.426
If we take 4914 away from 5020, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 12:
819 can be fit into 1060 1 times, resulting in a remainder of 241.
Write down 1 as next digit of the result. 
Result so far: 15037.4261
Deduct 819 from 1060 and we're left with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Let's proceed to step 13:
The number 819 fits into 2410 2 times, leaving a remainder of 772.
Put 2 as the next digit of the answer. 
Result so far: 15037.42612
Subtract 1638 from 2410 to get 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

On to step 14:
7720 divided by 819 is 9 with a remainder of 349.
Record the quotient 9 as the next digit in the result. 
Result so far: 15037.426129
If we subtract 7371 from 7720, we get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Moving on to step 15:
819 goes into 3490 4 times with a remainder of 214.
Write down 4 as next digit of the result. 
Result so far: 15037.4261294
Deduct 3276 from 3490 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 16:
When dividing 2140 by 819, we get 2 with a remainder of 502.
Write down 2 as next digit of the result. 
Result so far: 15037.42612942
Deduct 1638 from 2140 and we're left with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

The final result is 15037.42612942 with a remainder of 5.02e-07.
