15995544 ÷ 412 
We want to figure out the number of times 15995544 can be divided by 412.

On to step 1:
If we divide 1 by 412, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 412

Let's proceed to step 2:
15 divided by 412 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 412

On to step 3:
If we divide 159 by 412, we get 0 and a remainder of 159.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 159 to get 159.
Grab the next digit (9) from the dividend, add it to 159, then carry on: 1599 / 412

Going ahead to step 4:
The number 412 fits into 1599 3 times, leaving a remainder of 363.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1236 away from 1599, we end up with 363.
Take the next digit (5) from the dividend and append it to 363, then repeat: 3635 / 412

On to step 5:
When dividing 3635 by 412, we get 8 with a remainder of 339.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtracting 3296 from 3635 leaves us with 339.
Include the next digit (5) from the dividend after 339, then repeat: 3395 / 412

Going ahead to step 6:
412 can be fit into 3395 8 times, resulting in a remainder of 99.
Use 8 as the next digit of our solution. 
Result so far: 388.0
Subtracting 3296 from 3395 leaves us with 99.
Include the next digit (4) from the dividend after 99, then repeat: 994 / 412

Going ahead to step 7:
412 can be fit into 994 2 times, resulting in a remainder of 170.
Put 2 as the next digit of the answer. 
Result so far: 3882.0
Subtract 824 from 994 to get 170.
Bring next digit (4) of the dividend behind the 170 and repeat the process: 1704 / 412

On to step 8:
1704 divided by 412 is 4 with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 38824.0
Subtract 1648 from 1704 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
The number 412 fits into 560 1 times, leaving a remainder of 148.
Use 1 as the next digit of our solution. 
Result so far: 38824.1
Deduct 412 from 560 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 10:
If we divide 1480 by 412, we get 3 and a remainder of 244.
Record the quotient 3 as the next digit in the result. 
Result so far: 38824.13
Deduct 1236 from 1480 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 11:
When dividing 2440 by 412, we get 5 with a remainder of 380.
Put 5 as the next digit of the answer. 
Result so far: 38824.135
Subtract 2060 from 2440 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 12:
When dividing 3800 by 412, we get 9 with a remainder of 92.
Put 9 as the next digit of the answer. 
Result so far: 38824.1359
Subtracting 3708 from 3800 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 13:
920 divided by 412 is 2 with a remainder of 96.
The next digit of our result is 2. 
Result so far: 38824.13592
Subtracting 824 from 920 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 14:
412 can be fit into 960 2 times, resulting in a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 38824.135922
Deduct 824 from 960 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final result is 38824.135922 with a remainder of 1.36e-05.
