We look at the division of 15942449 by 105 
Our goal is to divide 15942449 by 105.

Let's proceed to step 1:
105 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 105

On to step 2:
The number 105 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 105

Moving on to step 3:
159 divided by 105 is 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 105 from 159 and we're left with 54.
Fetch the next digit (4) from the dividend, attach it to 54 and continue: 544 / 105

Let's proceed to step 4:
544 divided by 105 is 5 with a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 525 from 544 and we're left with 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 105

On to step 5:
If we divide 192 by 105, we get 1 and a remainder of 87.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
If we subtract 105 from 192, we get 87.
Append the next digit (4) from the dividend to 87 and continue with: 874 / 105

Moving on to step 6:
105 can be fit into 874 8 times, resulting in a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 1518.0
If we take 840 away from 874, we end up with 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 105

Step 7:
105 can be fit into 344 3 times, resulting in a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 15183.0
Deduct 315 from 344 and we're left with 29.
Take the next digit (9) from the dividend and append it to 29, then repeat: 299 / 105

On to step 8:
If we divide 299 by 105, we get 2 and a remainder of 89.
Use 2 as the next digit of our solution. 
Result so far: 151832.0
If we take 210 away from 299, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 9:
If we divide 890 by 105, we get 8 and a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 151832.8
If we subtract 840 from 890, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
105 goes into 500 4 times with a remainder of 80.
The next digit of our result is 4. 
Result so far: 151832.84
Subtracting 420 from 500 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
The number 105 fits into 800 7 times, leaving a remainder of 65.
The next digit of our result is 7. 
Result so far: 151832.847
The remainder is 65 after subtracting 735 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 12:
105 goes into 650 6 times with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 151832.8476
Subtract 630 from 650 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
200 divided by 105 is 1 with a remainder of 95.
Use 1 as the next digit of our solution. 
Result so far: 151832.84761
Subtracting 105 from 200 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 14:
105 can be fit into 950 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 151832.847619
If we take 945 away from 950, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 15:
105 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 151832.847619
If we take 0 away from 50, we end up 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 16:
105 can be fit into 500 4 times, resulting in a remainder of 80.
The next digit of our result is 4. 
Result so far: 151832.84761904
If we take 420 away from 500, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 151832.84761904, and the remainder is 8e-08.
