139549 divided by 16 
Our goal is to divide 139549 by 16.

Let's proceed to step 1:
16 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 16

Advancing to step 2:
13 divided by 16 is 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 16

Step 3:
16 can be fit into 139 8 times, resulting in a remainder of 11.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 128 from 139 leaves us with 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 16

Going ahead to step 4:
When dividing 115 by 16, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Deduct 112 from 115 and we're left with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 16

Let's proceed to step 5:
34 divided by 16 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 872.0
Subtracting 32 from 34 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 16

Step 6:
When dividing 29 by 16, we get 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 8721.0
Deduct 16 from 29 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
The number 16 fits into 130 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8721.8
Deduct 128 from 130 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
When dividing 20 by 16, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 8721.81
The remainder is 4 after subtracting 16 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
The number 16 fits into 40 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 8721.812
If we take 32 away from 40, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
16 can be fit into 80 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8721.8125
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8721.8125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8721.8125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 8721.8125 and a remainder of 0.0.
