We look at the division of 181689 by 16 
We want to divide 181689 by 16.

Moving on to step 1:
The number 16 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 16

Advancing to step 2:
16 goes into 18 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 16 from 18, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 16

Advancing to step 3:
If we divide 21 by 16, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 16 from 21 to get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 16

Moving on to step 4:
The number 16 fits into 56 3 times, leaving a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 113.0
The remainder is 8 after subtracting 48 from 56.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 16

Advancing to step 5:
When dividing 88 by 16, we get 5 with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 1135.0
Subtracting 80 from 88 leaves us with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 16

Advancing to step 6:
If we divide 89 by 16, we get 5 and a remainder of 9.
The next digit of our result is 5. 
Result so far: 11355.0
Subtract 80 from 89 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
If we divide 90 by 16, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 11355.5
Subtracting 80 from 90 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
16 can be fit into 100 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 11355.56
Deduct 96 from 100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
16 goes into 40 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 11355.562
Deduct 32 from 40 and we're left 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.

Step 10:
16 goes into 80 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 11355.5625
If we take 80 away from 80, we end up 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.

Advancing to step 11:
0 divided by 16 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11355.5625
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.

On to step 12:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11355.5625
Subtracting 0 from 0 leaves us 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.

The final result is 11355.5625 with a remainder of 0.0.
