Let's divide 121904 by 16
We're looking to find how many times 16 goes into 121904.

Let's proceed to step 1:
16 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 (2) from the dividend, add it to 1, then carry on: 12 / 16

Moving on to step 2:
When dividing 12 by 16, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 16

Going ahead to step 3:
The number 16 fits into 121 7 times, leaving a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 112 from 121 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 16

Moving on to step 4:
99 divided by 16 is 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
The remainder is 3 after subtracting 96 from 99.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 16

On to step 5:
The number 16 fits into 30 1 times, leaving a remainder of 14.
The next digit of our result is 1. 
Result so far: 761.0
Deduct 16 from 30 and we're left with 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 16

Step 6:
16 can be fit into 144 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 7619.0
If we subtract 144 from 144, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
16 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7619.0
If we take 0 away from 0, 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.

Moving on to step 8:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7619.0
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.

Our division results in 7619.0 with a remaining 0.0.
