We look at the division of 120990 by 16 
We want to figure out the number of times 120990 can be divided by 16.

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

On to step 2:
16 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 16

Advancing to step 3:
120 divided by 16 is 7 with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 112 from 120 leaves us with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 16

Going ahead to step 4:
If we divide 89 by 16, we get 5 and a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
If we take 80 away from 89, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 16

Let's proceed to step 5:
99 divided by 16 is 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 756.0
If we take 96 away from 99, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 16

Going ahead to step 6:
16 can be fit into 30 1 times, resulting in a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 7561.0
If we subtract 16 from 30, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
140 divided by 16 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 7561.8
The remainder is 12 after subtracting 128 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
When dividing 120 by 16, we get 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 7561.87
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
If we divide 80 by 16, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 7561.875
If we subtract 80 from 80, 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.

Advancing to step 10:
If we divide 0 by 16, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 7561.875
Subtract 0 from 0 to 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.

On to step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7561.875
If we subtract 0 from 0, 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.

The quotient of the division is 7561.875, and the remainder is 0.0.
