We're dividing 120621 by 16 
We want to figure out the number of times 120621 can be divided by 16.

Moving on to step 1:
The number 16 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 16

Let's proceed to step 2:
If we divide 12 by 16, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 16

Advancing to step 3:
120 divided by 16 is 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 8 after subtracting 112 from 120.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 16

Moving on to step 4:
16 goes into 86 5 times with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Subtracting 80 from 86 leaves us with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 16

Step 5:
16 goes into 62 3 times with a remainder of 14.
The next digit of our result is 3. 
Result so far: 753.0
If we subtract 48 from 62, we get 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 16

Moving on to step 6:
141 divided by 16 is 8 with a remainder of 13.
The next digit of our result is 8. 
Result so far: 7538.0
If we subtract 128 from 141, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
16 can be fit into 130 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 7538.8
Subtract 128 from 130 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
16 can be fit into 20 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 7538.81
If we take 16 away from 20, we end up 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:
If we divide 40 by 16, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 7538.812
Subtracting 32 from 40 leaves us 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.

Let's proceed to step 10:
80 divided by 16 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7538.8125
Deduct 80 from 80 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.

Advancing to step 11:
If we divide 0 by 16, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7538.8125
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.

Advancing 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: 7538.8125
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.

The quotient of the division is 7538.8125, and the remainder is 0.0.
