We look at the division of 53996420 by 16 
We're looking to find how many times 16 goes into 53996420.

Advancing to step 1:
16 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 16

Advancing to step 2:
When dividing 53 by 16, we get 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 48 from 53 to get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 16

Let's proceed to step 3:
If we divide 59 by 16, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 33.0
Deduct 48 from 59 and we're left with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 16

Going ahead to step 4:
The number 16 fits into 119 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 337.0
Deduct 112 from 119 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 16

Moving on to step 5:
16 can be fit into 76 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 3374.0
Deduct 64 from 76 and we're left with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 16

Step 6:
If we divide 124 by 16, we get 7 and a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 33747.0
Deduct 112 from 124 and we're left with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 16

On to step 7:
When dividing 122 by 16, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 337477.0
If we take 112 away from 122, we end up with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 16

Moving on to step 8:
16 goes into 100 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 3374776.0
If we take 96 away from 100, 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.

Moving on to step 9:
40 divided by 16 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 3374776.2
If we subtract 32 from 40, 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.

Step 10:
If we divide 80 by 16, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 3374776.25
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.

Going ahead to step 11:
0 divided by 16 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3374776.25
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.

On to step 12:
If we divide 0 by 16, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3374776.25
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 final outcome is 3374776.25, with a leftover of 0.0.
