54512136 ÷ 16 
Our goal is to divide 54512136 by 16.

Let's proceed 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
If we take 0 away from 5, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 16

Going ahead to step 2:
16 can be fit into 54 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 48 from 54, we get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 16

Step 3:
The number 16 fits into 65 4 times, leaving a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Deduct 64 from 65 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 16

Step 4:
16 goes into 11 0 times with a remainder of 11.
The next digit of our result is 0. 
Result so far: 340.0
Deduct 0 from 11 and we're left with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 16

On to step 5:
The number 16 fits into 112 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 3407.0
If we take 112 away from 112, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 16

Let's proceed to step 6:
1 divided by 16 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 34070.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 16

Going ahead to step 7:
16 goes into 13 0 times with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 340700.0
If we subtract 0 from 13, we get 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 16

Going ahead to step 8:
If we divide 136 by 16, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 3407008.0
Subtract 128 from 136 to 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.

Advancing to step 9:
If we divide 80 by 16, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3407008.5
Subtracting 80 from 80 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.

Going ahead to step 10:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3407008.5
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.

Going ahead to step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3407008.5
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 outcome is 3407008.5, with a leftover of 0.0.
