54546394 ÷ 128 
We're looking to find how many times 128 goes into 54546394.

Moving on to step 1:
When dividing 5 by 128, we get 0 with 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 (4) from the dividend to 5 and continue with: 54 / 128

Let's proceed to step 2:
The number 128 fits into 54 0 times, leaving a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Fetch the next digit (5) from the dividend, attach it to 54 and continue: 545 / 128

Advancing to step 3:
The number 128 fits into 545 4 times, leaving a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 512 from 545 and we're left with 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 128

Moving on to step 4:
128 goes into 334 2 times with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 78 after subtracting 256 from 334.
Take the next digit (6) from the dividend and append it to 78, then repeat: 786 / 128

Step 5:
When dividing 786 by 128, we get 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 426.0
The remainder is 18 after subtracting 768 from 786.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 128

Advancing to step 6:
128 goes into 183 1 times with a remainder of 55.
The next digit of our result is 1. 
Result so far: 4261.0
Deduct 128 from 183 and we're left with 55.
Take the next digit (9) from the dividend and append it to 55, then repeat: 559 / 128

On to step 7:
128 can be fit into 559 4 times, resulting in a remainder of 47.
The next digit of our result is 4. 
Result so far: 42614.0
The remainder is 47 after subtracting 512 from 559.
Bring next digit (4) of the dividend behind the 47 and repeat the process: 474 / 128

Let's proceed to step 8:
If we divide 474 by 128, we get 3 and a remainder of 90.
Write down 3 as next digit of the result. 
Result so far: 426143.0
If we take 384 away from 474, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 9:
128 can be fit into 900 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 426143.7
Subtracting 896 from 900 leaves us 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.

Step 10:
The number 128 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 426143.7
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
If we divide 400 by 128, we get 3 and a remainder of 16.
The next digit of our result is 3. 
Result so far: 426143.703
If we subtract 384 from 400, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
When dividing 160 by 128, we get 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 426143.7031
If we subtract 128 from 160, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
The number 128 fits into 320 2 times, leaving a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 426143.70312
The remainder is 64 after subtracting 256 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 14:
When dividing 640 by 128, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 426143.703125
The remainder is 0 after subtracting 640 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 15:
128 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 426143.703125
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.

Step 16:
128 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 426143.703125
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 426143.703125, and the remainder is 0.0.
