45545450 ÷ 54 
We want to figure out the number of times 45545450 can be divided by 54.

Advancing to step 1:
When dividing 4 by 54, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 54

Step 2:
54 goes into 45 0 times with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 54

Going ahead to step 3:
54 goes into 455 8 times with a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 432 from 455 to get 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 54

Moving on to step 4:
54 can be fit into 234 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Subtract 216 from 234 to get 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 54

On to step 5:
The number 54 fits into 185 3 times, leaving a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 843.0
The remainder is 23 after subtracting 162 from 185.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 54

Step 6:
When dividing 234 by 54, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 8434.0
If we subtract 216 from 234, we get 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 54

Moving on to step 7:
54 can be fit into 185 3 times, resulting in a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 84343.0
Subtracting 162 from 185 leaves us with 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 54

Moving on to step 8:
If we divide 230 by 54, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 843434.0
Subtracting 216 from 230 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
If we divide 140 by 54, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 843434.2
If we subtract 108 from 140, 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.

Going ahead to step 10:
If we divide 320 by 54, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 843434.25
Deduct 270 from 320 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
If we divide 500 by 54, we get 9 and a remainder of 14.
The next digit of our result is 9. 
Result so far: 843434.259
If we take 486 away from 500, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
When dividing 140 by 54, we get 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 843434.2592
If we take 108 away from 140, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
The number 54 fits into 320 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 843434.25925
Subtracting 270 from 320 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
54 can be fit into 500 9 times, resulting in a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 843434.259259
Subtracting 486 from 500 leaves us with 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 15:
When dividing 140 by 54, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 843434.2592592
Deduct 108 from 140 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 16:
When dividing 320 by 54, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 843434.25925925
If we take 270 away from 320, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 843434.25925925 with a remaining 5e-08.
