We're dividing 54435642 by 75 
Our goal is to divide 54435642 by 75.

On to step 1:
The number 75 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 75

Going ahead to step 2:
75 can be fit into 54 0 times, resulting in a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Take the next digit (4) from the dividend and append it to 54, then repeat: 544 / 75

On to step 3:
544 divided by 75 is 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 525 from 544 and we're left with 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 75

On to step 4:
75 can be fit into 193 2 times, resulting in a remainder of 43.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Subtract 150 from 193 to get 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 75

Moving on to step 5:
75 goes into 435 5 times with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 725.0
The remainder is 60 after subtracting 375 from 435.
Append the next digit (6) from the dividend to 60 and continue with: 606 / 75

Let's proceed to step 6:
75 goes into 606 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 7258.0
Subtracting 600 from 606 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 75

On to step 7:
64 divided by 75 is 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 72580.0
If we subtract 0 from 64, we get 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 75

Step 8:
The number 75 fits into 642 8 times, leaving a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 725808.0
Deduct 600 from 642 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
The number 75 fits into 420 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 725808.5
Deduct 375 from 420 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
When dividing 450 by 75, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 725808.56
Subtract 450 from 450 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.

Moving on to step 11:
75 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 725808.56
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:
If we divide 0 by 75, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 725808.56
If we take 0 away from 0, we end up 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.

Our division results in 725808.56 with a remaining 0.0.
