We divide 54288753 by 135
We want to divide 54288753 by 135.

Step 1:
The number 135 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 135

Going ahead to step 2:
135 can be fit into 54 0 times, resulting in a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 135

Moving on to step 3:
135 can be fit into 542 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 2 after subtracting 540 from 542.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 135

Going ahead to step 4:
The number 135 fits into 28 0 times, leaving a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we take 0 away from 28, we end up with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 135

Going ahead to step 5:
288 divided by 135 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 402.0
Subtract 270 from 288 to get 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 135

Step 6:
187 divided by 135 is 1 with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 4021.0
If we subtract 135 from 187, we get 52.
Grab the next digit (5) from the dividend, add it to 52, then carry on: 525 / 135

Step 7:
If we divide 525 by 135, we get 3 and a remainder of 120.
Record the quotient 3 as the next digit in the result. 
Result so far: 40213.0
Deduct 405 from 525 and we're left with 120.
Append the next digit (3) from the dividend to 120 and continue with: 1203 / 135

On to step 8:
If we divide 1203 by 135, we get 8 and a remainder of 123.
Write down 8 as next digit of the result. 
Result so far: 402138.0
Deduct 1080 from 1203 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 9:
135 can be fit into 1230 9 times, resulting in a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 402138.9
Deduct 1215 from 1230 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
The number 135 fits into 150 1 times, leaving a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 402138.91
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
150 divided by 135 is 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 402138.911
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 402138.911, with a leftover of 0.0015.
