54312419 divided by 136 
Our goal is to divide 54312419 by 136.

Moving on to step 1:
When dividing 5 by 136, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 136

Let's proceed to step 2:
136 goes into 54 0 times with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Fetch the next digit (3) from the dividend, attach it to 54 and continue: 543 / 136

Advancing to step 3:
If we divide 543 by 136, we get 3 and a remainder of 135.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 408 away from 543, we end up with 135.
Fetch the next digit (1) from the dividend, attach it to 135 and continue: 1351 / 136

Step 4:
If we divide 1351 by 136, we get 9 and a remainder of 127.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtract 1224 from 1351 to get 127.
Include the next digit (2) from the dividend after 127, then repeat: 1272 / 136

Moving on to step 5:
The number 136 fits into 1272 9 times, leaving a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 399.0
Subtracting 1224 from 1272 leaves us with 48.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 136

Moving on to step 6:
The number 136 fits into 484 3 times, leaving a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 3993.0
Deduct 408 from 484 and we're left with 76.
Fetch the next digit (1) from the dividend, attach it to 76 and continue: 761 / 136

Going ahead to step 7:
136 goes into 761 5 times with a remainder of 81.
The number 5 becomes the next digit in our result. 
Result so far: 39935.0
If we subtract 680 from 761, we get 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 136

Advancing to step 8:
819 divided by 136 is 6 with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 399356.0
If we subtract 816 from 819, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
136 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 399356.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
136 can be fit into 300 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 399356.02
If we take 272 away from 300, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
280 divided by 136 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 399356.022
Subtract 272 from 280 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.

In conclusion, the division gives 399356.022 with a balance of 0.0008.
