Let's divide 54578192 by 138
We want to divide 54578192 by 138.

Moving on to step 1:
5 divided by 138 is 0 with 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.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 138

Step 2:
If we divide 54 by 138, we get 0 and a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 138

Moving on to step 3:
The number 138 fits into 545 3 times, leaving a remainder of 131.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 414 away from 545, we end up with 131.
Fetch the next digit (7) from the dividend, attach it to 131 and continue: 1317 / 138

Step 4:
The number 138 fits into 1317 9 times, leaving a remainder of 75.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 1242 from 1317 to get 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 138

Advancing to step 5:
If we divide 758 by 138, we get 5 and a remainder of 68.
The next digit of our result is 5. 
Result so far: 395.0
Subtract 690 from 758 to get 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 138

Moving on to step 6:
138 goes into 681 4 times with a remainder of 129.
The number 4 becomes the next digit in our result. 
Result so far: 3954.0
The remainder is 129 after subtracting 552 from 681.
Include the next digit (9) from the dividend after 129, then repeat: 1299 / 138

Step 7:
When dividing 1299 by 138, we get 9 with a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 39549.0
Subtract 1242 from 1299 to get 57.
Fetch the next digit (2) from the dividend, attach it to 57 and continue: 572 / 138

Going ahead to step 8:
572 divided by 138 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 395494.0
Deduct 552 from 572 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
If we divide 200 by 138, we get 1 and a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 395494.1
Subtracting 138 from 200 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 10:
If we divide 620 by 138, we get 4 and a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 395494.14
If we take 552 away from 620, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 11:
When dividing 680 by 138, we get 4 with a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 395494.144
If we subtract 552 from 680, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 395494.144, with a leftover of 0.0128.
