54777232 ÷ 387 
Our goal is to divide 54777232 by 387.

Advancing to step 1:
The number 387 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 387

Advancing to step 2:
The number 387 fits into 54 0 times, leaving a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Bring next digit (7) of the dividend behind the 54 and repeat the process: 547 / 387

Moving on to step 3:
387 goes into 547 1 times with a remainder of 160.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 387 away from 547, we end up with 160.
Append the next digit (7) from the dividend to 160 and continue with: 1607 / 387

Going ahead to step 4:
387 goes into 1607 4 times with a remainder of 59.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 1548 from 1607 to get 59.
Fetch the next digit (7) from the dividend, attach it to 59 and continue: 597 / 387

Let's proceed to step 5:
When dividing 597 by 387, we get 1 with a remainder of 210.
Use 1 as the next digit of our solution. 
Result so far: 141.0
Subtracting 387 from 597 leaves us with 210.
Take the next digit (2) from the dividend and append it to 210, then repeat: 2102 / 387

Going ahead to step 6:
2102 divided by 387 is 5 with a remainder of 167.
Write down 5 as next digit of the result. 
Result so far: 1415.0
If we take 1935 away from 2102, we end up with 167.
Include the next digit (3) from the dividend after 167, then repeat: 1673 / 387

On to step 7:
If we divide 1673 by 387, we get 4 and a remainder of 125.
Put 4 as the next digit of the answer. 
Result so far: 14154.0
The remainder is 125 after subtracting 1548 from 1673.
Bring next digit (2) of the dividend behind the 125 and repeat the process: 1252 / 387

Step 8:
387 goes into 1252 3 times with a remainder of 91.
The number 3 becomes the next digit in our result. 
Result so far: 141543.0
The remainder is 91 after subtracting 1161 from 1252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 9:
The number 387 fits into 910 2 times, leaving a remainder of 136.
Use 2 as the next digit of our solution. 
Result so far: 141543.2
If we take 774 away from 910, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 10:
The number 387 fits into 1360 3 times, leaving a remainder of 199.
Put 3 as the next digit of the answer. 
Result so far: 141543.23
The remainder is 199 after subtracting 1161 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Advancing to step 11:
387 can be fit into 1990 5 times, resulting in a remainder of 55.
The next digit of our result is 5. 
Result so far: 141543.235
If we subtract 1935 from 1990, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 12:
387 can be fit into 550 1 times, resulting in a remainder of 163.
Write down 1 as next digit of the result. 
Result so far: 141543.2351
Subtracting 387 from 550 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 13:
387 can be fit into 1630 4 times, resulting in a remainder of 82.
The number 4 becomes the next digit in our result. 
Result so far: 141543.23514
If we subtract 1548 from 1630, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 14:
If we divide 820 by 387, we get 2 and a remainder of 46.
The next digit of our result is 2. 
Result so far: 141543.235142
Subtract 774 from 820 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 15:
The number 387 fits into 460 1 times, leaving a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 141543.2351421
If we subtract 387 from 460, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 16:
730 divided by 387 is 1 with a remainder of 343.
Write down 1 as next digit of the result. 
Result so far: 141543.23514211
If we subtract 387 from 730, we get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

The final outcome is 141543.23514211, with a leftover of 3.43e-07.
