54396063 divided by 331 
Our goal is to divide 54396063 by 331.

Let's proceed to step 1:
When dividing 5 by 331, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 331

Let's proceed to step 2:
If we divide 54 by 331, we get 0 and a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Fetch the next digit (3) from the dividend, attach it to 54 and continue: 543 / 331

Advancing to step 3:
The number 331 fits into 543 1 times, leaving a remainder of 212.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 331 from 543 and we're left with 212.
Take the next digit (9) from the dividend and append it to 212, then repeat: 2129 / 331

Let's proceed to step 4:
331 can be fit into 2129 6 times, resulting in a remainder of 143.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 1986 from 2129 leaves us with 143.
Fetch the next digit (6) from the dividend, attach it to 143 and continue: 1436 / 331

Let's proceed to step 5:
When dividing 1436 by 331, we get 4 with a remainder of 112.
Write down 4 as next digit of the result. 
Result so far: 164.0
If we subtract 1324 from 1436, we get 112.
Bring next digit (0) of the dividend behind the 112 and repeat the process: 1120 / 331

Advancing to step 6:
When dividing 1120 by 331, we get 3 with a remainder of 127.
Use 3 as the next digit of our solution. 
Result so far: 1643.0
The remainder is 127 after subtracting 993 from 1120.
Fetch the next digit (6) from the dividend, attach it to 127 and continue: 1276 / 331

On to step 7:
1276 divided by 331 is 3 with a remainder of 283.
The next digit of our result is 3. 
Result so far: 16433.0
The remainder is 283 after subtracting 993 from 1276.
Fetch the next digit (3) from the dividend, attach it to 283 and continue: 2833 / 331

Step 8:
331 can be fit into 2833 8 times, resulting in a remainder of 185.
The next digit of our result is 8. 
Result so far: 164338.0
Deduct 2648 from 2833 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 9:
331 goes into 1850 5 times with a remainder of 195.
Record the quotient 5 as the next digit in the result. 
Result so far: 164338.5
The remainder is 195 after subtracting 1655 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 10:
331 can be fit into 1950 5 times, resulting in a remainder of 295.
The number 5 becomes the next digit in our result. 
Result so far: 164338.55
Subtract 1655 from 1950 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

The quotient of the division is 164338.55, and the remainder is 0.295.
