We're dividing 54391088 by 381 
We want to figure out the number of times 54391088 can be divided by 381.

Advancing to step 1:
The number 381 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 381

Advancing to step 2:
If we divide 54 by 381, we get 0 and a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 381

Advancing to step 3:
When dividing 543 by 381, we get 1 with a remainder of 162.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 381 from 543 to get 162.
Include the next digit (9) from the dividend after 162, then repeat: 1629 / 381

Let's proceed to step 4:
If we divide 1629 by 381, we get 4 and a remainder of 105.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 1524 away from 1629, we end up with 105.
Grab the next digit (1) from the dividend, add it to 105, then carry on: 1051 / 381

Moving on to step 5:
If we divide 1051 by 381, we get 2 and a remainder of 289.
Write down 2 as next digit of the result. 
Result so far: 142.0
If we subtract 762 from 1051, we get 289.
Bring next digit (0) of the dividend behind the 289 and repeat the process: 2890 / 381

Moving on to step 6:
When dividing 2890 by 381, we get 7 with a remainder of 223.
Write down 7 as next digit of the result. 
Result so far: 1427.0
If we take 2667 away from 2890, we end up with 223.
Bring next digit (8) of the dividend behind the 223 and repeat the process: 2238 / 381

Moving on to step 7:
381 goes into 2238 5 times with a remainder of 333.
The next digit of our result is 5. 
Result so far: 14275.0
The remainder is 333 after subtracting 1905 from 2238.
Append the next digit (8) from the dividend to 333 and continue with: 3338 / 381

Moving on to step 8:
If we divide 3338 by 381, we get 8 and a remainder of 290.
Use 8 as the next digit of our solution. 
Result so far: 142758.0
Subtract 3048 from 3338 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 9:
The number 381 fits into 2900 7 times, leaving a remainder of 233.
Record the quotient 7 as the next digit in the result. 
Result so far: 142758.7
Deduct 2667 from 2900 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Going ahead to step 10:
The number 381 fits into 2330 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 142758.76
If we subtract 2286 from 2330, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
381 goes into 440 1 times with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 142758.761
Subtract 381 from 440 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 12:
381 can be fit into 590 1 times, resulting in a remainder of 209.
Put 1 as the next digit of the answer. 
Result so far: 142758.7611
If we subtract 381 from 590, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

The quotient of the division is 142758.7611, and the remainder is 0.00209.
