55481015 ÷ 381 
We want to figure out the number of times 55481015 can be divided by 381.

Advancing to step 1:
When dividing 5 by 381, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 381

Step 2:
381 can be fit into 55 0 times, resulting in a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 381

Going ahead to step 3:
381 goes into 554 1 times with a remainder of 173.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 173 after subtracting 381 from 554.
Include the next digit (8) from the dividend after 173, then repeat: 1738 / 381

Let's proceed to step 4:
381 goes into 1738 4 times with a remainder of 214.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 1524 from 1738 to get 214.
Include the next digit (1) from the dividend after 214, then repeat: 2141 / 381

Moving on to step 5:
If we divide 2141 by 381, we get 5 and a remainder of 236.
The number 5 becomes the next digit in our result. 
Result so far: 145.0
Subtract 1905 from 2141 to get 236.
Bring next digit (0) of the dividend behind the 236 and repeat the process: 2360 / 381

Going ahead to step 6:
2360 divided by 381 is 6 with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 1456.0
If we subtract 2286 from 2360, we get 74.
Append the next digit (1) from the dividend to 74 and continue with: 741 / 381

Let's proceed to step 7:
If we divide 741 by 381, we get 1 and a remainder of 360.
The next digit of our result is 1. 
Result so far: 14561.0
If we take 381 away from 741, we end up with 360.
Take the next digit (5) from the dividend and append it to 360, then repeat: 3605 / 381

Moving on to step 8:
381 goes into 3605 9 times with a remainder of 176.
The next digit of our result is 9. 
Result so far: 145619.0
If we take 3429 away from 3605, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 9:
When dividing 1760 by 381, we get 4 with a remainder of 236.
Record the quotient 4 as the next digit in the result. 
Result so far: 145619.4
Subtracting 1524 from 1760 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 10:
381 can be fit into 2360 6 times, resulting in a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 145619.46
If we subtract 2286 from 2360, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 11:
When dividing 740 by 381, we get 1 with a remainder of 359.
Record the quotient 1 as the next digit in the result. 
Result so far: 145619.461
The remainder is 359 after subtracting 381 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Moving on to step 12:
The number 381 fits into 3590 9 times, leaving a remainder of 161.
The number 9 becomes the next digit in our result. 
Result so far: 145619.4619
The remainder is 161 after subtracting 3429 from 3590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Advancing to step 13:
1610 divided by 381 is 4 with a remainder of 86.
Use 4 as the next digit of our solution. 
Result so far: 145619.46194
Subtract 1524 from 1610 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 14:
If we divide 860 by 381, we get 2 and a remainder of 98.
Put 2 as the next digit of the answer. 
Result so far: 145619.461942
If we take 762 away from 860, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 15:
If we divide 980 by 381, we get 2 and a remainder of 218.
The number 2 becomes the next digit in our result. 
Result so far: 145619.4619422
Deduct 762 from 980 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

The final result is 145619.4619422 with a remainder of 2.18e-06.
