48120177 ÷ 903 
We want to divide 48120177 by 903.

Moving on to step 1:
903 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 903

Let's proceed to step 2:
The number 903 fits into 48 0 times, leaving a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 903

Going ahead to step 3:
481 divided by 903 is 0 with a remainder of 481.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 481 to get 481.
Include the next digit (2) from the dividend after 481, then repeat: 4812 / 903

Step 4:
The number 903 fits into 4812 5 times, leaving a remainder of 297.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 297 after subtracting 4515 from 4812.
Include the next digit (0) from the dividend after 297, then repeat: 2970 / 903

On to step 5:
When dividing 2970 by 903, we get 3 with a remainder of 261.
The next digit of our result is 3. 
Result so far: 53.0
The remainder is 261 after subtracting 2709 from 2970.
Fetch the next digit (1) from the dividend, attach it to 261 and continue: 2611 / 903

On to step 6:
When dividing 2611 by 903, we get 2 with a remainder of 805.
Record the quotient 2 as the next digit in the result. 
Result so far: 532.0
If we subtract 1806 from 2611, we get 805.
Append the next digit (7) from the dividend to 805 and continue with: 8057 / 903

Moving on to step 7:
903 goes into 8057 8 times with a remainder of 833.
The number 8 becomes the next digit in our result. 
Result so far: 5328.0
The remainder is 833 after subtracting 7224 from 8057.
Grab the next digit (7) from the dividend, add it to 833, then carry on: 8337 / 903

Going ahead to step 8:
The number 903 fits into 8337 9 times, leaving a remainder of 210.
Put 9 as the next digit of the answer. 
Result so far: 53289.0
Deduct 8127 from 8337 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 9:
903 can be fit into 2100 2 times, resulting in a remainder of 294.
Use 2 as the next digit of our solution. 
Result so far: 53289.2
The remainder is 294 after subtracting 1806 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 10:
2940 divided by 903 is 3 with a remainder of 231.
Record the quotient 3 as the next digit in the result. 
Result so far: 53289.23
Subtract 2709 from 2940 to get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Step 11:
903 can be fit into 2310 2 times, resulting in a remainder of 504.
Put 2 as the next digit of the answer. 
Result so far: 53289.232
Subtract 1806 from 2310 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Step 12:
903 can be fit into 5040 5 times, resulting in a remainder of 525.
Write down 5 as next digit of the result. 
Result so far: 53289.2325
Deduct 4515 from 5040 and we're left with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Step 13:
903 can be fit into 5250 5 times, resulting in a remainder of 735.
The number 5 becomes the next digit in our result. 
Result so far: 53289.23255
The remainder is 735 after subtracting 4515 from 5250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

The final result is 53289.23255 with a remainder of 0.000735.
