Let's divide 54872851 by 415
We want to divide 54872851 by 415.

Advancing to step 1:
415 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 415

Advancing to step 2:
415 goes into 54 0 times with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Include the next digit (8) from the dividend after 54, then repeat: 548 / 415

Step 3:
If we divide 548 by 415, we get 1 and a remainder of 133.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 415 from 548 leaves us with 133.
Bring next digit (7) of the dividend behind the 133 and repeat the process: 1337 / 415

Step 4:
415 goes into 1337 3 times with a remainder of 92.
The next digit of our result is 3. 
Result so far: 13.0
If we take 1245 away from 1337, we end up with 92.
Append the next digit (2) from the dividend to 92 and continue with: 922 / 415

Going ahead to step 5:
415 goes into 922 2 times with a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 132.0
Subtract 830 from 922 to get 92.
Fetch the next digit (8) from the dividend, attach it to 92 and continue: 928 / 415

Advancing to step 6:
415 can be fit into 928 2 times, resulting in a remainder of 98.
Record the quotient 2 as the next digit in the result. 
Result so far: 1322.0
Deduct 830 from 928 and we're left with 98.
Append the next digit (5) from the dividend to 98 and continue with: 985 / 415

Step 7:
If we divide 985 by 415, we get 2 and a remainder of 155.
Put 2 as the next digit of the answer. 
Result so far: 13222.0
Subtracting 830 from 985 leaves us with 155.
Include the next digit (1) from the dividend after 155, then repeat: 1551 / 415

Step 8:
If we divide 1551 by 415, we get 3 and a remainder of 306.
Record the quotient 3 as the next digit in the result. 
Result so far: 132223.0
If we subtract 1245 from 1551, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 9:
When dividing 3060 by 415, we get 7 with a remainder of 155.
Put 7 as the next digit of the answer. 
Result so far: 132223.7
Subtracting 2905 from 3060 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 10:
If we divide 1550 by 415, we get 3 and a remainder of 305.
Use 3 as the next digit of our solution. 
Result so far: 132223.73
Subtracting 1245 from 1550 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 11:
3050 divided by 415 is 7 with a remainder of 145.
Use 7 as the next digit of our solution. 
Result so far: 132223.737
If we take 2905 away from 3050, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 12:
415 goes into 1450 3 times with a remainder of 205.
Record the quotient 3 as the next digit in the result. 
Result so far: 132223.7373
If we subtract 1245 from 1450, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 13:
415 goes into 2050 4 times with a remainder of 390.
The next digit of our result is 4. 
Result so far: 132223.73734
The remainder is 390 after subtracting 1660 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 14:
When dividing 3900 by 415, we get 9 with a remainder of 165.
Use 9 as the next digit of our solution. 
Result so far: 132223.737349
Deduct 3735 from 3900 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 15:
When dividing 1650 by 415, we get 3 with a remainder of 405.
The number 3 becomes the next digit in our result. 
Result so far: 132223.7373493
The remainder is 405 after subtracting 1245 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 16:
4050 divided by 415 is 9 with a remainder of 315.
Put 9 as the next digit of the answer. 
Result so far: 132223.73734939
The remainder is 315 after subtracting 3735 from 4050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The final result is 132223.73734939 with a remainder of 3.15e-07.
