We divide 53155278 by 415
Let's see how many times 415 fits into 53155278.

On 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
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 415

Going ahead to step 2:
53 divided by 415 is 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 415

Step 3:
When dividing 531 by 415, we get 1 with a remainder of 116.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 415 from 531 leaves us with 116.
Bring next digit (5) of the dividend behind the 116 and repeat the process: 1165 / 415

Going ahead to step 4:
415 goes into 1165 2 times with a remainder of 335.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 830 from 1165, we get 335.
Include the next digit (5) from the dividend after 335, then repeat: 3355 / 415

Advancing to step 5:
The number 415 fits into 3355 8 times, leaving a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Deduct 3320 from 3355 and we're left with 35.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 415

Going ahead to step 6:
When dividing 352 by 415, we get 0 with a remainder of 352.
The number 0 becomes the next digit in our result. 
Result so far: 1280.0
If we subtract 0 from 352, we get 352.
Fetch the next digit (7) from the dividend, attach it to 352 and continue: 3527 / 415

Going ahead to step 7:
415 can be fit into 3527 8 times, resulting in a remainder of 207.
Use 8 as the next digit of our solution. 
Result so far: 12808.0
Subtract 3320 from 3527 to get 207.
Take the next digit (8) from the dividend and append it to 207, then repeat: 2078 / 415

On to step 8:
415 can be fit into 2078 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 128085.0
Subtracting 2075 from 2078 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
If we divide 30 by 415, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 128085.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
300 divided by 415 is 0 with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 128085.0
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 128085.0 and a remainder of 0.3.
