We look at the division of 53780539 by 387 
We're looking to find how many times 387 goes into 53780539.

Advancing to step 1:
5 divided by 387 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 387

Going ahead to step 2:
53 divided by 387 is 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Include the next digit (7) from the dividend after 53, then repeat: 537 / 387

Going ahead to step 3:
When dividing 537 by 387, we get 1 with a remainder of 150.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 387 from 537, we get 150.
Append the next digit (8) from the dividend to 150 and continue with: 1508 / 387

Moving on to step 4:
If we divide 1508 by 387, we get 3 and a remainder of 347.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 1161 from 1508 leaves us with 347.
Fetch the next digit (0) from the dividend, attach it to 347 and continue: 3470 / 387

Let's proceed to step 5:
If we divide 3470 by 387, we get 8 and a remainder of 374.
The next digit of our result is 8. 
Result so far: 138.0
Deduct 3096 from 3470 and we're left with 374.
Bring next digit (5) of the dividend behind the 374 and repeat the process: 3745 / 387

Let's proceed to step 6:
387 can be fit into 3745 9 times, resulting in a remainder of 262.
The next digit of our result is 9. 
Result so far: 1389.0
Deduct 3483 from 3745 and we're left with 262.
Append the next digit (3) from the dividend to 262 and continue with: 2623 / 387

Going ahead to step 7:
387 goes into 2623 6 times with a remainder of 301.
Record the quotient 6 as the next digit in the result. 
Result so far: 13896.0
The remainder is 301 after subtracting 2322 from 2623.
Fetch the next digit (9) from the dividend, attach it to 301 and continue: 3019 / 387

Step 8:
3019 divided by 387 is 7 with a remainder of 310.
Write down 7 as next digit of the result. 
Result so far: 138967.0
If we take 2709 away from 3019, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 9:
The number 387 fits into 3100 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 138967.8
Deduct 3096 from 3100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
387 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 138967.8
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
The number 387 fits into 400 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 138967.801
The remainder is 13 after subtracting 387 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
387 can be fit into 130 0 times, resulting in a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 138967.801
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 13:
387 goes into 1300 3 times with a remainder of 139.
The number 3 becomes the next digit in our result. 
Result so far: 138967.80103
The remainder is 139 after subtracting 1161 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 14:
When dividing 1390 by 387, we get 3 with a remainder of 229.
The next digit of our result is 3. 
Result so far: 138967.801033
If we subtract 1161 from 1390, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

The final result is 138967.801033 with a remainder of 2.29e-05.
