We're dividing 75135563 by 491 
Let's see how many times 491 fits into 75135563.

Let's proceed to step 1:
When dividing 7 by 491, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 491

Advancing to step 2:
491 can be fit into 75 0 times, resulting in a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 491

Step 3:
The number 491 fits into 751 1 times, leaving a remainder of 260.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 491 from 751, we get 260.
Include the next digit (3) from the dividend after 260, then repeat: 2603 / 491

Let's proceed to step 4:
When dividing 2603 by 491, we get 5 with a remainder of 148.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 148 after subtracting 2455 from 2603.
Take the next digit (5) from the dividend and append it to 148, then repeat: 1485 / 491

On to step 5:
491 goes into 1485 3 times with a remainder of 12.
The next digit of our result is 3. 
Result so far: 153.0
Subtracting 1473 from 1485 leaves us with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 491

Moving on to step 6:
If we divide 125 by 491, we get 0 and a remainder of 125.
The number 0 becomes the next digit in our result. 
Result so far: 1530.0
Deduct 0 from 125 and we're left with 125.
Append the next digit (6) from the dividend to 125 and continue with: 1256 / 491

Going ahead to step 7:
491 can be fit into 1256 2 times, resulting in a remainder of 274.
The next digit of our result is 2. 
Result so far: 15302.0
The remainder is 274 after subtracting 982 from 1256.
Take the next digit (3) from the dividend and append it to 274, then repeat: 2743 / 491

Let's proceed to step 8:
2743 divided by 491 is 5 with a remainder of 288.
Use 5 as the next digit of our solution. 
Result so far: 153025.0
Subtract 2455 from 2743 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 9:
491 can be fit into 2880 5 times, resulting in a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 153025.5
Deduct 2455 from 2880 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 10:
491 goes into 4250 8 times with a remainder of 322.
The next digit of our result is 8. 
Result so far: 153025.58
Deduct 3928 from 4250 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 11:
When dividing 3220 by 491, we get 6 with a remainder of 274.
The number 6 becomes the next digit in our result. 
Result so far: 153025.586
Subtract 2946 from 3220 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 12:
491 goes into 2740 5 times with a remainder of 285.
Use 5 as the next digit of our solution. 
Result so far: 153025.5865
Subtracting 2455 from 2740 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 13:
491 can be fit into 2850 5 times, resulting in a remainder of 395.
Record the quotient 5 as the next digit in the result. 
Result so far: 153025.58655
Subtract 2455 from 2850 to get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

The final outcome is 153025.58655, with a leftover of 0.000395.
