We look at the division of 6432491 by 517 
We're looking to find how many times 517 goes into 6432491.

Let's proceed to step 1:
517 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 517

Let's proceed to step 2:
64 divided by 517 is 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (3) from the dividend, add it to 64, then carry on: 643 / 517

Moving on to step 3:
When dividing 643 by 517, we get 1 with a remainder of 126.
The next digit of our result is 1. 
Result so far: 1.0
If we take 517 away from 643, we end up with 126.
Take the next digit (2) from the dividend and append it to 126, then repeat: 1262 / 517

Moving on to step 4:
If we divide 1262 by 517, we get 2 and a remainder of 228.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 1034 away from 1262, we end up with 228.
Grab the next digit (4) from the dividend, add it to 228, then carry on: 2284 / 517

Step 5:
When dividing 2284 by 517, we get 4 with a remainder of 216.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
If we subtract 2068 from 2284, we get 216.
Include the next digit (9) from the dividend after 216, then repeat: 2169 / 517

Moving on to step 6:
517 goes into 2169 4 times with a remainder of 101.
Write down 4 as next digit of the result. 
Result so far: 1244.0
Subtract 2068 from 2169 to get 101.
Bring next digit (1) of the dividend behind the 101 and repeat the process: 1011 / 517

Going ahead to step 7:
If we divide 1011 by 517, we get 1 and a remainder of 494.
Write down 1 as next digit of the result. 
Result so far: 12441.0
Subtracting 517 from 1011 leaves us with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 8:
The number 517 fits into 4940 9 times, leaving a remainder of 287.
Record the quotient 9 as the next digit in the result. 
Result so far: 12441.9
Subtract 4653 from 4940 to get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Let's proceed to step 9:
517 can be fit into 2870 5 times, resulting in a remainder of 285.
Put 5 as the next digit of the answer. 
Result so far: 12441.95
The remainder is 285 after subtracting 2585 from 2870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 10:
If we divide 2850 by 517, we get 5 and a remainder of 265.
Put 5 as the next digit of the answer. 
Result so far: 12441.955
Deduct 2585 from 2850 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

The final result is 12441.955 with a remainder of 0.0265.
