We divide 1621243 by 517
Our goal is to divide 1621243 by 517.

Moving on to step 1:
517 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 517

Advancing to step 2:
16 divided by 517 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 517

Step 3:
517 can be fit into 162 0 times, resulting in a remainder of 162.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 162, we get 162.
Grab the next digit (1) from the dividend, add it to 162, then carry on: 1621 / 517

Let's proceed to step 4:
517 can be fit into 1621 3 times, resulting in a remainder of 70.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 70 after subtracting 1551 from 1621.
Grab the next digit (2) from the dividend, add it to 70, then carry on: 702 / 517

Moving on to step 5:
517 can be fit into 702 1 times, resulting in a remainder of 185.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 517 from 702 to get 185.
Grab the next digit (4) from the dividend, add it to 185, then carry on: 1854 / 517

Let's proceed to step 6:
517 goes into 1854 3 times with a remainder of 303.
The next digit of our result is 3. 
Result so far: 313.0
If we take 1551 away from 1854, we end up with 303.
Include the next digit (3) from the dividend after 303, then repeat: 3033 / 517

Going ahead to step 7:
When dividing 3033 by 517, we get 5 with a remainder of 448.
The next digit of our result is 5. 
Result so far: 3135.0
If we take 2585 away from 3033, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 8:
517 goes into 4480 8 times with a remainder of 344.
The number 8 becomes the next digit in our result. 
Result so far: 3135.8
Deduct 4136 from 4480 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 9:
3440 divided by 517 is 6 with a remainder of 338.
Record the quotient 6 as the next digit in the result. 
Result so far: 3135.86
Deduct 3102 from 3440 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 10:
517 goes into 3380 6 times with a remainder of 278.
The number 6 becomes the next digit in our result. 
Result so far: 3135.866
Subtracting 3102 from 3380 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Our division results in 3135.866 with a remaining 0.0278.
