We divide 1710255 by 621
We're looking to find how many times 621 goes into 1710255.

Advancing to step 1:
621 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 621

On to step 2:
The number 621 fits into 17 0 times, leaving a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 621

Let's proceed to step 3:
When dividing 171 by 621, we get 0 with a remainder of 171.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 171, we end up with 171.
Include the next digit (0) from the dividend after 171, then repeat: 1710 / 621

Moving on to step 4:
1710 divided by 621 is 2 with a remainder of 468.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 1242 away from 1710, we end up with 468.
Grab the next digit (2) from the dividend, add it to 468, then carry on: 4682 / 621

Advancing to step 5:
The number 621 fits into 4682 7 times, leaving a remainder of 335.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtracting 4347 from 4682 leaves us with 335.
Include the next digit (5) from the dividend after 335, then repeat: 3355 / 621

Advancing to step 6:
3355 divided by 621 is 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 275.0
Subtracting 3105 from 3355 leaves us with 250.
Append the next digit (5) from the dividend to 250 and continue with: 2505 / 621

Step 7:
621 can be fit into 2505 4 times, resulting in a remainder of 21.
The next digit of our result is 4. 
Result so far: 2754.0
If we take 2484 away from 2505, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
210 divided by 621 is 0 with a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 2754.0
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 9:
621 can be fit into 2100 3 times, resulting in a remainder of 237.
Write down 3 as next digit of the result. 
Result so far: 2754.03
Subtracting 1863 from 2100 leaves us with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Advancing to step 10:
If we divide 2370 by 621, we get 3 and a remainder of 507.
Write down 3 as next digit of the result. 
Result so far: 2754.033
Deduct 1863 from 2370 and we're left with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

The final result is 2754.033 with a remainder of 0.0507.
