Let's divide 4346021 by 510
We're looking to find how many times 510 goes into 4346021.

Let's proceed to step 1:
When dividing 4 by 510, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 510

Advancing to step 2:
510 goes into 43 0 times with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (4) from the dividend to 43 and continue with: 434 / 510

Let's proceed to step 3:
434 divided by 510 is 0 with a remainder of 434.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 434 to get 434.
Take the next digit (6) from the dividend and append it to 434, then repeat: 4346 / 510

Let's proceed to step 4:
When dividing 4346 by 510, we get 8 with a remainder of 266.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 4080 from 4346 and we're left with 266.
Include the next digit (0) from the dividend after 266, then repeat: 2660 / 510

Let's proceed to step 5:
510 goes into 2660 5 times with a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Deduct 2550 from 2660 and we're left with 110.
Include the next digit (2) from the dividend after 110, then repeat: 1102 / 510

Going ahead to step 6:
510 can be fit into 1102 2 times, resulting in a remainder of 82.
Write down 2 as next digit of the result. 
Result so far: 852.0
The remainder is 82 after subtracting 1020 from 1102.
Append the next digit (1) from the dividend to 82 and continue with: 821 / 510

Advancing to step 7:
If we divide 821 by 510, we get 1 and a remainder of 311.
Put 1 as the next digit of the answer. 
Result so far: 8521.0
Subtracting 510 from 821 leaves us with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 8:
3110 divided by 510 is 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 8521.6
Subtracting 3060 from 3110 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
510 goes into 500 0 times with a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 8521.6
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 10:
If we divide 5000 by 510, we get 9 and a remainder of 410.
Put 9 as the next digit of the answer. 
Result so far: 8521.609
Subtracting 4590 from 5000 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 11:
4100 divided by 510 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 8521.6098
If we take 4080 away from 4100, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
510 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 8521.6098
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 13:
When dividing 2000 by 510, we get 3 with a remainder of 470.
The next digit of our result is 3. 
Result so far: 8521.609803
Subtracting 1530 from 2000 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 14:
510 goes into 4700 9 times with a remainder of 110.
The next digit of our result is 9. 
Result so far: 8521.6098039
If we subtract 4590 from 4700, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 15:
510 goes into 1100 2 times with a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 8521.60980392
Subtract 1020 from 1100 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 8521.60980392 with a remainder of 8e-08.
