Let's divide 4394212 by 510
Our goal is to divide 4394212 by 510.

Step 1:
When dividing 4 by 510, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 510

Advancing to step 2:
43 divided by 510 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 510

On to step 3:
510 goes into 439 0 times with a remainder of 439.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 439, we get 439.
Append the next digit (4) from the dividend to 439 and continue with: 4394 / 510

Let's proceed to step 4:
4394 divided by 510 is 8 with a remainder of 314.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 314 after subtracting 4080 from 4394.
Include the next digit (2) from the dividend after 314, then repeat: 3142 / 510

Moving on to step 5:
The number 510 fits into 3142 6 times, leaving a remainder of 82.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Subtract 3060 from 3142 to get 82.
Take the next digit (1) from the dividend and append it to 82, then repeat: 821 / 510

Step 6:
510 goes into 821 1 times with a remainder of 311.
Put 1 as the next digit of the answer. 
Result so far: 861.0
Subtracting 510 from 821 leaves us with 311.
Take the next digit (2) from the dividend and append it to 311, then repeat: 3112 / 510

Moving on to step 7:
510 goes into 3112 6 times with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 8616.0
If we take 3060 away from 3112, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 8:
If we divide 520 by 510, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 8616.1
The remainder is 10 after subtracting 510 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
510 goes into 100 0 times with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 8616.1
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 10:
If we divide 1000 by 510, we get 1 and a remainder of 490.
Use 1 as the next digit of our solution. 
Result so far: 8616.101
Subtracting 510 from 1000 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 11:
The number 510 fits into 4900 9 times, leaving a remainder of 310.
Use 9 as the next digit of our solution. 
Result so far: 8616.1019
If we subtract 4590 from 4900, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 12:
510 goes into 3100 6 times with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 8616.10196
Subtract 3060 from 3100 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
If we divide 400 by 510, we get 0 and a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 8616.10196
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 14:
510 can be fit into 4000 7 times, resulting in a remainder of 430.
Put 7 as the next digit of the answer. 
Result so far: 8616.1019607
Subtract 3570 from 4000 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 15:
If we divide 4300 by 510, we get 8 and a remainder of 220.
Put 8 as the next digit of the answer. 
Result so far: 8616.10196078
If we subtract 4080 from 4300, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

After the division, we end up with 8616.10196078 and a remainder of 2.2e-07.
