Let's divide 39728202 by 510
We want to divide 39728202 by 510.

Advancing to step 1:
The number 510 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 510

Step 2:
When dividing 39 by 510, we get 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 510

Let's proceed to step 3:
510 goes into 397 0 times with a remainder of 397.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 397 to get 397.
Take the next digit (2) from the dividend and append it to 397, then repeat: 3972 / 510

Going ahead to step 4:
3972 divided by 510 is 7 with a remainder of 402.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 3570 from 3972, we get 402.
Fetch the next digit (8) from the dividend, attach it to 402 and continue: 4028 / 510

Let's proceed to step 5:
510 can be fit into 4028 7 times, resulting in a remainder of 458.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
Deduct 3570 from 4028 and we're left with 458.
Take the next digit (2) from the dividend and append it to 458, then repeat: 4582 / 510

Step 6:
510 can be fit into 4582 8 times, resulting in a remainder of 502.
The next digit of our result is 8. 
Result so far: 778.0
Subtract 4080 from 4582 to get 502.
Include the next digit (0) from the dividend after 502, then repeat: 5020 / 510

Step 7:
5020 divided by 510 is 9 with a remainder of 430.
Put 9 as the next digit of the answer. 
Result so far: 7789.0
Subtract 4590 from 5020 to get 430.
Include the next digit (2) from the dividend after 430, then repeat: 4302 / 510

On to step 8:
510 goes into 4302 8 times with a remainder of 222.
The next digit of our result is 8. 
Result so far: 77898.0
Deduct 4080 from 4302 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 9:
If we divide 2220 by 510, we get 4 and a remainder of 180.
Record the quotient 4 as the next digit in the result. 
Result so far: 77898.4
If we take 2040 away from 2220, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 10:
The number 510 fits into 1800 3 times, leaving a remainder of 270.
The number 3 becomes the next digit in our result. 
Result so far: 77898.43
Deduct 1530 from 1800 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 11:
If we divide 2700 by 510, we get 5 and a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 77898.435
Deduct 2550 from 2700 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 12:
510 goes into 1500 2 times with a remainder of 480.
Write down 2 as next digit of the result. 
Result so far: 77898.4352
If we subtract 1020 from 1500, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 13:
510 can be fit into 4800 9 times, resulting in a remainder of 210.
Put 9 as the next digit of the answer. 
Result so far: 77898.43529
Subtracting 4590 from 4800 leaves us 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.

Let's proceed to step 14:
510 can be fit into 2100 4 times, resulting in a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 77898.435294
Subtracting 2040 from 2100 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 15:
If we divide 600 by 510, we get 1 and a remainder of 90.
Use 1 as the next digit of our solution. 
Result so far: 77898.4352941
If we take 510 away from 600, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 16:
The number 510 fits into 900 1 times, leaving a remainder of 390.
Write down 1 as next digit of the result. 
Result so far: 77898.43529411
If we take 510 away from 900, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

The quotient of the division is 77898.43529411, and the remainder is 3.9e-07.
