68697353 divided by 510 
We want to figure out the number of times 68697353 can be divided by 510.

Advancing to step 1:
When dividing 6 by 510, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 510

Advancing to step 2:
If we divide 68 by 510, we get 0 and a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Include the next digit (6) from the dividend after 68, then repeat: 686 / 510

Step 3:
510 can be fit into 686 1 times, resulting in a remainder of 176.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 510 from 686, we get 176.
Append the next digit (9) from the dividend to 176 and continue with: 1769 / 510

Moving on to step 4:
1769 divided by 510 is 3 with a remainder of 239.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1530 from 1769 to get 239.
Take the next digit (7) from the dividend and append it to 239, then repeat: 2397 / 510

Advancing to step 5:
If we divide 2397 by 510, we get 4 and a remainder of 357.
Use 4 as the next digit of our solution. 
Result so far: 134.0
The remainder is 357 after subtracting 2040 from 2397.
Bring next digit (3) of the dividend behind the 357 and repeat the process: 3573 / 510

Step 6:
If we divide 3573 by 510, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 1347.0
The remainder is 3 after subtracting 3570 from 3573.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 510

Moving on to step 7:
510 goes into 35 0 times with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 13470.0
If we subtract 0 from 35, we get 35.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 510

Moving on to step 8:
353 divided by 510 is 0 with a remainder of 353.
The number 0 becomes the next digit in our result. 
Result so far: 134700.0
Subtract 0 from 353 to get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Step 9:
510 can be fit into 3530 6 times, resulting in a remainder of 470.
The next digit of our result is 6. 
Result so far: 134700.6
If we take 3060 away from 3530, we end up 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 10:
If we divide 4700 by 510, we get 9 and a remainder of 110.
Record the quotient 9 as the next digit in the result. 
Result so far: 134700.69
The remainder is 110 after subtracting 4590 from 4700.
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 11:
The number 510 fits into 1100 2 times, leaving a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 134700.692
Deduct 1020 from 1100 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
When dividing 800 by 510, we get 1 with a remainder of 290.
The next digit of our result is 1. 
Result so far: 134700.6921
If we subtract 510 from 800, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 13:
If we divide 2900 by 510, we get 5 and a remainder of 350.
The next digit of our result is 5. 
Result so far: 134700.69215
If we take 2550 away from 2900, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 14:
When dividing 3500 by 510, we get 6 with a remainder of 440.
Record the quotient 6 as the next digit in the result. 
Result so far: 134700.692156
If we take 3060 away from 3500, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 15:
510 goes into 4400 8 times with a remainder of 320.
Record the quotient 8 as the next digit in the result. 
Result so far: 134700.6921568
Subtract 4080 from 4400 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 16:
The number 510 fits into 3200 6 times, leaving a remainder of 140.
Use 6 as the next digit of our solution. 
Result so far: 134700.69215686
If we subtract 3060 from 3200, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final outcome is 134700.69215686, with a leftover of 1.4e-07.
