We're dividing 68233889 by 510 
We want to figure out the number of times 68233889 can be divided by 510.

On to step 1:
510 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 510

Let's proceed to step 2:
510 goes into 68 0 times with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Bring next digit (2) of the dividend behind the 68 and repeat the process: 682 / 510

Moving on to step 3:
When dividing 682 by 510, we get 1 with a remainder of 172.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 510 from 682, we get 172.
Grab the next digit (3) from the dividend, add it to 172, then carry on: 1723 / 510

Moving on to step 4:
510 goes into 1723 3 times with a remainder of 193.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1530 from 1723 leaves us with 193.
Grab the next digit (3) from the dividend, add it to 193, then carry on: 1933 / 510

Step 5:
510 goes into 1933 3 times with a remainder of 403.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
Subtract 1530 from 1933 to get 403.
Grab the next digit (8) from the dividend, add it to 403, then carry on: 4038 / 510

Step 6:
When dividing 4038 by 510, we get 7 with a remainder of 468.
Use 7 as the next digit of our solution. 
Result so far: 1337.0
Subtract 3570 from 4038 to get 468.
Grab the next digit (8) from the dividend, add it to 468, then carry on: 4688 / 510

Moving on to step 7:
When dividing 4688 by 510, we get 9 with a remainder of 98.
Record the quotient 9 as the next digit in the result. 
Result so far: 13379.0
Subtract 4590 from 4688 to get 98.
Append the next digit (9) from the dividend to 98 and continue with: 989 / 510

Moving on to step 8:
When dividing 989 by 510, we get 1 with a remainder of 479.
Record the quotient 1 as the next digit in the result. 
Result so far: 133791.0
If we take 510 away from 989, we end up with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Step 9:
510 can be fit into 4790 9 times, resulting in a remainder of 200.
Use 9 as the next digit of our solution. 
Result so far: 133791.9
Deduct 4590 from 4790 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 10:
If we divide 2000 by 510, we get 3 and a remainder of 470.
The next digit of our result is 3. 
Result so far: 133791.93
If we take 1530 away from 2000, 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.

On to step 11:
The number 510 fits into 4700 9 times, leaving a remainder of 110.
The next digit of our result is 9. 
Result so far: 133791.939
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.

Going ahead to step 12:
510 can be fit into 1100 2 times, resulting in a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 133791.9392
Subtracting 1020 from 1100 leaves us 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.

Moving on to step 13:
510 goes into 800 1 times with a remainder of 290.
Use 1 as the next digit of our solution. 
Result so far: 133791.93921
The remainder is 290 after subtracting 510 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 14:
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: 133791.939215
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.

Moving on to step 15:
510 can be fit into 3500 6 times, resulting in a remainder of 440.
The number 6 becomes the next digit in our result. 
Result so far: 133791.9392156
The remainder is 440 after subtracting 3060 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 16:
4400 divided by 510 is 8 with a remainder of 320.
Put 8 as the next digit of the answer. 
Result so far: 133791.93921568
If we take 4080 away from 4400, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

In conclusion, the division gives 133791.93921568 with a balance of 3.2e-07.
