We look at the division of 68149238 by 513 
We want to divide 68149238 by 513.

On to step 1:
The number 513 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 513

On to step 2:
If we divide 68 by 513, we get 0 and a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 513

On to step 3:
513 can be fit into 681 1 times, resulting in a remainder of 168.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 513 from 681 to get 168.
Take the next digit (4) from the dividend and append it to 168, then repeat: 1684 / 513

Step 4:
513 goes into 1684 3 times with a remainder of 145.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 1539 from 1684 and we're left with 145.
Bring next digit (9) of the dividend behind the 145 and repeat the process: 1459 / 513

Advancing to step 5:
If we divide 1459 by 513, we get 2 and a remainder of 433.
Use 2 as the next digit of our solution. 
Result so far: 132.0
Deduct 1026 from 1459 and we're left with 433.
Bring next digit (2) of the dividend behind the 433 and repeat the process: 4332 / 513

Moving on to step 6:
When dividing 4332 by 513, we get 8 with a remainder of 228.
The number 8 becomes the next digit in our result. 
Result so far: 1328.0
The remainder is 228 after subtracting 4104 from 4332.
Bring next digit (3) of the dividend behind the 228 and repeat the process: 2283 / 513

Let's proceed to step 7:
513 can be fit into 2283 4 times, resulting in a remainder of 231.
The next digit of our result is 4. 
Result so far: 13284.0
If we take 2052 away from 2283, we end up with 231.
Include the next digit (8) from the dividend after 231, then repeat: 2318 / 513

On to step 8:
If we divide 2318 by 513, we get 4 and a remainder of 266.
The number 4 becomes the next digit in our result. 
Result so far: 132844.0
If we subtract 2052 from 2318, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 9:
The number 513 fits into 2660 5 times, leaving a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 132844.5
Subtracting 2565 from 2660 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 10:
950 divided by 513 is 1 with a remainder of 437.
Use 1 as the next digit of our solution. 
Result so far: 132844.51
Subtracting 513 from 950 leaves us with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Moving on to step 11:
4370 divided by 513 is 8 with a remainder of 266.
Write down 8 as next digit of the result. 
Result so far: 132844.518
Deduct 4104 from 4370 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 12:
If we divide 2660 by 513, we get 5 and a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 132844.5185
Subtract 2565 from 2660 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 13:
513 goes into 950 1 times with a remainder of 437.
Write down 1 as next digit of the result. 
Result so far: 132844.51851
Deduct 513 from 950 and we're left with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Going ahead to step 14:
If we divide 4370 by 513, we get 8 and a remainder of 266.
The next digit of our result is 8. 
Result so far: 132844.518518
Deduct 4104 from 4370 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 15:
513 can be fit into 2660 5 times, resulting in a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 132844.5185185
Deduct 2565 from 2660 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 16:
950 divided by 513 is 1 with a remainder of 437.
Write down 1 as next digit of the result. 
Result so far: 132844.51851851
If we take 513 away from 950, we end up with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

In conclusion, the division gives 132844.51851851 with a balance of 4.37e-07.
