We divide 68170341 by 513
The aim is to understand the frequency of 513 in 68170341.

Step 1:
513 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
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:
The number 513 fits into 68 0 times, leaving a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Take the next digit (1) from the dividend and append it to 68, then repeat: 681 / 513

Moving on to step 3:
The number 513 fits into 681 1 times, leaving a remainder of 168.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 513 away from 681, we end up with 168.
Fetch the next digit (7) from the dividend, attach it to 168 and continue: 1687 / 513

Advancing to step 4:
513 goes into 1687 3 times with a remainder of 148.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 1539 from 1687 leaves us with 148.
Fetch the next digit (0) from the dividend, attach it to 148 and continue: 1480 / 513

Let's proceed to step 5:
1480 divided by 513 is 2 with a remainder of 454.
The number 2 becomes the next digit in our result. 
Result so far: 132.0
The remainder is 454 after subtracting 1026 from 1480.
Bring next digit (3) of the dividend behind the 454 and repeat the process: 4543 / 513

Moving on to step 6:
4543 divided by 513 is 8 with a remainder of 439.
Write down 8 as next digit of the result. 
Result so far: 1328.0
Deduct 4104 from 4543 and we're left with 439.
Fetch the next digit (4) from the dividend, attach it to 439 and continue: 4394 / 513

Going ahead to step 7:
When dividing 4394 by 513, we get 8 with a remainder of 290.
Put 8 as the next digit of the answer. 
Result so far: 13288.0
Subtract 4104 from 4394 to get 290.
Append the next digit (1) from the dividend to 290 and continue with: 2901 / 513

Going ahead to step 8:
513 goes into 2901 5 times with a remainder of 336.
The next digit of our result is 5. 
Result so far: 132885.0
If we take 2565 away from 2901, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 9:
513 can be fit into 3360 6 times, resulting in a remainder of 282.
The next digit of our result is 6. 
Result so far: 132885.6
Subtracting 3078 from 3360 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 10:
513 can be fit into 2820 5 times, resulting in a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 132885.65
If we subtract 2565 from 2820, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 11:
513 goes into 2550 4 times with a remainder of 498.
The next digit of our result is 4. 
Result so far: 132885.654
Subtract 2052 from 2550 to get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Advancing to step 12:
If we divide 4980 by 513, we get 9 and a remainder of 363.
Put 9 as the next digit of the answer. 
Result so far: 132885.6549
Subtract 4617 from 4980 to get 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Let's proceed to step 13:
513 goes into 3630 7 times with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 132885.65497
Subtract 3591 from 3630 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 14:
The number 513 fits into 390 0 times, leaving a remainder of 390.
Use 0 as the next digit of our solution. 
Result so far: 132885.65497
Subtract 0 from 390 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 15:
If we divide 3900 by 513, we get 7 and a remainder of 309.
Use 7 as the next digit of our solution. 
Result so far: 132885.6549707
Deduct 3591 from 3900 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Step 16:
513 can be fit into 3090 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 132885.65497076
If we take 3078 away from 3090, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 132885.65497076 with a remainder of 1.2e-08.
