67742548 ÷ 513 
The aim is to understand the frequency of 513 in 67742548.

Moving on to step 1:
When dividing 6 by 513, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 513

Step 2:
513 goes into 67 0 times with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Fetch the next digit (7) from the dividend, attach it to 67 and continue: 677 / 513

On to step 3:
513 goes into 677 1 times with a remainder of 164.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 513 from 677 leaves us with 164.
Bring next digit (4) of the dividend behind the 164 and repeat the process: 1644 / 513

Step 4:
The number 513 fits into 1644 3 times, leaving a remainder of 105.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1539 from 1644 leaves us with 105.
Fetch the next digit (2) from the dividend, attach it to 105 and continue: 1052 / 513

Going ahead to step 5:
513 can be fit into 1052 2 times, resulting in a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 132.0
If we take 1026 away from 1052, we end up with 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 513

Moving on to step 6:
If we divide 265 by 513, we get 0 and a remainder of 265.
Write down 0 as next digit of the result. 
Result so far: 1320.0
Deduct 0 from 265 and we're left with 265.
Bring next digit (4) of the dividend behind the 265 and repeat the process: 2654 / 513

Let's proceed to step 7:
If we divide 2654 by 513, we get 5 and a remainder of 89.
Write down 5 as next digit of the result. 
Result so far: 13205.0
If we subtract 2565 from 2654, we get 89.
Bring next digit (8) of the dividend behind the 89 and repeat the process: 898 / 513

Going ahead to step 8:
898 divided by 513 is 1 with a remainder of 385.
The number 1 becomes the next digit in our result. 
Result so far: 132051.0
Subtracting 513 from 898 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 9:
3850 divided by 513 is 7 with a remainder of 259.
Use 7 as the next digit of our solution. 
Result so far: 132051.7
Subtracting 3591 from 3850 leaves us with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 10:
The number 513 fits into 2590 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 132051.75
The remainder is 25 after subtracting 2565 from 2590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
If we divide 250 by 513, we get 0 and a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 132051.75
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 12:
When dividing 2500 by 513, we get 4 with a remainder of 448.
Put 4 as the next digit of the answer. 
Result so far: 132051.7504
If we take 2052 away from 2500, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 13:
513 can be fit into 4480 8 times, resulting in a remainder of 376.
The next digit of our result is 8. 
Result so far: 132051.75048
If we take 4104 away from 4480, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 14:
3760 divided by 513 is 7 with a remainder of 169.
The number 7 becomes the next digit in our result. 
Result so far: 132051.750487
If we take 3591 away from 3760, we end up with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Going ahead to step 15:
The number 513 fits into 1690 3 times, leaving a remainder of 151.
The next digit of our result is 3. 
Result so far: 132051.7504873
If we subtract 1539 from 1690, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Moving on to step 16:
513 goes into 1510 2 times with a remainder of 484.
Use 2 as the next digit of our solution. 
Result so far: 132051.75048732
Deduct 1026 from 1510 and we're left with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

After the division, we end up with 132051.75048732 and a remainder of 4.84e-07.
