We're dividing 13505586 by 715 
The aim is to understand the frequency of 715 in 13505586.

Let's proceed to step 1:
1 divided by 715 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 715

Step 2:
The number 715 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 715

Step 3:
The number 715 fits into 135 0 times, leaving a remainder of 135.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 135, we get 135.
Include the next digit (0) from the dividend after 135, then repeat: 1350 / 715

On to step 4:
715 can be fit into 1350 1 times, resulting in a remainder of 635.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 715 away from 1350, we end up with 635.
Include the next digit (5) from the dividend after 635, then repeat: 6355 / 715

Advancing to step 5:
If we divide 6355 by 715, we get 8 and a remainder of 635.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 5720 from 6355 and we're left with 635.
Include the next digit (5) from the dividend after 635, then repeat: 6355 / 715

Let's proceed to step 6:
If we divide 6355 by 715, we get 8 and a remainder of 635.
Write down 8 as next digit of the result. 
Result so far: 188.0
If we take 5720 away from 6355, we end up with 635.
Include the next digit (8) from the dividend after 635, then repeat: 6358 / 715

Moving on to step 7:
The number 715 fits into 6358 8 times, leaving a remainder of 638.
The number 8 becomes the next digit in our result. 
Result so far: 1888.0
Subtracting 5720 from 6358 leaves us with 638.
Take the next digit (6) from the dividend and append it to 638, then repeat: 6386 / 715

Moving on to step 8:
If we divide 6386 by 715, we get 8 and a remainder of 666.
Use 8 as the next digit of our solution. 
Result so far: 18888.0
If we subtract 5720 from 6386, we get 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Moving on to step 9:
715 can be fit into 6660 9 times, resulting in a remainder of 225.
Record the quotient 9 as the next digit in the result. 
Result so far: 18888.9
If we take 6435 away from 6660, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 10:
When dividing 2250 by 715, we get 3 with a remainder of 105.
The next digit of our result is 3. 
Result so far: 18888.93
Subtract 2145 from 2250 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 11:
The number 715 fits into 1050 1 times, leaving a remainder of 335.
Record the quotient 1 as the next digit in the result. 
Result so far: 18888.931
The remainder is 335 after subtracting 715 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 12:
715 goes into 3350 4 times with a remainder of 490.
Write down 4 as next digit of the result. 
Result so far: 18888.9314
Subtracting 2860 from 3350 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 13:
715 can be fit into 4900 6 times, resulting in a remainder of 610.
Use 6 as the next digit of our solution. 
Result so far: 18888.93146
Subtract 4290 from 4900 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 14:
715 goes into 6100 8 times with a remainder of 380.
The number 8 becomes the next digit in our result. 
Result so far: 18888.931468
Subtracting 5720 from 6100 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 15:
715 goes into 3800 5 times with a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 18888.9314685
Subtracting 3575 from 3800 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 16:
When dividing 2250 by 715, we get 3 with a remainder of 105.
The number 3 becomes the next digit in our result. 
Result so far: 18888.93146853
Subtracting 2145 from 2250 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final result is 18888.93146853 with a remainder of 1.05e-07.
