We're dividing 13069573 by 587 
The aim is to understand the frequency of 587 in 13069573.

Going ahead to step 1:
587 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 587

Step 2:
587 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 587

On to step 3:
587 goes into 130 0 times with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 130, we get 130.
Append the next digit (6) from the dividend to 130 and continue with: 1306 / 587

Going ahead to step 4:
The number 587 fits into 1306 2 times, leaving a remainder of 132.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1174 away from 1306, we end up with 132.
Bring next digit (9) of the dividend behind the 132 and repeat the process: 1329 / 587

Step 5:
If we divide 1329 by 587, we get 2 and a remainder of 155.
The next digit of our result is 2. 
Result so far: 22.0
If we take 1174 away from 1329, we end up with 155.
Append the next digit (5) from the dividend to 155 and continue with: 1555 / 587

Going ahead to step 6:
1555 divided by 587 is 2 with a remainder of 381.
The number 2 becomes the next digit in our result. 
Result so far: 222.0
Deduct 1174 from 1555 and we're left with 381.
Grab the next digit (7) from the dividend, add it to 381, then carry on: 3817 / 587

Moving on to step 7:
3817 divided by 587 is 6 with a remainder of 295.
The number 6 becomes the next digit in our result. 
Result so far: 2226.0
Deduct 3522 from 3817 and we're left with 295.
Fetch the next digit (3) from the dividend, attach it to 295 and continue: 2953 / 587

Advancing to step 8:
The number 587 fits into 2953 5 times, leaving a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 22265.0
Deduct 2935 from 2953 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
If we divide 180 by 587, we get 0 and a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 22265.0
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 10:
587 goes into 1800 3 times with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 22265.03
Deduct 1761 from 1800 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 11:
587 goes into 390 0 times with a remainder of 390.
Write down 0 as next digit of the result. 
Result so far: 22265.03
If we take 0 away from 390, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 12:
587 goes into 3900 6 times with a remainder of 378.
Record the quotient 6 as the next digit in the result. 
Result so far: 22265.0306
Subtracting 3522 from 3900 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 13:
587 can be fit into 3780 6 times, resulting in a remainder of 258.
Use 6 as the next digit of our solution. 
Result so far: 22265.03066
Deduct 3522 from 3780 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Our division results in 22265.03066 with a remaining 0.000258.
