We look at the division of 36619788 by 580 
The aim is to understand the frequency of 580 in 36619788.

Advancing to step 1:
3 divided by 580 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 580

Moving on to step 2:
When dividing 36 by 580, we get 0 with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 580

On to step 3:
580 can be fit into 366 0 times, resulting in a remainder of 366.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 366 after subtracting 0 from 366.
Bring next digit (1) of the dividend behind the 366 and repeat the process: 3661 / 580

Let's proceed to step 4:
3661 divided by 580 is 6 with a remainder of 181.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 3480 from 3661 and we're left with 181.
Fetch the next digit (9) from the dividend, attach it to 181 and continue: 1819 / 580

Moving on to step 5:
580 goes into 1819 3 times with a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 63.0
If we take 1740 away from 1819, we end up with 79.
Fetch the next digit (7) from the dividend, attach it to 79 and continue: 797 / 580

On to step 6:
580 goes into 797 1 times with a remainder of 217.
Write down 1 as next digit of the result. 
Result so far: 631.0
If we take 580 away from 797, we end up with 217.
Grab the next digit (8) from the dividend, add it to 217, then carry on: 2178 / 580

Moving on to step 7:
The number 580 fits into 2178 3 times, leaving a remainder of 438.
The number 3 becomes the next digit in our result. 
Result so far: 6313.0
Subtract 1740 from 2178 to get 438.
Append the next digit (8) from the dividend to 438 and continue with: 4388 / 580

Advancing to step 8:
If we divide 4388 by 580, we get 7 and a remainder of 328.
Use 7 as the next digit of our solution. 
Result so far: 63137.0
Subtract 4060 from 4388 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 9:
580 can be fit into 3280 5 times, resulting in a remainder of 380.
The number 5 becomes the next digit in our result. 
Result so far: 63137.5
If we subtract 2900 from 3280, we get 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 10:
3800 divided by 580 is 6 with a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 63137.56
If we subtract 3480 from 3800, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 11:
If we divide 3200 by 580, we get 5 and a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 63137.565
The remainder is 300 after subtracting 2900 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 12:
580 can be fit into 3000 5 times, resulting in a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 63137.5655
Subtract 2900 from 3000 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 63137.5655 with a remainder of 0.001.
