We look at the division of 53654496 by 586 
The aim is to understand the frequency of 586 in 53654496.

Moving on to step 1:
5 divided by 586 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 586

Going ahead to step 2:
If we divide 53 by 586, we get 0 and a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Bring next digit (6) of the dividend behind the 53 and repeat the process: 536 / 586

On to step 3:
The number 586 fits into 536 0 times, leaving a remainder of 536.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 536, we get 536.
Append the next digit (5) from the dividend to 536 and continue with: 5365 / 586

Moving on to step 4:
When dividing 5365 by 586, we get 9 with a remainder of 91.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 5274 from 5365, we get 91.
Bring next digit (4) of the dividend behind the 91 and repeat the process: 914 / 586

Moving on to step 5:
586 goes into 914 1 times with a remainder of 328.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Subtracting 586 from 914 leaves us with 328.
Append the next digit (4) from the dividend to 328 and continue with: 3284 / 586

On to step 6:
The number 586 fits into 3284 5 times, leaving a remainder of 354.
The number 5 becomes the next digit in our result. 
Result so far: 915.0
Subtracting 2930 from 3284 leaves us with 354.
Include the next digit (9) from the dividend after 354, then repeat: 3549 / 586

Step 7:
586 can be fit into 3549 6 times, resulting in a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 9156.0
If we take 3516 away from 3549, we end up with 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 586

Step 8:
The number 586 fits into 336 0 times, leaving a remainder of 336.
Use 0 as the next digit of our solution. 
Result so far: 91560.0
Subtract 0 from 336 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 9:
If we divide 3360 by 586, we get 5 and a remainder of 430.
Use 5 as the next digit of our solution. 
Result so far: 91560.5
If we subtract 2930 from 3360, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 10:
586 goes into 4300 7 times with a remainder of 198.
Put 7 as the next digit of the answer. 
Result so far: 91560.57
If we take 4102 away from 4300, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Let's proceed to step 11:
The number 586 fits into 1980 3 times, leaving a remainder of 222.
Use 3 as the next digit of our solution. 
Result so far: 91560.573
Subtract 1758 from 1980 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 12:
2220 divided by 586 is 3 with a remainder of 462.
The next digit of our result is 3. 
Result so far: 91560.5733
The remainder is 462 after subtracting 1758 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

After the division, we end up with 91560.5733 and a remainder of 0.00462.
