We look at the division of 58602281 by 613 
The aim is to understand the frequency of 613 in 58602281.

Going ahead to step 1:
When dividing 5 by 613, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 613

Advancing to step 2:
613 goes into 58 0 times with a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Append the next digit (6) from the dividend to 58 and continue with: 586 / 613

On to step 3:
The number 613 fits into 586 0 times, leaving a remainder of 586.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 586, we end up with 586.
Append the next digit (0) from the dividend to 586 and continue with: 5860 / 613

Going ahead to step 4:
When dividing 5860 by 613, we get 9 with a remainder of 343.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 5517 from 5860 leaves us with 343.
Bring next digit (2) of the dividend behind the 343 and repeat the process: 3432 / 613

Step 5:
613 goes into 3432 5 times with a remainder of 367.
Use 5 as the next digit of our solution. 
Result so far: 95.0
If we subtract 3065 from 3432, we get 367.
Take the next digit (2) from the dividend and append it to 367, then repeat: 3672 / 613

Going ahead to step 6:
If we divide 3672 by 613, we get 5 and a remainder of 607.
Record the quotient 5 as the next digit in the result. 
Result so far: 955.0
Subtract 3065 from 3672 to get 607.
Take the next digit (8) from the dividend and append it to 607, then repeat: 6078 / 613

Step 7:
6078 divided by 613 is 9 with a remainder of 561.
Write down 9 as next digit of the result. 
Result so far: 9559.0
Deduct 5517 from 6078 and we're left with 561.
Take the next digit (1) from the dividend and append it to 561, then repeat: 5611 / 613

Going ahead to step 8:
If we divide 5611 by 613, we get 9 and a remainder of 94.
Use 9 as the next digit of our solution. 
Result so far: 95599.0
The remainder is 94 after subtracting 5517 from 5611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 9:
If we divide 940 by 613, we get 1 and a remainder of 327.
The number 1 becomes the next digit in our result. 
Result so far: 95599.1
If we subtract 613 from 940, we get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Moving on to step 10:
613 can be fit into 3270 5 times, resulting in a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 95599.15
Subtracting 3065 from 3270 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 11:
The number 613 fits into 2050 3 times, leaving a remainder of 211.
Record the quotient 3 as the next digit in the result. 
Result so far: 95599.153
Subtracting 1839 from 2050 leaves us with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 12:
2110 divided by 613 is 3 with a remainder of 271.
Put 3 as the next digit of the answer. 
Result so far: 95599.1533
If we take 1839 away from 2110, we end up with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

After the division, we end up with 95599.1533 and a remainder of 0.00271.
