Let's divide 72135033 by 579
The aim is to understand the frequency of 579 in 72135033.

Let's proceed to step 1:
If we divide 7 by 579, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 579

Going ahead to step 2:
When dividing 72 by 579, we get 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 579

Let's proceed to step 3:
If we divide 721 by 579, we get 1 and a remainder of 142.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 579 from 721 and we're left with 142.
Take the next digit (3) from the dividend and append it to 142, then repeat: 1423 / 579

Let's proceed to step 4:
579 goes into 1423 2 times with a remainder of 265.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1158 from 1423 to get 265.
Take the next digit (5) from the dividend and append it to 265, then repeat: 2655 / 579

Let's proceed to step 5:
2655 divided by 579 is 4 with a remainder of 339.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
Deduct 2316 from 2655 and we're left with 339.
Take the next digit (0) from the dividend and append it to 339, then repeat: 3390 / 579

On to step 6:
When dividing 3390 by 579, we get 5 with a remainder of 495.
Put 5 as the next digit of the answer. 
Result so far: 1245.0
If we take 2895 away from 3390, we end up with 495.
Include the next digit (3) from the dividend after 495, then repeat: 4953 / 579

Advancing to step 7:
If we divide 4953 by 579, we get 8 and a remainder of 321.
Put 8 as the next digit of the answer. 
Result so far: 12458.0
If we subtract 4632 from 4953, we get 321.
Bring next digit (3) of the dividend behind the 321 and repeat the process: 3213 / 579

On to step 8:
If we divide 3213 by 579, we get 5 and a remainder of 318.
The number 5 becomes the next digit in our result. 
Result so far: 124585.0
The remainder is 318 after subtracting 2895 from 3213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 9:
When dividing 3180 by 579, we get 5 with a remainder of 285.
Write down 5 as next digit of the result. 
Result so far: 124585.5
If we subtract 2895 from 3180, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 10:
The number 579 fits into 2850 4 times, leaving a remainder of 534.
Use 4 as the next digit of our solution. 
Result so far: 124585.54
Subtracting 2316 from 2850 leaves us with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Moving on to step 11:
When dividing 5340 by 579, we get 9 with a remainder of 129.
Put 9 as the next digit of the answer. 
Result so far: 124585.549
Subtracting 5211 from 5340 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 12:
If we divide 1290 by 579, we get 2 and a remainder of 132.
Write down 2 as next digit of the result. 
Result so far: 124585.5492
Subtract 1158 from 1290 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 13:
If we divide 1320 by 579, we get 2 and a remainder of 162.
Record the quotient 2 as the next digit in the result. 
Result so far: 124585.54922
If we subtract 1158 from 1320, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

After the division, we end up with 124585.54922 and a remainder of 0.000162.
