We look at the division of 64607768 by 573 
The aim is to understand the frequency of 573 in 64607768.

Let's proceed to step 1:
6 divided by 573 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 573

Let's proceed to step 2:
If we divide 64 by 573, we get 0 and a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (6) from the dividend and append it to 64, then repeat: 646 / 573

Step 3:
573 goes into 646 1 times with a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 73 after subtracting 573 from 646.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 573

On to step 4:
If we divide 730 by 573, we get 1 and a remainder of 157.
The next digit of our result is 1. 
Result so far: 11.0
If we take 573 away from 730, we end up with 157.
Bring next digit (7) of the dividend behind the 157 and repeat the process: 1577 / 573

Moving on to step 5:
If we divide 1577 by 573, we get 2 and a remainder of 431.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
If we take 1146 away from 1577, we end up with 431.
Bring next digit (7) of the dividend behind the 431 and repeat the process: 4317 / 573

Let's proceed to step 6:
4317 divided by 573 is 7 with a remainder of 306.
Record the quotient 7 as the next digit in the result. 
Result so far: 1127.0
Deduct 4011 from 4317 and we're left with 306.
Grab the next digit (6) from the dividend, add it to 306, then carry on: 3066 / 573

Advancing to step 7:
The number 573 fits into 3066 5 times, leaving a remainder of 201.
Use 5 as the next digit of our solution. 
Result so far: 11275.0
Deduct 2865 from 3066 and we're left with 201.
Bring next digit (8) of the dividend behind the 201 and repeat the process: 2018 / 573

Advancing to step 8:
2018 divided by 573 is 3 with a remainder of 299.
The number 3 becomes the next digit in our result. 
Result so far: 112753.0
If we subtract 1719 from 2018, we get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Moving on to step 9:
When dividing 2990 by 573, we get 5 with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 112753.5
The remainder is 125 after subtracting 2865 from 2990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 10:
573 can be fit into 1250 2 times, resulting in a remainder of 104.
Use 2 as the next digit of our solution. 
Result so far: 112753.52
Deduct 1146 from 1250 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 11:
When dividing 1040 by 573, we get 1 with a remainder of 467.
Put 1 as the next digit of the answer. 
Result so far: 112753.521
Subtract 573 from 1040 to get 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

On to step 12:
If we divide 4670 by 573, we get 8 and a remainder of 86.
Use 8 as the next digit of our solution. 
Result so far: 112753.5218
If we subtract 4584 from 4670, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 13:
When dividing 860 by 573, we get 1 with a remainder of 287.
Put 1 as the next digit of the answer. 
Result so far: 112753.52181
The remainder is 287 after subtracting 573 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

On to step 14:
2870 divided by 573 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 112753.521815
Subtracting 2865 from 2870 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 15:
The number 573 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 112753.521815
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 16:
If we divide 500 by 573, we get 0 and a remainder of 500.
The next digit of our result is 0. 
Result so far: 112753.521815
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 112753.521815 and a remainder of 5e-07.
