We look at the division of 24721 by 35 
The aim is to understand the frequency of 35 in 24721.

Advancing to step 1:
35 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 35

Going ahead to step 2:
24 divided by 35 is 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Append the next digit (7) from the dividend to 24 and continue with: 247 / 35

Advancing to step 3:
When dividing 247 by 35, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 245 away from 247, we end up with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 35

Going ahead to step 4:
If we divide 22 by 35, we get 0 and a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 70.0
If we take 0 away from 22, we end up with 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 35

Moving on to step 5:
The number 35 fits into 221 6 times, leaving a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 706.0
Subtracting 210 from 221 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 6:
The number 35 fits into 110 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 706.3
Subtracting 105 from 110 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.

Advancing to step 7:
If we divide 50 by 35, we get 1 and a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 706.31
The remainder is 15 after subtracting 35 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
35 goes into 150 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 706.314
Subtract 140 from 150 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
100 divided by 35 is 2 with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 706.3142
If we take 70 away from 100, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
When dividing 300 by 35, we get 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 706.31428
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
If we divide 200 by 35, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 706.314285
The remainder is 25 after subtracting 175 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 12:
If we divide 250 by 35, we get 7 and a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 706.3142857
Deduct 245 from 250 and we're left 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.

Let's proceed to step 13:
If we divide 50 by 35, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 706.31428571
The remainder is 15 after subtracting 35 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 706.31428571 with a remaining 1.5e-08.
