Let's divide 30217888 by 658
The aim is to understand the frequency of 658 in 30217888.

On to step 1:
658 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 658

Advancing to step 2:
658 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 658

Going ahead to step 3:
658 can be fit into 302 0 times, resulting in a remainder of 302.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 302 and we're left with 302.
Include the next digit (1) from the dividend after 302, then repeat: 3021 / 658

Moving on to step 4:
658 goes into 3021 4 times with a remainder of 389.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 2632 from 3021 to get 389.
Include the next digit (7) from the dividend after 389, then repeat: 3897 / 658

Step 5:
If we divide 3897 by 658, we get 5 and a remainder of 607.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtracting 3290 from 3897 leaves us with 607.
Take the next digit (8) from the dividend and append it to 607, then repeat: 6078 / 658

Advancing to step 6:
6078 divided by 658 is 9 with a remainder of 156.
Record the quotient 9 as the next digit in the result. 
Result so far: 459.0
If we take 5922 away from 6078, we end up with 156.
Take the next digit (8) from the dividend and append it to 156, then repeat: 1568 / 658

Going ahead to step 7:
658 goes into 1568 2 times with a remainder of 252.
Put 2 as the next digit of the answer. 
Result so far: 4592.0
Deduct 1316 from 1568 and we're left with 252.
Fetch the next digit (8) from the dividend, attach it to 252 and continue: 2528 / 658

On to step 8:
658 goes into 2528 3 times with a remainder of 554.
The number 3 becomes the next digit in our result. 
Result so far: 45923.0
The remainder is 554 after subtracting 1974 from 2528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Moving on to step 9:
658 goes into 5540 8 times with a remainder of 276.
Record the quotient 8 as the next digit in the result. 
Result so far: 45923.8
Subtracting 5264 from 5540 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 10:
658 can be fit into 2760 4 times, resulting in a remainder of 128.
Put 4 as the next digit of the answer. 
Result so far: 45923.84
If we subtract 2632 from 2760, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 11:
The number 658 fits into 1280 1 times, leaving a remainder of 622.
Use 1 as the next digit of our solution. 
Result so far: 45923.841
Subtract 658 from 1280 to get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Let's proceed to step 12:
The number 658 fits into 6220 9 times, leaving a remainder of 298.
Put 9 as the next digit of the answer. 
Result so far: 45923.8419
Subtracting 5922 from 6220 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 13:
When dividing 2980 by 658, we get 4 with a remainder of 348.
Write down 4 as next digit of the result. 
Result so far: 45923.84194
If we take 2632 away from 2980, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 14:
3480 divided by 658 is 5 with a remainder of 190.
Put 5 as the next digit of the answer. 
Result so far: 45923.841945
Subtract 3290 from 3480 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 15:
The number 658 fits into 1900 2 times, leaving a remainder of 584.
The next digit of our result is 2. 
Result so far: 45923.8419452
Subtracting 1316 from 1900 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

On to step 16:
The number 658 fits into 5840 8 times, leaving a remainder of 576.
The next digit of our result is 8. 
Result so far: 45923.84194528
Deduct 5264 from 5840 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

The quotient of the division is 45923.84194528, and the remainder is 5.76e-07.
