We look at the division of 21268333 by 658 
The aim is to understand the frequency of 658 in 21268333.

Moving on to step 1:
The number 658 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 658

Advancing to step 2:
658 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 658

Step 3:
The number 658 fits into 212 0 times, leaving a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 212 and we're left with 212.
Include the next digit (6) from the dividend after 212, then repeat: 2126 / 658

Step 4:
2126 divided by 658 is 3 with a remainder of 152.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 1974 from 2126, we get 152.
Append the next digit (8) from the dividend to 152 and continue with: 1528 / 658

Let's proceed to step 5:
1528 divided by 658 is 2 with a remainder of 212.
Write down 2 as next digit of the result. 
Result so far: 32.0
If we take 1316 away from 1528, we end up with 212.
Bring next digit (3) of the dividend behind the 212 and repeat the process: 2123 / 658

Advancing to step 6:
2123 divided by 658 is 3 with a remainder of 149.
Write down 3 as next digit of the result. 
Result so far: 323.0
The remainder is 149 after subtracting 1974 from 2123.
Fetch the next digit (3) from the dividend, attach it to 149 and continue: 1493 / 658

Let's proceed to step 7:
1493 divided by 658 is 2 with a remainder of 177.
Use 2 as the next digit of our solution. 
Result so far: 3232.0
The remainder is 177 after subtracting 1316 from 1493.
Take the next digit (3) from the dividend and append it to 177, then repeat: 1773 / 658

Going ahead to step 8:
658 goes into 1773 2 times with a remainder of 457.
The next digit of our result is 2. 
Result so far: 32322.0
The remainder is 457 after subtracting 1316 from 1773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Step 9:
If we divide 4570 by 658, we get 6 and a remainder of 622.
Use 6 as the next digit of our solution. 
Result so far: 32322.6
The remainder is 622 after subtracting 3948 from 4570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Step 10:
If we divide 6220 by 658, we get 9 and a remainder of 298.
The next digit of our result is 9. 
Result so far: 32322.69
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.

Step 11:
2980 divided by 658 is 4 with a remainder of 348.
Write down 4 as next digit of the result. 
Result so far: 32322.694
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.

Going ahead to step 12:
The number 658 fits into 3480 5 times, leaving a remainder of 190.
Put 5 as the next digit of the answer. 
Result so far: 32322.6945
Subtracting 3290 from 3480 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 13:
When dividing 1900 by 658, we get 2 with a remainder of 584.
The number 2 becomes the next digit in our result. 
Result so far: 32322.69452
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.

Let's proceed to step 14:
658 can be fit into 5840 8 times, resulting in a remainder of 576.
Use 8 as the next digit of our solution. 
Result so far: 32322.694528
Subtract 5264 from 5840 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Going ahead to step 15:
5760 divided by 658 is 8 with a remainder of 496.
The next digit of our result is 8. 
Result so far: 32322.6945288
The remainder is 496 after subtracting 5264 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

In conclusion, the division gives 32322.6945288 with a balance of 4.96e-06.
