30690470 ÷ 553 
The aim is to understand the frequency of 553 in 30690470.

Moving on to step 1:
553 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 553

Let's proceed to step 2:
553 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 553

Advancing to step 3:
If we divide 306 by 553, we get 0 and a remainder of 306.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 306, we end up with 306.
Take the next digit (9) from the dividend and append it to 306, then repeat: 3069 / 553

Advancing to step 4:
The number 553 fits into 3069 5 times, leaving a remainder of 304.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 2765 away from 3069, we end up with 304.
Include the next digit (0) from the dividend after 304, then repeat: 3040 / 553

Advancing to step 5:
553 can be fit into 3040 5 times, resulting in a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 55.0
If we subtract 2765 from 3040, we get 275.
Take the next digit (4) from the dividend and append it to 275, then repeat: 2754 / 553

Step 6:
The number 553 fits into 2754 4 times, leaving a remainder of 542.
The next digit of our result is 4. 
Result so far: 554.0
If we take 2212 away from 2754, we end up with 542.
Append the next digit (7) from the dividend to 542 and continue with: 5427 / 553

Let's proceed to step 7:
5427 divided by 553 is 9 with a remainder of 450.
The next digit of our result is 9. 
Result so far: 5549.0
If we take 4977 away from 5427, we end up with 450.
Include the next digit (0) from the dividend after 450, then repeat: 4500 / 553

Let's proceed to step 8:
If we divide 4500 by 553, we get 8 and a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 55498.0
Subtract 4424 from 4500 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 9:
553 goes into 760 1 times with a remainder of 207.
Put 1 as the next digit of the answer. 
Result so far: 55498.1
Deduct 553 from 760 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Step 10:
When dividing 2070 by 553, we get 3 with a remainder of 411.
Record the quotient 3 as the next digit in the result. 
Result so far: 55498.13
Subtract 1659 from 2070 to get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Advancing to step 11:
The number 553 fits into 4110 7 times, leaving a remainder of 239.
Record the quotient 7 as the next digit in the result. 
Result so far: 55498.137
Subtract 3871 from 4110 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

On to step 12:
If we divide 2390 by 553, we get 4 and a remainder of 178.
Put 4 as the next digit of the answer. 
Result so far: 55498.1374
Subtract 2212 from 2390 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 13:
553 goes into 1780 3 times with a remainder of 121.
Write down 3 as next digit of the result. 
Result so far: 55498.13743
If we take 1659 away from 1780, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 14:
If we divide 1210 by 553, we get 2 and a remainder of 104.
The number 2 becomes the next digit in our result. 
Result so far: 55498.137432
The remainder is 104 after subtracting 1106 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 15:
The number 553 fits into 1040 1 times, leaving a remainder of 487.
Write down 1 as next digit of the result. 
Result so far: 55498.1374321
Subtract 553 from 1040 to get 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Let's proceed to step 16:
If we divide 4870 by 553, we get 8 and a remainder of 446.
Put 8 as the next digit of the answer. 
Result so far: 55498.13743218
Subtracting 4424 from 4870 leaves us with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

The final result is 55498.13743218 with a remainder of 4.46e-07.
