66344553 ÷ 163 
The aim is to understand the frequency of 163 in 66344553.

Moving on to step 1:
6 divided by 163 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 163

Step 2:
66 divided by 163 is 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 163

Advancing to step 3:
663 divided by 163 is 4 with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 11 after subtracting 652 from 663.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 163

Step 4:
163 can be fit into 114 0 times, resulting in a remainder of 114.
Put 0 as the next digit of the answer. 
Result so far: 40.0
If we take 0 away from 114, we end up with 114.
Include the next digit (4) from the dividend after 114, then repeat: 1144 / 163

On to step 5:
1144 divided by 163 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 407.0
Deduct 1141 from 1144 and we're left with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 163

Moving on to step 6:
163 can be fit into 35 0 times, resulting in a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 4070.0
The remainder is 35 after subtracting 0 from 35.
Take the next digit (5) from the dividend and append it to 35, then repeat: 355 / 163

On to step 7:
When dividing 355 by 163, we get 2 with a remainder of 29.
The next digit of our result is 2. 
Result so far: 40702.0
Subtracting 326 from 355 leaves us with 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 163

Advancing to step 8:
293 divided by 163 is 1 with a remainder of 130.
The number 1 becomes the next digit in our result. 
Result so far: 407021.0
Subtracting 163 from 293 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 9:
1300 divided by 163 is 7 with a remainder of 159.
Put 7 as the next digit of the answer. 
Result so far: 407021.7
Subtracting 1141 from 1300 leaves us with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 10:
163 can be fit into 1590 9 times, resulting in a remainder of 123.
Use 9 as the next digit of our solution. 
Result so far: 407021.79
The remainder is 123 after subtracting 1467 from 1590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Step 11:
The number 163 fits into 1230 7 times, leaving a remainder of 89.
The next digit of our result is 7. 
Result so far: 407021.797
If we subtract 1141 from 1230, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 12:
163 goes into 890 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 407021.7975
Deduct 815 from 890 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 13:
The number 163 fits into 750 4 times, leaving a remainder of 98.
The number 4 becomes the next digit in our result. 
Result so far: 407021.79754
If we take 652 away from 750, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 14:
If we divide 980 by 163, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 407021.797546
Subtracting 978 from 980 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 15:
If we divide 20 by 163, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 407021.797546
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 16:
163 can be fit into 200 1 times, resulting in a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 407021.79754601
Subtract 163 from 200 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

In conclusion, the division gives 407021.79754601 with a balance of 3.7e-08.
