We look at the division of 66305954 by 160 
The aim is to understand the frequency of 160 in 66305954.

Let's proceed to step 1:
6 divided by 160 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 160

Let's proceed to step 2:
When dividing 66 by 160, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 160

Advancing to step 3:
160 can be fit into 663 4 times, resulting in a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 640 from 663 leaves us with 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 160

Going ahead to step 4:
If we divide 230 by 160, we get 1 and a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
If we subtract 160 from 230, we get 70.
Bring next digit (5) of the dividend behind the 70 and repeat the process: 705 / 160

Advancing to step 5:
If we divide 705 by 160, we get 4 and a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 414.0
Deduct 640 from 705 and we're left with 65.
Take the next digit (9) from the dividend and append it to 65, then repeat: 659 / 160

On to step 6:
659 divided by 160 is 4 with a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 4144.0
Deduct 640 from 659 and we're left with 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 160

On to step 7:
160 goes into 195 1 times with a remainder of 35.
The next digit of our result is 1. 
Result so far: 41441.0
Deduct 160 from 195 and we're left with 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 160

Let's proceed to step 8:
354 divided by 160 is 2 with a remainder of 34.
The next digit of our result is 2. 
Result so far: 414412.0
Deduct 320 from 354 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
If we divide 340 by 160, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 414412.2
Subtracting 320 from 340 leaves us 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 10:
160 can be fit into 200 1 times, resulting in a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 414412.21
Subtract 160 from 200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
400 divided by 160 is 2 with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 414412.212
The remainder is 80 after subtracting 320 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
The number 160 fits into 800 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 414412.2125
If we take 800 away from 800, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
When dividing 0 by 160, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 414412.2125
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 14:
The number 160 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 414412.2125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 414412.2125 and a remainder of 0.0.
