51864309 ÷ 160 
The aim is to understand the frequency of 160 in 51864309.

Step 1:
160 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 160

Let's proceed to step 2:
If we divide 51 by 160, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (8) of the dividend behind the 51 and repeat the process: 518 / 160

On to step 3:
160 goes into 518 3 times with a remainder of 38.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 480 from 518, we get 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 160

Moving on to step 4:
If we divide 386 by 160, we get 2 and a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 32.0
If we subtract 320 from 386, we get 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 160

On to step 5:
664 divided by 160 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 324.0
The remainder is 24 after subtracting 640 from 664.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 160

Step 6:
When dividing 243 by 160, we get 1 with a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 3241.0
Subtracting 160 from 243 leaves us with 83.
Include the next digit (0) from the dividend after 83, then repeat: 830 / 160

Going ahead to step 7:
160 can be fit into 830 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 32415.0
Subtract 800 from 830 to get 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 160

On to step 8:
If we divide 309 by 160, we get 1 and a remainder of 149.
The number 1 becomes the next digit in our result. 
Result so far: 324151.0
Subtracting 160 from 309 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Going ahead to step 9:
The number 160 fits into 1490 9 times, leaving a remainder of 50.
The number 9 becomes the next digit in our result. 
Result so far: 324151.9
If we take 1440 away from 1490, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
When dividing 500 by 160, we get 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 324151.93
Deduct 480 from 500 and we're left 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.

Step 11:
The number 160 fits into 200 1 times, leaving a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 324151.931
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.

Moving on to step 12:
When dividing 400 by 160, we get 2 with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 324151.9312
Deduct 320 from 400 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
160 goes into 800 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 324151.93125
Subtracting 800 from 800 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:
160 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 324151.93125
Deduct 0 from 0 and we're left 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.

Let's proceed to step 15:
160 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 324151.93125
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.

After the division, we end up with 324151.93125 and a remainder of 0.0.
