We look at the division of 77373425 by 160 
The aim is to understand the frequency of 160 in 77373425.

Advancing to step 1:
160 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 160

Moving on to step 2:
160 goes into 77 0 times with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (3) from the dividend to 77 and continue with: 773 / 160

Step 3:
If we divide 773 by 160, we get 4 and a remainder of 133.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 133 after subtracting 640 from 773.
Include the next digit (7) from the dividend after 133, then repeat: 1337 / 160

Let's proceed to step 4:
160 goes into 1337 8 times with a remainder of 57.
Write down 8 as next digit of the result. 
Result so far: 48.0
The remainder is 57 after subtracting 1280 from 1337.
Append the next digit (3) from the dividend to 57 and continue with: 573 / 160

Advancing to step 5:
160 goes into 573 3 times with a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 483.0
If we subtract 480 from 573, we get 93.
Include the next digit (4) from the dividend after 93, then repeat: 934 / 160

Moving on to step 6:
934 divided by 160 is 5 with a remainder of 134.
Use 5 as the next digit of our solution. 
Result so far: 4835.0
Subtract 800 from 934 to get 134.
Append the next digit (2) from the dividend to 134 and continue with: 1342 / 160

Moving on to step 7:
160 goes into 1342 8 times with a remainder of 62.
The next digit of our result is 8. 
Result so far: 48358.0
If we subtract 1280 from 1342, we get 62.
Grab the next digit (5) from the dividend, add it to 62, then carry on: 625 / 160

Moving on to step 8:
When dividing 625 by 160, we get 3 with a remainder of 145.
Record the quotient 3 as the next digit in the result. 
Result so far: 483583.0
If we subtract 480 from 625, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 9:
When dividing 1450 by 160, we get 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 483583.9
If we subtract 1440 from 1450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
The number 160 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 483583.9
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
1000 divided by 160 is 6 with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 483583.906
Deduct 960 from 1000 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
400 divided by 160 is 2 with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 483583.9062
Subtract 320 from 400 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
800 divided by 160 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 483583.90625
If we subtract 800 from 800, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 14:
If we divide 0 by 160, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 483583.90625
If we take 0 away from 0, 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.

Going ahead to step 15:
160 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 483583.90625
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.

Our division results in 483583.90625 with a remaining 0.0.
