We look at the division of 91163173 by 160 
The aim is to understand the frequency of 160 in 91163173.

On to step 1:
160 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 160

Going ahead to step 2:
If we divide 91 by 160, we get 0 and a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Include the next digit (1) from the dividend after 91, then repeat: 911 / 160

On to step 3:
If we divide 911 by 160, we get 5 and a remainder of 111.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 800 from 911 leaves us with 111.
Append the next digit (6) from the dividend to 111 and continue with: 1116 / 160

Moving on to step 4:
160 goes into 1116 6 times with a remainder of 156.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Subtract 960 from 1116 to get 156.
Bring next digit (3) of the dividend behind the 156 and repeat the process: 1563 / 160

Moving on to step 5:
When dividing 1563 by 160, we get 9 with a remainder of 123.
Put 9 as the next digit of the answer. 
Result so far: 569.0
The remainder is 123 after subtracting 1440 from 1563.
Fetch the next digit (1) from the dividend, attach it to 123 and continue: 1231 / 160

Going ahead to step 6:
The number 160 fits into 1231 7 times, leaving a remainder of 111.
Use 7 as the next digit of our solution. 
Result so far: 5697.0
If we subtract 1120 from 1231, we get 111.
Bring next digit (7) of the dividend behind the 111 and repeat the process: 1117 / 160

On to step 7:
1117 divided by 160 is 6 with a remainder of 157.
Use 6 as the next digit of our solution. 
Result so far: 56976.0
If we take 960 away from 1117, we end up with 157.
Bring next digit (3) of the dividend behind the 157 and repeat the process: 1573 / 160

Advancing to step 8:
160 goes into 1573 9 times with a remainder of 133.
Write down 9 as next digit of the result. 
Result so far: 569769.0
If we take 1440 away from 1573, we end up with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 9:
The number 160 fits into 1330 8 times, leaving a remainder of 50.
The next digit of our result is 8. 
Result so far: 569769.8
Subtract 1280 from 1330 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
When dividing 500 by 160, we get 3 with a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 569769.83
Subtract 480 from 500 to get 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:
When dividing 200 by 160, we get 1 with a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 569769.831
Subtracting 160 from 200 leaves us 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:
The number 160 fits into 400 2 times, leaving a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 569769.8312
If we take 320 away from 400, we end up 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.

On to step 13:
160 goes into 800 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 569769.83125
Subtract 800 from 800 to 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.

Advancing to step 14:
160 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 569769.83125
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.

Moving on to step 15:
160 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 569769.83125
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.

After the division, we end up with 569769.83125 and a remainder of 0.0.
