Let's divide 91486373 by 288
The aim is to understand the frequency of 288 in 91486373.

Step 1:
288 can be fit into 9 0 times, resulting in 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.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 288

Step 2:
The number 288 fits into 91 0 times, leaving a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Take the next digit (4) from the dividend and append it to 91, then repeat: 914 / 288

Step 3:
288 goes into 914 3 times with a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 864 from 914, we get 50.
Append the next digit (8) from the dividend to 50 and continue with: 508 / 288

Moving on to step 4:
508 divided by 288 is 1 with a remainder of 220.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtracting 288 from 508 leaves us with 220.
Include the next digit (6) from the dividend after 220, then repeat: 2206 / 288

Moving on to step 5:
288 can be fit into 2206 7 times, resulting in a remainder of 190.
Put 7 as the next digit of the answer. 
Result so far: 317.0
Subtract 2016 from 2206 to get 190.
Fetch the next digit (3) from the dividend, attach it to 190 and continue: 1903 / 288

Let's proceed to step 6:
288 can be fit into 1903 6 times, resulting in a remainder of 175.
Use 6 as the next digit of our solution. 
Result so far: 3176.0
If we subtract 1728 from 1903, we get 175.
Append the next digit (7) from the dividend to 175 and continue with: 1757 / 288

Step 7:
The number 288 fits into 1757 6 times, leaving a remainder of 29.
Put 6 as the next digit of the answer. 
Result so far: 31766.0
If we subtract 1728 from 1757, we get 29.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 288

Advancing to step 8:
293 divided by 288 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 317661.0
Subtracting 288 from 293 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
When dividing 50 by 288, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 317661.0
Subtracting 0 from 50 leaves us 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.

Step 10:
The number 288 fits into 500 1 times, leaving a remainder of 212.
The next digit of our result is 1. 
Result so far: 317661.01
Subtract 288 from 500 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 11:
288 goes into 2120 7 times with a remainder of 104.
The next digit of our result is 7. 
Result so far: 317661.017
Subtract 2016 from 2120 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 12:
If we divide 1040 by 288, we get 3 and a remainder of 176.
Put 3 as the next digit of the answer. 
Result so far: 317661.0173
If we take 864 away from 1040, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 13:
The number 288 fits into 1760 6 times, leaving a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 317661.01736
If we take 1728 away from 1760, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
288 can be fit into 320 1 times, resulting in a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 317661.017361
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 15:
The number 288 fits into 320 1 times, leaving a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 317661.0173611
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 317661.0173611 with a remainder of 3.2e-07.
