We divide 18711864 by 263
The aim is to understand the frequency of 263 in 18711864.

Let's proceed to step 1:
If we divide 1 by 263, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 263

Going ahead to step 2:
The number 263 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 263

Let's proceed to step 3:
263 goes into 187 0 times with a remainder of 187.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 187 leaves us with 187.
Bring next digit (1) of the dividend behind the 187 and repeat the process: 1871 / 263

On to step 4:
263 goes into 1871 7 times with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 1841 from 1871 to get 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 263

Step 5:
When dividing 301 by 263, we get 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we subtract 263 from 301, we get 38.
Bring next digit (8) of the dividend behind the 38 and repeat the process: 388 / 263

Going ahead to step 6:
263 can be fit into 388 1 times, resulting in a remainder of 125.
The number 1 becomes the next digit in our result. 
Result so far: 711.0
If we take 263 away from 388, we end up with 125.
Grab the next digit (6) from the dividend, add it to 125, then carry on: 1256 / 263

Going ahead to step 7:
263 goes into 1256 4 times with a remainder of 204.
Write down 4 as next digit of the result. 
Result so far: 7114.0
If we take 1052 away from 1256, we end up with 204.
Include the next digit (4) from the dividend after 204, then repeat: 2044 / 263

Moving on to step 8:
When dividing 2044 by 263, we get 7 with a remainder of 203.
Use 7 as the next digit of our solution. 
Result so far: 71147.0
The remainder is 203 after subtracting 1841 from 2044.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Moving on to step 9:
If we divide 2030 by 263, we get 7 and a remainder of 189.
Use 7 as the next digit of our solution. 
Result so far: 71147.7
Subtract 1841 from 2030 to get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Going ahead to step 10:
The number 263 fits into 1890 7 times, leaving a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 71147.77
Deduct 1841 from 1890 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final result is 71147.77 with a remainder of 0.049.
