Let's divide 8239061 by 263
The aim is to understand the frequency of 263 in 8239061.

On to step 1:
8 divided by 263 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 263

On to step 2:
82 divided by 263 is 0 with a remainder of 82.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Append the next digit (3) from the dividend to 82 and continue with: 823 / 263

Let's proceed to step 3:
823 divided by 263 is 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 789 from 823, we get 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 263

Moving on to step 4:
263 goes into 349 1 times with a remainder of 86.
The next digit of our result is 1. 
Result so far: 31.0
If we subtract 263 from 349, we get 86.
Fetch the next digit (0) from the dividend, attach it to 86 and continue: 860 / 263

Let's proceed to step 5:
263 can be fit into 860 3 times, resulting in a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 313.0
Subtract 789 from 860 to get 71.
Fetch the next digit (6) from the dividend, attach it to 71 and continue: 716 / 263

Moving on to step 6:
When dividing 716 by 263, we get 2 with a remainder of 190.
Record the quotient 2 as the next digit in the result. 
Result so far: 3132.0
If we subtract 526 from 716, we get 190.
Append the next digit (1) from the dividend to 190 and continue with: 1901 / 263

Going ahead to step 7:
263 goes into 1901 7 times with a remainder of 60.
The next digit of our result is 7. 
Result so far: 31327.0
The remainder is 60 after subtracting 1841 from 1901.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
600 divided by 263 is 2 with a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 31327.2
Subtract 526 from 600 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 9:
263 goes into 740 2 times with a remainder of 214.
The number 2 becomes the next digit in our result. 
Result so far: 31327.22
The remainder is 214 after subtracting 526 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

After the division, we end up with 31327.22 and a remainder of 0.214.
