We look at the division of 39484559 by 263 
The aim is to understand the frequency of 263 in 39484559.

Step 1:
3 divided by 263 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 263

Moving on to step 2:
The number 263 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 263

Let's proceed to step 3:
If we divide 394 by 263, we get 1 and a remainder of 131.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 131 after subtracting 263 from 394.
Take the next digit (8) from the dividend and append it to 131, then repeat: 1318 / 263

Advancing to step 4:
263 goes into 1318 5 times with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 3 after subtracting 1315 from 1318.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 263

Advancing to step 5:
263 goes into 34 0 times with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 150.0
The remainder is 34 after subtracting 0 from 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 263

Moving on to step 6:
When dividing 345 by 263, we get 1 with a remainder of 82.
The number 1 becomes the next digit in our result. 
Result so far: 1501.0
If we subtract 263 from 345, we get 82.
Bring next digit (5) of the dividend behind the 82 and repeat the process: 825 / 263

Going ahead to step 7:
If we divide 825 by 263, we get 3 and a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 15013.0
The remainder is 36 after subtracting 789 from 825.
Take the next digit (9) from the dividend and append it to 36, then repeat: 369 / 263

Going ahead to step 8:
369 divided by 263 is 1 with a remainder of 106.
The number 1 becomes the next digit in our result. 
Result so far: 150131.0
Deduct 263 from 369 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 9:
The number 263 fits into 1060 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 150131.4
Subtracting 1052 from 1060 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
263 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 150131.4
The remainder is 80 after subtracting 0 from 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 11:
263 can be fit into 800 3 times, resulting in a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 150131.403
The remainder is 11 after subtracting 789 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 12:
263 can be fit into 110 0 times, resulting in a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 150131.403
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 13:
When dividing 1100 by 263, we get 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 150131.40304
Deduct 1052 from 1100 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
The number 263 fits into 480 1 times, leaving a remainder of 217.
Use 1 as the next digit of our solution. 
Result so far: 150131.403041
Subtracting 263 from 480 leaves us with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 15:
263 goes into 2170 8 times with a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 150131.4030418
Subtract 2104 from 2170 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 16:
When dividing 660 by 263, we get 2 with a remainder of 134.
The number 2 becomes the next digit in our result. 
Result so far: 150131.40304182
If we take 526 away from 660, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Our division results in 150131.40304182 with a remaining 1.34e-07.
