We divide 86852459 by 263
The aim is to understand the frequency of 263 in 86852459.

On to step 1:
If we divide 8 by 263, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 263

Step 2:
263 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Append the next digit (8) from the dividend to 86 and continue with: 868 / 263

On to step 3:
263 goes into 868 3 times with a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 789 from 868 to get 79.
Take the next digit (5) from the dividend and append it to 79, then repeat: 795 / 263

Moving on to step 4:
When dividing 795 by 263, we get 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 33.0
Subtract 789 from 795 to get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 263

On to step 5:
When dividing 62 by 263, we get 0 with a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 330.0
Subtracting 0 from 62 leaves us with 62.
Append the next digit (4) from the dividend to 62 and continue with: 624 / 263

Going ahead to step 6:
624 divided by 263 is 2 with a remainder of 98.
Record the quotient 2 as the next digit in the result. 
Result so far: 3302.0
If we take 526 away from 624, we end up with 98.
Take the next digit (5) from the dividend and append it to 98, then repeat: 985 / 263

Moving on to step 7:
985 divided by 263 is 3 with a remainder of 196.
Put 3 as the next digit of the answer. 
Result so far: 33023.0
The remainder is 196 after subtracting 789 from 985.
Take the next digit (9) from the dividend and append it to 196, then repeat: 1969 / 263

Going ahead to step 8:
263 can be fit into 1969 7 times, resulting in a remainder of 128.
The next digit of our result is 7. 
Result so far: 330237.0
Deduct 1841 from 1969 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 9:
263 goes into 1280 4 times with a remainder of 228.
Write down 4 as next digit of the result. 
Result so far: 330237.4
The remainder is 228 after subtracting 1052 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 10:
If we divide 2280 by 263, we get 8 and a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 330237.48
If we take 2104 away from 2280, 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.

Let's proceed to step 11:
When dividing 1760 by 263, we get 6 with a remainder of 182.
Write down 6 as next digit of the result. 
Result so far: 330237.486
If we subtract 1578 from 1760, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 12:
When dividing 1820 by 263, we get 6 with a remainder of 242.
Write down 6 as next digit of the result. 
Result so far: 330237.4866
If we subtract 1578 from 1820, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

After the division, we end up with 330237.4866 and a remainder of 0.00242.
