73893211 ÷ 263 
The aim is to understand the frequency of 263 in 73893211.

Advancing to step 1:
7 divided by 263 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 263

Going ahead to step 2:
73 divided by 263 is 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 263

On to step 3:
If we divide 738 by 263, we get 2 and a remainder of 212.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 526 from 738 and we're left with 212.
Take the next digit (9) from the dividend and append it to 212, then repeat: 2129 / 263

Going ahead to step 4:
When dividing 2129 by 263, we get 8 with a remainder of 25.
The next digit of our result is 8. 
Result so far: 28.0
If we take 2104 away from 2129, we end up with 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 263

Let's proceed to step 5:
When dividing 253 by 263, we get 0 with a remainder of 253.
The number 0 becomes the next digit in our result. 
Result so far: 280.0
Subtract 0 from 253 to get 253.
Include the next digit (2) from the dividend after 253, then repeat: 2532 / 263

Going ahead to step 6:
263 can be fit into 2532 9 times, resulting in a remainder of 165.
Use 9 as the next digit of our solution. 
Result so far: 2809.0
The remainder is 165 after subtracting 2367 from 2532.
Take the next digit (1) from the dividend and append it to 165, then repeat: 1651 / 263

Advancing to step 7:
If we divide 1651 by 263, we get 6 and a remainder of 73.
The number 6 becomes the next digit in our result. 
Result so far: 28096.0
Subtract 1578 from 1651 to get 73.
Append the next digit (1) from the dividend to 73 and continue with: 731 / 263

Step 8:
731 divided by 263 is 2 with a remainder of 205.
The number 2 becomes the next digit in our result. 
Result so far: 280962.0
Subtracting 526 from 731 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 9:
263 can be fit into 2050 7 times, resulting in a remainder of 209.
Record the quotient 7 as the next digit in the result. 
Result so far: 280962.7
Deduct 1841 from 2050 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 10:
263 can be fit into 2090 7 times, resulting in a remainder of 249.
Record the quotient 7 as the next digit in the result. 
Result so far: 280962.77
Subtract 1841 from 2090 to get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

In conclusion, the division gives 280962.77 with a balance of 0.249.
