We're dividing 7746366 by 258 
The aim is to understand the frequency of 258 in 7746366.

On to step 1:
258 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 258

Let's proceed to step 2:
When dividing 77 by 258, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Take the next digit (4) from the dividend and append it to 77, then repeat: 774 / 258

Advancing to step 3:
When dividing 774 by 258, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 774 from 774 leaves us with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 258

Let's proceed to step 4:
258 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 30.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 258

On to step 5:
If we divide 63 by 258, we get 0 and a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 300.0
Deduct 0 from 63 and we're left with 63.
Take the next digit (6) from the dividend and append it to 63, then repeat: 636 / 258

Step 6:
When dividing 636 by 258, we get 2 with a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 3002.0
The remainder is 120 after subtracting 516 from 636.
Bring next digit (6) of the dividend behind the 120 and repeat the process: 1206 / 258

Going ahead to step 7:
258 goes into 1206 4 times with a remainder of 174.
Put 4 as the next digit of the answer. 
Result so far: 30024.0
Subtracting 1032 from 1206 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 8:
If we divide 1740 by 258, we get 6 and a remainder of 192.
Write down 6 as next digit of the result. 
Result so far: 30024.6
Subtract 1548 from 1740 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 9:
When dividing 1920 by 258, we get 7 with a remainder of 114.
The number 7 becomes the next digit in our result. 
Result so far: 30024.67
If we take 1806 away from 1920, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 10:
When dividing 1140 by 258, we get 4 with a remainder of 108.
The number 4 becomes the next digit in our result. 
Result so far: 30024.674
Deduct 1032 from 1140 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 11:
When dividing 1080 by 258, we get 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 30024.6744
If we take 1032 away from 1080, we end up 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.

In conclusion, the division gives 30024.6744 with a balance of 0.00048.
