69674964 ÷ 258 
The aim is to understand the frequency of 258 in 69674964.

Step 1:
The number 258 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 258

Let's proceed to step 2:
The number 258 fits into 69 0 times, leaving a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Fetch the next digit (6) from the dividend, attach it to 69 and continue: 696 / 258

Going ahead to step 3:
696 divided by 258 is 2 with a remainder of 180.
The next digit of our result is 2. 
Result so far: 2.0
If we take 516 away from 696, we end up with 180.
Bring next digit (7) of the dividend behind the 180 and repeat the process: 1807 / 258

Moving on to step 4:
When dividing 1807 by 258, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we take 1806 away from 1807, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 258

Step 5:
The number 258 fits into 14 0 times, leaving a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 270.0
Subtracting 0 from 14 leaves us with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 258

Going ahead to step 6:
258 can be fit into 149 0 times, resulting in a remainder of 149.
Put 0 as the next digit of the answer. 
Result so far: 2700.0
The remainder is 149 after subtracting 0 from 149.
Append the next digit (6) from the dividend to 149 and continue with: 1496 / 258

Moving on to step 7:
1496 divided by 258 is 5 with a remainder of 206.
The number 5 becomes the next digit in our result. 
Result so far: 27005.0
Subtract 1290 from 1496 to get 206.
Take the next digit (4) from the dividend and append it to 206, then repeat: 2064 / 258

Advancing to step 8:
258 goes into 2064 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 270058.0
Deduct 2064 from 2064 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
The number 258 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 270058.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
The number 258 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 270058.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 270058.0, with a leftover of 0.0.
