We look at the division of 26443673 by 258 
The aim is to understand the frequency of 258 in 26443673.

On to step 1:
2 divided by 258 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 258

Step 2:
26 divided by 258 is 0 with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 258

Moving on to step 3:
The number 258 fits into 264 1 times, leaving a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 258 from 264, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 258

Moving on to step 4:
When dividing 64 by 258, we get 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (3) from the dividend, attach it to 64 and continue: 643 / 258

On to step 5:
When dividing 643 by 258, we get 2 with a remainder of 127.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we take 516 away from 643, we end up with 127.
Include the next digit (6) from the dividend after 127, then repeat: 1276 / 258

Advancing to step 6:
1276 divided by 258 is 4 with a remainder of 244.
Write down 4 as next digit of the result. 
Result so far: 1024.0
If we subtract 1032 from 1276, we get 244.
Include the next digit (7) from the dividend after 244, then repeat: 2447 / 258

Let's proceed to step 7:
The number 258 fits into 2447 9 times, leaving a remainder of 125.
Record the quotient 9 as the next digit in the result. 
Result so far: 10249.0
The remainder is 125 after subtracting 2322 from 2447.
Bring next digit (3) of the dividend behind the 125 and repeat the process: 1253 / 258

Moving on to step 8:
When dividing 1253 by 258, we get 4 with a remainder of 221.
Record the quotient 4 as the next digit in the result. 
Result so far: 102494.0
If we subtract 1032 from 1253, we get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 9:
The number 258 fits into 2210 8 times, leaving a remainder of 146.
Write down 8 as next digit of the result. 
Result so far: 102494.8
Subtracting 2064 from 2210 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 10:
258 can be fit into 1460 5 times, resulting in a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 102494.85
Subtracting 1290 from 1460 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 11:
1700 divided by 258 is 6 with a remainder of 152.
Put 6 as the next digit of the answer. 
Result so far: 102494.856
If we subtract 1548 from 1700, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 12:
When dividing 1520 by 258, we get 5 with a remainder of 230.
The next digit of our result is 5. 
Result so far: 102494.8565
Deduct 1290 from 1520 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 13:
258 can be fit into 2300 8 times, resulting in a remainder of 236.
The next digit of our result is 8. 
Result so far: 102494.85658
Subtracting 2064 from 2300 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 14:
If we divide 2360 by 258, we get 9 and a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 102494.856589
Subtracting 2322 from 2360 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 15:
258 goes into 380 1 times with a remainder of 122.
Record the quotient 1 as the next digit in the result. 
Result so far: 102494.8565891
Deduct 258 from 380 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 16:
258 goes into 1220 4 times with a remainder of 188.
Write down 4 as next digit of the result. 
Result so far: 102494.85658914
If we take 1032 away from 1220, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

In conclusion, the division gives 102494.85658914 with a balance of 1.88e-07.
