Let's divide 66168116 by 258
The aim is to understand the frequency of 258 in 66168116.

Advancing to step 1:
When dividing 6 by 258, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 258

Let's proceed to step 2:
The number 258 fits into 66 0 times, leaving a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 258

Going ahead to step 3:
When dividing 661 by 258, we get 2 with a remainder of 145.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 516 away from 661, we end up with 145.
Grab the next digit (6) from the dividend, add it to 145, then carry on: 1456 / 258

Going ahead to step 4:
If we divide 1456 by 258, we get 5 and a remainder of 166.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 1290 away from 1456, we end up with 166.
Append the next digit (8) from the dividend to 166 and continue with: 1668 / 258

Advancing to step 5:
The number 258 fits into 1668 6 times, leaving a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 256.0
Deduct 1548 from 1668 and we're left with 120.
Grab the next digit (1) from the dividend, add it to 120, then carry on: 1201 / 258

On to step 6:
1201 divided by 258 is 4 with a remainder of 169.
The next digit of our result is 4. 
Result so far: 2564.0
Deduct 1032 from 1201 and we're left with 169.
Include the next digit (1) from the dividend after 169, then repeat: 1691 / 258

On to step 7:
If we divide 1691 by 258, we get 6 and a remainder of 143.
The next digit of our result is 6. 
Result so far: 25646.0
The remainder is 143 after subtracting 1548 from 1691.
Bring next digit (6) of the dividend behind the 143 and repeat the process: 1436 / 258

On to step 8:
1436 divided by 258 is 5 with a remainder of 146.
The next digit of our result is 5. 
Result so far: 256465.0
Subtract 1290 from 1436 to get 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 9:
258 can be fit into 1460 5 times, resulting in a remainder of 170.
The next digit of our result is 5. 
Result so far: 256465.5
Subtract 1290 from 1460 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 10:
The number 258 fits into 1700 6 times, leaving a remainder of 152.
Put 6 as the next digit of the answer. 
Result so far: 256465.56
Deduct 1548 from 1700 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 11:
The number 258 fits into 1520 5 times, leaving a remainder of 230.
The number 5 becomes the next digit in our result. 
Result so far: 256465.565
The remainder is 230 after subtracting 1290 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 12:
2300 divided by 258 is 8 with a remainder of 236.
Record the quotient 8 as the next digit in the result. 
Result so far: 256465.5658
If we take 2064 away from 2300, we end up 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.

On to step 13:
If we divide 2360 by 258, we get 9 and a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 256465.56589
If we take 2322 away from 2360, we end up 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 14:
If we divide 380 by 258, we get 1 and a remainder of 122.
Put 1 as the next digit of the answer. 
Result so far: 256465.565891
Subtracting 258 from 380 leaves us 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 15:
When dividing 1220 by 258, we get 4 with a remainder of 188.
The next digit of our result is 4. 
Result so far: 256465.5658914
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.

Step 16:
258 goes into 1880 7 times with a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 256465.56589147
Subtracting 1806 from 1880 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Our division results in 256465.56589147 with a remaining 7.4e-08.
