74164126 ÷ 258 
The aim is to understand the frequency of 258 in 74164126.

Going ahead to step 1:
If we divide 7 by 258, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 258

Advancing to step 2:
258 can be fit into 74 0 times, resulting in a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Bring next digit (1) of the dividend behind the 74 and repeat the process: 741 / 258

Let's proceed to step 3:
741 divided by 258 is 2 with a remainder of 225.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 516 away from 741, we end up with 225.
Grab the next digit (6) from the dividend, add it to 225, then carry on: 2256 / 258

Step 4:
If we divide 2256 by 258, we get 8 and a remainder of 192.
The next digit of our result is 8. 
Result so far: 28.0
Subtracting 2064 from 2256 leaves us with 192.
Bring next digit (4) of the dividend behind the 192 and repeat the process: 1924 / 258

Step 5:
When dividing 1924 by 258, we get 7 with a remainder of 118.
The number 7 becomes the next digit in our result. 
Result so far: 287.0
Subtract 1806 from 1924 to get 118.
Fetch the next digit (1) from the dividend, attach it to 118 and continue: 1181 / 258

Moving on to step 6:
The number 258 fits into 1181 4 times, leaving a remainder of 149.
The number 4 becomes the next digit in our result. 
Result so far: 2874.0
If we subtract 1032 from 1181, we get 149.
Append the next digit (2) from the dividend to 149 and continue with: 1492 / 258

Let's proceed to step 7:
1492 divided by 258 is 5 with a remainder of 202.
The next digit of our result is 5. 
Result so far: 28745.0
If we take 1290 away from 1492, we end up with 202.
Take the next digit (6) from the dividend and append it to 202, then repeat: 2026 / 258

Advancing to step 8:
2026 divided by 258 is 7 with a remainder of 220.
The next digit of our result is 7. 
Result so far: 287457.0
If we subtract 1806 from 2026, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 9:
The number 258 fits into 2200 8 times, leaving a remainder of 136.
Record the quotient 8 as the next digit in the result. 
Result so far: 287457.8
Deduct 2064 from 2200 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 10:
258 goes into 1360 5 times with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 287457.85
Deduct 1290 from 1360 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
258 goes into 700 2 times with a remainder of 184.
Record the quotient 2 as the next digit in the result. 
Result so far: 287457.852
Deduct 516 from 700 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 12:
1840 divided by 258 is 7 with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 287457.8527
If we take 1806 away from 1840, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 13:
258 can be fit into 340 1 times, resulting in a remainder of 82.
The next digit of our result is 1. 
Result so far: 287457.85271
If we subtract 258 from 340, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 14:
If we divide 820 by 258, we get 3 and a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 287457.852713
Subtracting 774 from 820 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 15:
If we divide 460 by 258, we get 1 and a remainder of 202.
Use 1 as the next digit of our solution. 
Result so far: 287457.8527131
If we take 258 away from 460, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 16:
2020 divided by 258 is 7 with a remainder of 214.
Write down 7 as next digit of the result. 
Result so far: 287457.85271317
If we take 1806 away from 2020, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

After the division, we end up with 287457.85271317 and a remainder of 2.14e-07.
