20233434 ÷ 258 
The aim is to understand the frequency of 258 in 20233434.

Moving on to step 1:
The number 258 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 258

Advancing to step 2:
When dividing 20 by 258, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 258

Let's proceed to step 3:
202 divided by 258 is 0 with a remainder of 202.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 202, we end up with 202.
Take the next digit (3) from the dividend and append it to 202, then repeat: 2023 / 258

Advancing to step 4:
If we divide 2023 by 258, we get 7 and a remainder of 217.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 1806 from 2023 to get 217.
Bring next digit (3) of the dividend behind the 217 and repeat the process: 2173 / 258

On to step 5:
258 goes into 2173 8 times with a remainder of 109.
Use 8 as the next digit of our solution. 
Result so far: 78.0
If we subtract 2064 from 2173, we get 109.
Bring next digit (4) of the dividend behind the 109 and repeat the process: 1094 / 258

Moving on to step 6:
If we divide 1094 by 258, we get 4 and a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 784.0
If we subtract 1032 from 1094, we get 62.
Include the next digit (3) from the dividend after 62, then repeat: 623 / 258

On to step 7:
258 can be fit into 623 2 times, resulting in a remainder of 107.
Write down 2 as next digit of the result. 
Result so far: 7842.0
Deduct 516 from 623 and we're left with 107.
Bring next digit (4) of the dividend behind the 107 and repeat the process: 1074 / 258

Moving on to step 8:
258 goes into 1074 4 times with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 78424.0
Deduct 1032 from 1074 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
The number 258 fits into 420 1 times, leaving a remainder of 162.
The next digit of our result is 1. 
Result so far: 78424.1
Subtracting 258 from 420 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 10:
The number 258 fits into 1620 6 times, leaving a remainder of 72.
The next digit of our result is 6. 
Result so far: 78424.16
The remainder is 72 after subtracting 1548 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 11:
258 can be fit into 720 2 times, resulting in a remainder of 204.
Write down 2 as next digit of the result. 
Result so far: 78424.162
If we subtract 516 from 720, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 12:
258 goes into 2040 7 times with a remainder of 234.
Write down 7 as next digit of the result. 
Result so far: 78424.1627
Deduct 1806 from 2040 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 13:
258 goes into 2340 9 times with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 78424.16279
Deduct 2322 from 2340 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
180 divided by 258 is 0 with a remainder of 180.
The next digit of our result is 0. 
Result so far: 78424.16279
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 15:
258 goes into 1800 6 times with a remainder of 252.
Record the quotient 6 as the next digit in the result. 
Result so far: 78424.1627906
The remainder is 252 after subtracting 1548 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 16:
258 goes into 2520 9 times with a remainder of 198.
Write down 9 as next digit of the result. 
Result so far: 78424.16279069
Deduct 2322 from 2520 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

The quotient of the division is 78424.16279069, and the remainder is 1.98e-07.
