We're dividing 70375845 by 258 
The aim is to understand the frequency of 258 in 70375845.

Going ahead to step 1:
If we divide 7 by 258, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 258

Advancing to step 2:
When dividing 70 by 258, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Bring next digit (3) of the dividend behind the 70 and repeat the process: 703 / 258

Let's proceed to step 3:
The number 258 fits into 703 2 times, leaving a remainder of 187.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 516 from 703, we get 187.
Append the next digit (7) from the dividend to 187 and continue with: 1877 / 258

Step 4:
258 goes into 1877 7 times with a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtract 1806 from 1877 to get 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 258

Step 5:
The number 258 fits into 715 2 times, leaving a remainder of 199.
The next digit of our result is 2. 
Result so far: 272.0
Subtract 516 from 715 to get 199.
Bring next digit (8) of the dividend behind the 199 and repeat the process: 1998 / 258

On to step 6:
258 can be fit into 1998 7 times, resulting in a remainder of 192.
Put 7 as the next digit of the answer. 
Result so far: 2727.0
If we subtract 1806 from 1998, we get 192.
Append the next digit (4) from the dividend to 192 and continue with: 1924 / 258

On to step 7:
1924 divided by 258 is 7 with a remainder of 118.
Record the quotient 7 as the next digit in the result. 
Result so far: 27277.0
Deduct 1806 from 1924 and we're left with 118.
Take the next digit (5) from the dividend and append it to 118, then repeat: 1185 / 258

Advancing to step 8:
When dividing 1185 by 258, we get 4 with a remainder of 153.
The number 4 becomes the next digit in our result. 
Result so far: 272774.0
The remainder is 153 after subtracting 1032 from 1185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 9:
When dividing 1530 by 258, we get 5 with a remainder of 240.
The number 5 becomes the next digit in our result. 
Result so far: 272774.5
Subtracting 1290 from 1530 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 10:
The number 258 fits into 2400 9 times, leaving a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 272774.59
If we subtract 2322 from 2400, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 11:
When dividing 780 by 258, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 272774.593
Subtract 774 from 780 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
The number 258 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 272774.593
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
600 divided by 258 is 2 with a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 272774.59302
If we take 516 away from 600, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 14:
840 divided by 258 is 3 with a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 272774.593023
The remainder is 66 after subtracting 774 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 15:
When dividing 660 by 258, we get 2 with a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 272774.5930232
The remainder is 144 after subtracting 516 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 16:
When dividing 1440 by 258, we get 5 with a remainder of 150.
The next digit of our result is 5. 
Result so far: 272774.59302325
Subtracting 1290 from 1440 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The quotient of the division is 272774.59302325, and the remainder is 1.5e-07.
