We're dividing 8367882 by 258 
The aim is to understand the frequency of 258 in 8367882.

On to step 1:
258 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 258

Going ahead to step 2:
83 divided by 258 is 0 with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Fetch the next digit (6) from the dividend, attach it to 83 and continue: 836 / 258

Let's proceed to step 3:
When dividing 836 by 258, we get 3 with a remainder of 62.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 774 from 836, we get 62.
Fetch the next digit (7) from the dividend, attach it to 62 and continue: 627 / 258

Moving on to step 4:
258 can be fit into 627 2 times, resulting in a remainder of 111.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtract 516 from 627 to get 111.
Fetch the next digit (8) from the dividend, attach it to 111 and continue: 1118 / 258

Let's proceed to step 5:
258 goes into 1118 4 times with a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 324.0
If we take 1032 away from 1118, we end up with 86.
Append the next digit (8) from the dividend to 86 and continue with: 868 / 258

Moving on to step 6:
868 divided by 258 is 3 with a remainder of 94.
Put 3 as the next digit of the answer. 
Result so far: 3243.0
Subtract 774 from 868 to get 94.
Grab the next digit (2) from the dividend, add it to 94, then carry on: 942 / 258

Let's proceed to step 7:
When dividing 942 by 258, we get 3 with a remainder of 168.
Write down 3 as next digit of the result. 
Result so far: 32433.0
Subtracting 774 from 942 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 8:
The number 258 fits into 1680 6 times, leaving a remainder of 132.
Put 6 as the next digit of the answer. 
Result so far: 32433.6
Subtract 1548 from 1680 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 9:
If we divide 1320 by 258, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 32433.65
The remainder is 30 after subtracting 1290 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
If we divide 300 by 258, we get 1 and a remainder of 42.
The next digit of our result is 1. 
Result so far: 32433.651
If we take 258 away from 300, we end up 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 11:
258 can be fit into 420 1 times, resulting in a remainder of 162.
The next digit of our result is 1. 
Result so far: 32433.6511
Subtract 258 from 420 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

After the division, we end up with 32433.6511 and a remainder of 0.00162.
