We're dividing 33118997 by 258 
The aim is to understand the frequency of 258 in 33118997.

Let's proceed to step 1:
The number 258 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 258

Let's proceed to step 2:
258 goes into 33 0 times with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 258

Going ahead to step 3:
331 divided by 258 is 1 with a remainder of 73.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 258 from 331 and we're left with 73.
Bring next digit (1) of the dividend behind the 73 and repeat the process: 731 / 258

Advancing to step 4:
If we divide 731 by 258, we get 2 and a remainder of 215.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 516 from 731 leaves us with 215.
Grab the next digit (8) from the dividend, add it to 215, then carry on: 2158 / 258

Step 5:
258 goes into 2158 8 times with a remainder of 94.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
The remainder is 94 after subtracting 2064 from 2158.
Include the next digit (9) from the dividend after 94, then repeat: 949 / 258

Let's proceed to step 6:
258 goes into 949 3 times with a remainder of 175.
Write down 3 as next digit of the result. 
Result so far: 1283.0
If we subtract 774 from 949, we get 175.
Append the next digit (9) from the dividend to 175 and continue with: 1759 / 258

Step 7:
If we divide 1759 by 258, we get 6 and a remainder of 211.
Put 6 as the next digit of the answer. 
Result so far: 12836.0
If we take 1548 away from 1759, we end up with 211.
Include the next digit (7) from the dividend after 211, then repeat: 2117 / 258

Advancing to step 8:
258 can be fit into 2117 8 times, resulting in a remainder of 53.
Use 8 as the next digit of our solution. 
Result so far: 128368.0
If we subtract 2064 from 2117, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
258 goes into 530 2 times with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 128368.2
If we subtract 516 from 530, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
The number 258 fits into 140 0 times, leaving a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 128368.2
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
If we divide 1400 by 258, we get 5 and a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 128368.205
Subtracting 1290 from 1400 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 12:
258 goes into 1100 4 times with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 128368.2054
The remainder is 68 after subtracting 1032 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 13:
When dividing 680 by 258, we get 2 with a remainder of 164.
Use 2 as the next digit of our solution. 
Result so far: 128368.20542
If we subtract 516 from 680, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 14:
If we divide 1640 by 258, we get 6 and a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 128368.205426
If we subtract 1548 from 1640, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 15:
The number 258 fits into 920 3 times, leaving a remainder of 146.
The number 3 becomes the next digit in our result. 
Result so far: 128368.2054263
If we subtract 774 from 920, we 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.

Advancing to step 16:
258 can be fit into 1460 5 times, resulting in a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 128368.20542635
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.

The final result is 128368.20542635 with a remainder of 1.7e-07.
