We're dividing 152590 by 69 
The aim is to understand the frequency of 69 in 152590.

Let's proceed to step 1:
69 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 69

On to step 2:
69 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 69

On to step 3:
If we divide 152 by 69, we get 2 and a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 138 from 152, we get 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 69

Moving on to step 4:
69 goes into 145 2 times with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 138 from 145 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 69

Let's proceed to step 5:
If we divide 79 by 69, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 221.0
Deduct 69 from 79 and we're left with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 69

Step 6:
69 goes into 100 1 times with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 2211.0
Subtract 69 from 100 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
69 can be fit into 310 4 times, resulting in a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 2211.4
If we subtract 276 from 310, we get 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 8:
340 divided by 69 is 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 2211.44
The remainder is 64 after subtracting 276 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 2211.44 with a remainder of 0.064.
