We're dividing 126571 by 69 
The aim is to understand the frequency of 69 in 126571.

Let's proceed to step 1:
If we divide 1 by 69, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 69

On to step 2:
12 divided by 69 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 69

Moving on to step 3:
69 goes into 126 1 times with a remainder of 57.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 69 from 126 leaves us with 57.
Fetch the next digit (5) from the dividend, attach it to 57 and continue: 575 / 69

Moving on to step 4:
When dividing 575 by 69, we get 8 with a remainder of 23.
The next digit of our result is 8. 
Result so far: 18.0
If we take 552 away from 575, we end up with 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 69

Going ahead to step 5:
When dividing 237 by 69, we get 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 183.0
The remainder is 30 after subtracting 207 from 237.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 69

Let's proceed to step 6:
69 can be fit into 301 4 times, resulting in a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 1834.0
Subtracting 276 from 301 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
69 goes into 250 3 times with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 1834.3
Subtract 207 from 250 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 8:
430 divided by 69 is 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 1834.36
The remainder is 16 after subtracting 414 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
When dividing 160 by 69, we get 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 1834.362
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
If we divide 220 by 69, we get 3 and a remainder of 13.
The next digit of our result is 3. 
Result so far: 1834.3623
If we take 207 away from 220, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
69 can be fit into 130 1 times, resulting in a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 1834.36231
If we subtract 69 from 130, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 12:
610 divided by 69 is 8 with a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 1834.362318
Subtracting 552 from 610 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 13:
When dividing 580 by 69, we get 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 1834.3623188
If we take 552 away from 580, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 1834.3623188, and the remainder is 2.8e-07.
