We're dividing 40578 by 69 
The aim is to understand the frequency of 69 in 40578.

Let's proceed to step 1:
The number 69 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 69

Step 2:
40 divided by 69 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 69

Step 3:
69 goes into 405 5 times with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 345 from 405 and we're left with 60.
Append the next digit (7) from the dividend to 60 and continue with: 607 / 69

Advancing to step 4:
607 divided by 69 is 8 with a remainder of 55.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
If we take 552 away from 607, we end up with 55.
Include the next digit (8) from the dividend after 55, then repeat: 558 / 69

Going ahead to step 5:
558 divided by 69 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 588.0
Subtracting 552 from 558 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 6:
When dividing 60 by 69, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 588.0
Subtract 0 from 60 to get 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 7:
600 divided by 69 is 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 588.08
If we take 552 away from 600, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
When dividing 480 by 69, we get 6 with a remainder of 66.
The next digit of our result is 6. 
Result so far: 588.086
The remainder is 66 after subtracting 414 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 9:
69 goes into 660 9 times with a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 588.0869
Subtracting 621 from 660 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
390 divided by 69 is 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 588.08695
Deduct 345 from 390 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 11:
69 goes into 450 6 times with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 588.086956
Subtracting 414 from 450 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
69 can be fit into 360 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 588.0869565
Subtracting 345 from 360 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
When dividing 150 by 69, we get 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 588.08695652
Subtracting 138 from 150 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 588.08695652 and a remainder of 1.2e-08.
