405009 divided by 69 
The aim is to understand the frequency of 69 in 405009.

Moving on to step 1:
69 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 69

Advancing to step 2:
The number 69 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 69

Going ahead to step 3:
The number 69 fits into 405 5 times, leaving a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 345 from 405 to get 60.
Include the next digit (0) from the dividend after 60, then repeat: 600 / 69

Moving on to step 4:
600 divided by 69 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 58.0
Subtracting 552 from 600 leaves us with 48.
Grab the next digit (0) from the dividend, add it to 48, then carry on: 480 / 69

On to step 5:
The number 69 fits into 480 6 times, leaving a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 586.0
Deduct 414 from 480 and we're left with 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 69

Going ahead to step 6:
669 divided by 69 is 9 with a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 5869.0
Subtracting 621 from 669 leaves us 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 7:
If we divide 480 by 69, we get 6 and a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 5869.6
Subtracting 414 from 480 leaves us with 66.
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 8:
69 can be fit into 660 9 times, resulting in a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 5869.69
Subtract 621 from 660 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 9:
If we divide 390 by 69, we get 5 and a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 5869.695
Subtracting 345 from 390 leaves us 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.

Step 10:
69 can be fit into 450 6 times, resulting in a remainder of 36.
The next digit of our result is 6. 
Result so far: 5869.6956
If we subtract 414 from 450, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
If we divide 360 by 69, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 5869.69565
If we take 345 away from 360, we end up 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 12:
The number 69 fits into 150 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 5869.695652
Subtract 138 from 150 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
The number 69 fits into 120 1 times, leaving a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 5869.6956521
Subtracting 69 from 120 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 14:
69 can be fit into 510 7 times, resulting in a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 5869.69565217
Deduct 483 from 510 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The quotient of the division is 5869.69565217, and the remainder is 2.7e-08.
