399889 divided by 69 
The aim is to understand the frequency of 69 in 399889.

Advancing to step 1:
69 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 69

Let's proceed to step 2:
When dividing 39 by 69, we get 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 69

Step 3:
The number 69 fits into 399 5 times, leaving a remainder of 54.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 345 from 399, we get 54.
Append the next digit (8) from the dividend to 54 and continue with: 548 / 69

Moving on to step 4:
69 goes into 548 7 times with a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
If we take 483 away from 548, we end up with 65.
Append the next digit (8) from the dividend to 65 and continue with: 658 / 69

Step 5:
If we divide 658 by 69, we get 9 and a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 579.0
If we subtract 621 from 658, we get 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 69

On to step 6:
379 divided by 69 is 5 with a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 5795.0
The remainder is 34 after subtracting 345 from 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 7:
69 can be fit into 340 4 times, resulting in a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 5795.4
If we take 276 away from 340, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 8:
When dividing 640 by 69, we get 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 5795.49
If we take 621 away from 640, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 9:
69 goes into 190 2 times with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 5795.492
Subtract 138 from 190 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
When dividing 520 by 69, we get 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 5795.4927
The remainder is 37 after subtracting 483 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
69 goes into 370 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 5795.49275
The remainder is 25 after subtracting 345 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
69 goes into 250 3 times with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 5795.492753
If we take 207 away from 250, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 13:
The number 69 fits into 430 6 times, leaving a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 5795.4927536
If we take 414 away from 430, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
If we divide 160 by 69, we get 2 and a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 5795.49275362
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 5795.49275362 with a remainder of 2.2e-08.
