We're dividing 506531 by 69 
The aim is to understand the frequency of 69 in 506531.

Step 1:
69 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 69

Let's proceed to step 2:
If we divide 50 by 69, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 69

On to step 3:
If we divide 506 by 69, we get 7 and a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 483 away from 506, we end up with 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 69

Going ahead to step 4:
69 can be fit into 235 3 times, resulting in a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 73.0
The remainder is 28 after subtracting 207 from 235.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 69

Let's proceed to step 5:
When dividing 283 by 69, we get 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 734.0
Deduct 276 from 283 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 69

Going ahead to step 6:
69 can be fit into 71 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 7341.0
The remainder is 2 after subtracting 69 from 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
20 divided by 69 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 7341.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
69 can be fit into 200 2 times, resulting in a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 7341.02
The remainder is 62 after subtracting 138 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 9:
69 goes into 620 8 times with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 7341.028
If we take 552 away from 620, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 10:
If we divide 680 by 69, we get 9 and a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 7341.0289
The remainder is 59 after subtracting 621 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 11:
69 can be fit into 590 8 times, resulting in a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 7341.02898
The remainder is 38 after subtracting 552 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
69 goes into 380 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 7341.028985
Subtracting 345 from 380 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 13:
If we divide 350 by 69, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 7341.0289855
If we take 345 away from 350, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 7341.0289855 with a remainder of 5e-08.
