We divide 521366 by 69
The aim is to understand the frequency of 69 in 521366.

Step 1:
The number 69 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 69

Step 2:
If we divide 52 by 69, we get 0 and a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Grab the next digit (1) from the dividend, add it to 52, then carry on: 521 / 69

Step 3:
If we divide 521 by 69, we get 7 and a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 483 from 521 to get 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 69

Going ahead to step 4:
The number 69 fits into 383 5 times, leaving a remainder of 38.
The next digit of our result is 5. 
Result so far: 75.0
Subtracting 345 from 383 leaves us with 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 69

Advancing to step 5:
The number 69 fits into 386 5 times, leaving a remainder of 41.
The number 5 becomes the next digit in our result. 
Result so far: 755.0
The remainder is 41 after subtracting 345 from 386.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 69

Let's proceed to step 6:
416 divided by 69 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 7556.0
If we subtract 414 from 416, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
69 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 7556.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
If we divide 200 by 69, we get 2 and a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 7556.02
Deduct 138 from 200 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 9:
620 divided by 69 is 8 with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 7556.028
Subtract 552 from 620 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
69 goes into 680 9 times with a remainder of 59.
The next digit of our result is 9. 
Result so far: 7556.0289
If we subtract 621 from 680, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 11:
If we divide 590 by 69, we get 8 and a remainder of 38.
The next digit of our result is 8. 
Result so far: 7556.02898
If we take 552 away from 590, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
When dividing 380 by 69, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 7556.028985
If we take 345 away from 380, we end up 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.

Let's proceed to step 13:
350 divided by 69 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 7556.0289855
Deduct 345 from 350 and we're left 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.

After the division, we end up with 7556.0289855 and a remainder of 5e-08.
