We're dividing 903549 by 69 
The aim is to understand the frequency of 69 in 903549.

Step 1:
If we divide 9 by 69, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 69

Moving on to step 2:
When dividing 90 by 69, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 69 from 90 leaves us with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 69

On to step 3:
213 divided by 69 is 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 207 from 213 and we're left with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 69

Step 4:
69 goes into 65 0 times with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
Subtract 0 from 65 to get 65.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 69

Moving on to step 5:
When dividing 654 by 69, we get 9 with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 1309.0
Subtract 621 from 654 to get 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 69

Going ahead to step 6:
When dividing 339 by 69, we get 4 with a remainder of 63.
The number 4 becomes the next digit in our result. 
Result so far: 13094.0
If we take 276 away from 339, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 7:
The number 69 fits into 630 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 13094.9
If we take 621 away from 630, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
If we divide 90 by 69, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 13094.91
Deduct 69 from 90 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
210 divided by 69 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 13094.913
If we subtract 207 from 210, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
The number 69 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 13094.913
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
If we divide 300 by 69, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 13094.91304
Subtracting 276 from 300 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
If we divide 240 by 69, we get 3 and a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 13094.913043
Deduct 207 from 240 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 13:
69 goes into 330 4 times with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 13094.9130434
The remainder is 54 after subtracting 276 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 14:
If we divide 540 by 69, we get 7 and a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 13094.91304347
Subtract 483 from 540 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final result is 13094.91304347 with a remainder of 5.7e-08.
