We look at the division of 721827 by 69 
The aim is to understand the frequency of 69 in 721827.

Advancing to step 1:
If we divide 7 by 69, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 69

Advancing to step 2:
If we divide 72 by 69, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 69 away from 72, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 69

Going ahead to step 3:
The number 69 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 31, we end up with 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 69

On to step 4:
318 divided by 69 is 4 with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 104.0
If we take 276 away from 318, we end up with 42.
Append the next digit (2) from the dividend to 42 and continue with: 422 / 69

Going ahead to step 5:
69 can be fit into 422 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 1046.0
If we subtract 414 from 422, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 69

Advancing to step 6:
The number 69 fits into 87 1 times, leaving a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 10461.0
The remainder is 18 after subtracting 69 from 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
The number 69 fits into 180 2 times, leaving a remainder of 42.
The next digit of our result is 2. 
Result so far: 10461.2
Subtract 138 from 180 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
The number 69 fits into 420 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 10461.26
Deduct 414 from 420 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
69 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10461.26
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
The number 69 fits into 600 8 times, leaving a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 10461.2608
Deduct 552 from 600 and we're left 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.

Moving on to step 11:
69 can be fit into 480 6 times, resulting in a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 10461.26086
The remainder is 66 after subtracting 414 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 12:
69 can be fit into 660 9 times, resulting in a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 10461.260869
If we take 621 away from 660, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 13:
When dividing 390 by 69, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 10461.2608695
The remainder is 45 after subtracting 345 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
When dividing 450 by 69, we get 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 10461.26086956
The remainder is 36 after subtracting 414 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 10461.26086956, and the remainder is 3.6e-08.
