We're dividing 570226 by 69 
The aim is to understand the frequency of 69 in 570226.

Going ahead to step 1:
69 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 69

On to step 2:
If we divide 57 by 69, we get 0 and a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Take the next digit (0) from the dividend and append it to 57, then repeat: 570 / 69

Advancing to step 3:
570 divided by 69 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 552 away from 570, we end up with 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 69

Going ahead to step 4:
182 divided by 69 is 2 with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 82.0
Subtract 138 from 182 to get 44.
Grab the next digit (2) from the dividend, add it to 44, then carry on: 442 / 69

Let's proceed to step 5:
442 divided by 69 is 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 826.0
If we subtract 414 from 442, we get 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 69

Step 6:
69 can be fit into 286 4 times, resulting in a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 8264.0
Deduct 276 from 286 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
When dividing 100 by 69, we get 1 with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 8264.1
Deduct 69 from 100 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
If we divide 310 by 69, we get 4 and a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 8264.14
Subtract 276 from 310 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
When dividing 340 by 69, we get 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 8264.144
Subtracting 276 from 340 leaves us 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.

Our division results in 8264.144 with a remaining 0.0064.
