We look at the division of 660336 by 70 
The aim is to understand the frequency of 70 in 660336.

Step 1:
When dividing 6 by 70, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 70

Step 2:
When dividing 66 by 70, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (0) from the dividend and append it to 66, then repeat: 660 / 70

Advancing to step 3:
70 can be fit into 660 9 times, resulting in a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 630 away from 660, we end up with 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 70

Step 4:
When dividing 303 by 70, we get 4 with a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 94.0
The remainder is 23 after subtracting 280 from 303.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 70

On to step 5:
The number 70 fits into 233 3 times, leaving a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 943.0
If we subtract 210 from 233, we get 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 70

On to step 6:
236 divided by 70 is 3 with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 9433.0
The remainder is 26 after subtracting 210 from 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
The number 70 fits into 260 3 times, leaving a remainder of 50.
The next digit of our result is 3. 
Result so far: 9433.3
Subtracting 210 from 260 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
500 divided by 70 is 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 9433.37
If we take 490 away from 500, we end up 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.

Moving on to step 9:
100 divided by 70 is 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 9433.371
If we subtract 70 from 100, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
When dividing 300 by 70, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 9433.3714
Deduct 280 from 300 and we're left 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.

Going ahead to step 11:
When dividing 200 by 70, we get 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 9433.37142
Subtracting 140 from 200 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
70 goes into 600 8 times with a remainder of 40.
The next digit of our result is 8. 
Result so far: 9433.371428
Subtracting 560 from 600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
400 divided by 70 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 9433.3714285
Subtracting 350 from 400 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
If we divide 500 by 70, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 9433.37142857
Subtract 490 from 500 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 9433.37142857, with a leftover of 1e-08.
