We look at the division of 34430 by 70 
The aim is to understand the frequency of 70 in 34430.

Let's proceed to step 1:
When dividing 3 by 70, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 70

Advancing to step 2:
70 can be fit into 34 0 times, resulting in a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 70

Going ahead to step 3:
If we divide 344 by 70, we get 4 and a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 64 after subtracting 280 from 344.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 70

Going ahead to step 4:
If we divide 643 by 70, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 49.0
If we subtract 630 from 643, we get 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 70

Going ahead to step 5:
If we divide 130 by 70, we get 1 and a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 491.0
Deduct 70 from 130 and we're left 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.

Advancing to step 6:
When dividing 600 by 70, we get 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 491.8
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
If we divide 400 by 70, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 491.85
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.

Going ahead to step 8:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 491.857
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.

Let's proceed to step 9:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 491.8571
Subtract 70 from 100 to 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.

On to step 10:
70 goes into 300 4 times with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 491.85714
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.

Step 11:
70 can be fit into 200 2 times, resulting in a remainder of 60.
The next digit of our result is 2. 
Result so far: 491.857142
Deduct 140 from 200 and we're left 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:
600 divided by 70 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 491.8571428
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.

Going ahead to step 13:
When dividing 400 by 70, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 491.85714285
If we take 350 away from 400, we end up 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.

Our division results in 491.85714285 with a remaining 5e-08.
