We look at the division of 531459 by 70 
The aim is to understand the frequency of 70 in 531459.

Advancing to step 1:
70 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 70

Moving on to step 2:
When dividing 53 by 70, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (1) from the dividend after 53, then repeat: 531 / 70

Step 3:
When dividing 531 by 70, we get 7 with a remainder of 41.
The next digit of our result is 7. 
Result so far: 7.0
If we take 490 away from 531, we end up with 41.
Append the next digit (4) from the dividend to 41 and continue with: 414 / 70

Step 4:
70 can be fit into 414 5 times, resulting in a remainder of 64.
The next digit of our result is 5. 
Result so far: 75.0
Deduct 350 from 414 and we're left with 64.
Take the next digit (5) from the dividend and append it to 64, then repeat: 645 / 70

Step 5:
When dividing 645 by 70, we get 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 759.0
Subtract 630 from 645 to get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 70

Step 6:
70 goes into 159 2 times with a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 7592.0
Deduct 140 from 159 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
When dividing 190 by 70, we get 2 with a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 7592.2
The remainder is 50 after subtracting 140 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 7592.27
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 goes into 100 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 7592.271
Subtracting 70 from 100 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 10:
300 divided by 70 is 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 7592.2714
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
When dividing 200 by 70, we get 2 with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 7592.27142
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.

On to step 12:
70 can be fit into 600 8 times, resulting in a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 7592.271428
The remainder is 40 after subtracting 560 from 600.
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 13:
If we divide 400 by 70, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 7592.2714285
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.

Moving on to step 14:
70 goes into 500 7 times with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 7592.27142857
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.

After the division, we end up with 7592.27142857 and a remainder of 1e-08.
