We look at the division of 696449 by 70 
The aim is to understand the frequency of 70 in 696449.

On to step 1:
When dividing 6 by 70, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 70

Advancing to step 2:
70 goes into 69 0 times with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Append the next digit (6) from the dividend to 69 and continue with: 696 / 70

Going ahead to step 3:
696 divided by 70 is 9 with a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 630 from 696 leaves us with 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 70

On to step 4:
If we divide 664 by 70, we get 9 and a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtract 630 from 664 to get 34.
Append the next digit (4) from the dividend to 34 and continue with: 344 / 70

On to step 5:
344 divided by 70 is 4 with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 994.0
Subtracting 280 from 344 leaves us with 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 70

Step 6:
When dividing 649 by 70, we get 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 9949.0
The remainder is 19 after subtracting 630 from 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
If we divide 190 by 70, we get 2 and a remainder of 50.
The next digit of our result is 2. 
Result so far: 9949.2
Subtract 140 from 190 to get 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:
When dividing 500 by 70, we get 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 9949.27
Deduct 490 from 500 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.

Let's proceed to step 9:
70 can be fit into 100 1 times, resulting in a remainder of 30.
The next digit of our result is 1. 
Result so far: 9949.271
Deduct 70 from 100 and we're left 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.

Advancing to step 10:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 9949.2714
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.

Let's proceed to step 11:
200 divided by 70 is 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 9949.27142
If we subtract 140 from 200, we 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 12:
600 divided by 70 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 9949.271428
Deduct 560 from 600 and we're left 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.

Moving on to step 13:
70 goes into 400 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 9949.2714285
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 14:
70 goes into 500 7 times with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 9949.27142857
If we subtract 490 from 500, we 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 9949.27142857, with a leftover of 1e-08.
