We look at the division of 61696311 by 70 
The aim is to understand the frequency of 70 in 61696311.

On to step 1:
If we divide 6 by 70, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 70

Step 2:
The number 70 fits into 61 0 times, leaving a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Append the next digit (6) from the dividend to 61 and continue with: 616 / 70

Going ahead to step 3:
If we divide 616 by 70, we get 8 and a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 560 away from 616, we end up with 56.
Take the next digit (9) from the dividend and append it to 56, then repeat: 569 / 70

Moving on to step 4:
569 divided by 70 is 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
If we subtract 560 from 569, we get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 70

Let's proceed to step 5:
If we divide 96 by 70, we get 1 and a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 881.0
Deduct 70 from 96 and we're left with 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 70

On to step 6:
263 divided by 70 is 3 with a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 8813.0
The remainder is 53 after subtracting 210 from 263.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 70

Let's proceed to step 7:
70 goes into 531 7 times with a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 88137.0
Deduct 490 from 531 and we're left with 41.
Append the next digit (1) from the dividend to 41 and continue with: 411 / 70

Step 8:
70 goes into 411 5 times with a remainder of 61.
Put 5 as the next digit of the answer. 
Result so far: 881375.0
Subtract 350 from 411 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 9:
When dividing 610 by 70, we get 8 with a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 881375.8
Subtracting 560 from 610 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.

Step 10:
If we divide 500 by 70, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 881375.87
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.

Going ahead to step 11:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 881375.871
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.

Moving on to step 12:
300 divided by 70 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 881375.8714
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.

Let's proceed to step 13:
70 goes into 200 2 times with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 881375.87142
Subtract 140 from 200 to 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.

Step 14:
The number 70 fits into 600 8 times, leaving a remainder of 40.
The next digit of our result is 8. 
Result so far: 881375.871428
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 15:
If we divide 400 by 70, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 881375.8714285
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.

Step 16:
500 divided by 70 is 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 881375.87142857
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 result is 881375.87142857 with a remainder of 1e-08.
