970515 ÷ 70 
The aim is to understand the frequency of 70 in 970515.

Step 1:
9 divided by 70 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 70

Moving on to step 2:
The number 70 fits into 97 1 times, leaving a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 70 from 97 leaves us with 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 70

Let's proceed to step 3:
When dividing 270 by 70, we get 3 with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 210 away from 270, we end up with 60.
Append the next digit (5) from the dividend to 60 and continue with: 605 / 70

Step 4:
When dividing 605 by 70, we get 8 with a remainder of 45.
Use 8 as the next digit of our solution. 
Result so far: 138.0
Subtracting 560 from 605 leaves us with 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 70

Step 5:
If we divide 451 by 70, we get 6 and a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 1386.0
The remainder is 31 after subtracting 420 from 451.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 70

Going ahead to step 6:
The number 70 fits into 315 4 times, leaving a remainder of 35.
Write down 4 as next digit of the result. 
Result so far: 13864.0
Subtract 280 from 315 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
350 divided by 70 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 13864.5
Subtract 350 from 350 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
70 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13864.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
70 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13864.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 13864.5 with a remaining 0.0.
