Let's divide 819984 by 70
The aim is to understand the frequency of 70 in 819984.

Let's proceed to step 1:
If we divide 8 by 70, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 70

Moving on to step 2:
70 can be fit into 81 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 70 from 81, we get 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 70

Going ahead to step 3:
If we divide 119 by 70, we get 1 and a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 70 away from 119, we end up with 49.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 70

Step 4:
The number 70 fits into 499 7 times, leaving a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
If we take 490 away from 499, we end up with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 70

Moving on to step 5:
98 divided by 70 is 1 with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1171.0
If we take 70 away from 98, we end up with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 70

Advancing to step 6:
The number 70 fits into 284 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 11714.0
The remainder is 4 after subtracting 280 from 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
If we divide 40 by 70, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 11714.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
70 goes into 400 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 11714.05
Deduct 350 from 400 and we're left 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.

Advancing to step 9:
The number 70 fits into 500 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 11714.057
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.

Step 10:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 11714.0571
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.

Advancing to step 11:
300 divided by 70 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 11714.05714
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 12:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 11714.057142
The remainder is 60 after subtracting 140 from 200.
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 13:
If we divide 600 by 70, we get 8 and a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 11714.0571428
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.

Step 14:
If we divide 400 by 70, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 11714.05714285
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.

After the division, we end up with 11714.05714285 and a remainder of 5e-08.
