821576 ÷ 70 
The aim is to understand the frequency of 70 in 821576.

Step 1:
70 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 70

Going ahead to step 2:
The number 70 fits into 82 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 70 away from 82, we end up with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 70

On to step 3:
121 divided by 70 is 1 with a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 70 away from 121, we end up with 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 70

On to step 4:
515 divided by 70 is 7 with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 117.0
Subtracting 490 from 515 leaves us with 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 70

Advancing to step 5:
The number 70 fits into 257 3 times, leaving a remainder of 47.
The next digit of our result is 3. 
Result so far: 1173.0
The remainder is 47 after subtracting 210 from 257.
Fetch the next digit (6) from the dividend, attach it to 47 and continue: 476 / 70

Let's proceed to step 6:
476 divided by 70 is 6 with a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 11736.0
The remainder is 56 after subtracting 420 from 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 7:
70 can be fit into 560 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 11736.8
Deduct 560 from 560 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.

On to step 8:
70 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11736.8
If we take 0 away from 0, we end up 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.

Going ahead to step 9:
70 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11736.8
If we take 0 away from 0, we end up 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.

Our division results in 11736.8 with a remaining 0.0.
