We look at the division of 210302 by 70 
The aim is to understand the frequency of 70 in 210302.

Advancing to step 1:
2 divided by 70 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 70

Let's proceed to step 2:
21 divided by 70 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 70

On to step 3:
If we divide 210 by 70, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 210 from 210 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 70

Step 4:
70 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 30.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 70

Going ahead to step 5:
When dividing 30 by 70, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 300.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 70

Moving on to step 6:
302 divided by 70 is 4 with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 3004.0
If we subtract 280 from 302, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
70 goes into 220 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 3004.3
If we subtract 210 from 220, 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.

Let's proceed to step 8:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 3004.31
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.

Step 9:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 3004.314
If we take 280 away from 300, we end up 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.

Going ahead to step 10:
70 can be fit into 200 2 times, resulting in a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 3004.3142
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 11:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 3004.31428
If we take 560 away from 600, we end up 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.

Advancing to step 12:
400 divided by 70 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 3004.314285
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 13:
The number 70 fits into 500 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 3004.3142857
Subtracting 490 from 500 leaves us 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 14:
100 divided by 70 is 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 3004.31428571
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 3004.31428571 and a remainder of 3e-08.
