Let's divide 20210 by 70
The aim is to understand the frequency of 70 in 20210.

On to step 1:
When dividing 2 by 70, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 70

Going ahead to step 2:
If we divide 20 by 70, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 70

On to step 3:
The number 70 fits into 202 2 times, leaving a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 140 from 202 to get 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 70

On to step 4:
When dividing 621 by 70, we get 8 with a remainder of 61.
The next digit of our result is 8. 
Result so far: 28.0
Deduct 560 from 621 and we're left with 61.
Append the next digit (0) from the dividend to 61 and continue with: 610 / 70

Moving on to step 5:
The number 70 fits into 610 8 times, leaving a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 288.0
Subtract 560 from 610 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 6:
70 goes into 500 7 times with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 288.7
Subtract 490 from 500 to 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.

Advancing to step 7:
100 divided by 70 is 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 288.71
If we subtract 70 from 100, we 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.

On to step 8:
If we divide 300 by 70, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 288.714
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
70 goes into 200 2 times with a remainder of 60.
The next digit of our result is 2. 
Result so far: 288.7142
If we take 140 away from 200, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
When dividing 600 by 70, we get 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 288.71428
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.

Advancing to step 11:
When dividing 400 by 70, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 288.714285
The remainder is 50 after subtracting 350 from 400.
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 12:
If we divide 500 by 70, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 288.7142857
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.

Let's proceed to step 13:
If we divide 100 by 70, we get 1 and a remainder of 30.
The next digit of our result is 1. 
Result so far: 288.71428571
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.

Our division results in 288.71428571 with a remaining 3e-08.
