We look at the division of 206990 by 70 
The aim is to understand the frequency of 70 in 206990.

Moving on to step 1:
70 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 70

Moving on to step 2:
If we divide 20 by 70, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 70

Let's proceed to step 3:
70 can be fit into 206 2 times, resulting in a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 140 from 206 leaves us with 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 70

Step 4:
The number 70 fits into 669 9 times, leaving a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 29.0
Deduct 630 from 669 and we're left with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 70

Going ahead to step 5:
The number 70 fits into 399 5 times, leaving a remainder of 49.
Put 5 as the next digit of the answer. 
Result so far: 295.0
Deduct 350 from 399 and we're left with 49.
Include the next digit (0) from the dividend after 49, then repeat: 490 / 70

Moving on to step 6:
490 divided by 70 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 2957.0
The remainder is 0 after subtracting 490 from 490.
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 7:
70 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2957.0
Subtract 0 from 0 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 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2957.0
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.

The quotient of the division is 2957.0, and the remainder is 0.0.
