We look at the division of 140665 by 70 
The aim is to understand the frequency of 70 in 140665.

Advancing to step 1:
70 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 70

On to step 2:
14 divided by 70 is 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 70

Advancing to step 3:
The number 70 fits into 140 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 140 from 140 and we're left with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 70

Moving on to step 4:
The number 70 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 70

Step 5:
70 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 200.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 70

Moving on to step 6:
70 can be fit into 665 9 times, resulting in a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 2009.0
Subtract 630 from 665 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
70 can be fit into 350 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 2009.5
Subtracting 350 from 350 leaves us 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 8:
The number 70 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2009.5
Deduct 0 from 0 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.

Going ahead to step 9:
70 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 2009.5
Subtracting 0 from 0 leaves us 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 final outcome is 2009.5, with a leftover of 0.0.
