We divide 152981 by 70
The aim is to understand the frequency of 70 in 152981.

Going ahead to step 1:
When dividing 1 by 70, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 70

Going ahead to step 2:
If we divide 15 by 70, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 70

Let's proceed to step 3:
152 divided by 70 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 140 away from 152, we end up with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 70

On to step 4:
129 divided by 70 is 1 with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtracting 70 from 129 leaves us with 59.
Bring next digit (8) of the dividend behind the 59 and repeat the process: 598 / 70

Moving on to step 5:
If we divide 598 by 70, we get 8 and a remainder of 38.
The next digit of our result is 8. 
Result so far: 218.0
If we subtract 560 from 598, we get 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 70

Moving on to step 6:
If we divide 381 by 70, we get 5 and a remainder of 31.
Write down 5 as next digit of the result. 
Result so far: 2185.0
The remainder is 31 after subtracting 350 from 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
The number 70 fits into 310 4 times, leaving a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 2185.4
Subtract 280 from 310 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.

On to step 8:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 2185.44
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 2185.44 with a remainder of 0.02.
