143871 divided by 70 
The aim is to understand the frequency of 70 in 143871.

Step 1:
The number 70 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 70

Advancing to step 2:
14 divided by 70 is 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 70

Step 3:
If we divide 143 by 70, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 140 from 143, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 70

Going ahead to step 4:
70 goes into 38 0 times with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 38 leaves us with 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 70

Step 5:
When dividing 387 by 70, we get 5 with a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 205.0
Subtract 350 from 387 to get 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 70

Advancing to step 6:
The number 70 fits into 371 5 times, leaving a remainder of 21.
The number 5 becomes the next digit in our result. 
Result so far: 2055.0
The remainder is 21 after subtracting 350 from 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
When dividing 210 by 70, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 2055.3
If we take 210 away from 210, 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.

On to step 8:
70 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2055.3
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.

Step 9:
The number 70 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2055.3
The remainder is 0 after subtracting 0 from 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 2055.3, and the remainder is 0.0.
