We're dividing 70234 by 71 
The aim is to understand the frequency of 71 in 70234.

Advancing to step 1:
71 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 71

Step 2:
The number 71 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Grab the next digit (2) from the dividend, add it to 70, then carry on: 702 / 71

Let's proceed to step 3:
If we divide 702 by 71, we get 9 and a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 639 from 702 to get 63.
Append the next digit (3) from the dividend to 63 and continue with: 633 / 71

Let's proceed to step 4:
When dividing 633 by 71, we get 8 with a remainder of 65.
Write down 8 as next digit of the result. 
Result so far: 98.0
If we subtract 568 from 633, we get 65.
Bring next digit (4) of the dividend behind the 65 and repeat the process: 654 / 71

Step 5:
The number 71 fits into 654 9 times, leaving a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 989.0
Subtracting 639 from 654 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 6:
71 can be fit into 150 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 989.2
If we take 142 away from 150, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
80 divided by 71 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 989.21
Subtract 71 from 80 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
71 can be fit into 90 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 989.211
If we take 71 away from 90, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 989.211, with a leftover of 0.0019.
