Let's divide 439963 by 71
The aim is to understand the frequency of 71 in 439963.

On to step 1:
4 divided by 71 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 71

Moving on to step 2:
If we divide 43 by 71, we get 0 and a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 71

Step 3:
71 goes into 439 6 times with a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 13 after subtracting 426 from 439.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 71

Step 4:
The number 71 fits into 139 1 times, leaving a remainder of 68.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Deduct 71 from 139 and we're left with 68.
Take the next digit (6) from the dividend and append it to 68, then repeat: 686 / 71

Advancing to step 5:
When dividing 686 by 71, we get 9 with a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 619.0
If we take 639 away from 686, we end up with 47.
Fetch the next digit (3) from the dividend, attach it to 47 and continue: 473 / 71

Let's proceed to step 6:
When dividing 473 by 71, we get 6 with a remainder of 47.
Use 6 as the next digit of our solution. 
Result so far: 6196.0
If we subtract 426 from 473, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
When dividing 470 by 71, we get 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 6196.6
If we take 426 away from 470, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 8:
If we divide 440 by 71, we get 6 and a remainder of 14.
The next digit of our result is 6. 
Result so far: 6196.66
Deduct 426 from 440 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 6196.66, and the remainder is 0.014.
