144279 divided by 71 
The aim is to understand the frequency of 71 in 144279.

On to step 1:
1 divided by 71 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 71

On to step 2:
14 divided by 71 is 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 71

On to step 3:
The number 71 fits into 144 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 142 from 144 to get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 71

Step 4:
71 goes into 22 0 times with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Deduct 0 from 22 and we're left with 22.
Bring next digit (7) of the dividend behind the 22 and repeat the process: 227 / 71

Going ahead to step 5:
If we divide 227 by 71, we get 3 and a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 203.0
The remainder is 14 after subtracting 213 from 227.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 71

Going ahead to step 6:
149 divided by 71 is 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2032.0
Subtracting 142 from 149 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
The number 71 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 2032.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
71 can be fit into 700 9 times, resulting in a remainder of 61.
The next digit of our result is 9. 
Result so far: 2032.09
Subtracting 639 from 700 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 9:
If we divide 610 by 71, we get 8 and a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 2032.098
If we take 568 away from 610, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
If we divide 420 by 71, we get 5 and a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 2032.0985
If we subtract 355 from 420, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 11:
71 goes into 650 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 2032.09859
Subtracting 639 from 650 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 12:
110 divided by 71 is 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 2032.098591
The remainder is 39 after subtracting 71 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 13:
71 goes into 390 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 2032.0985915
If we subtract 355 from 390, we 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.

On to step 14:
71 goes into 350 4 times with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 2032.09859154
Subtract 284 from 350 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 2032.09859154, with a leftover of 6.6e-08.
