21673 divided by 71 
The aim is to understand the frequency of 71 in 21673.

Step 1:
The number 71 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 71

Advancing to step 2:
The number 71 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 71

Step 3:
If we divide 216 by 71, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 213 from 216, we get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 71

Advancing to step 4:
If we divide 37 by 71, we get 0 and a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we subtract 0 from 37, we get 37.
Include the next digit (3) from the dividend after 37, then repeat: 373 / 71

Let's proceed to step 5:
The number 71 fits into 373 5 times, leaving a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 305.0
Deduct 355 from 373 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 6:
When dividing 180 by 71, we get 2 with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 305.2
If we subtract 142 from 180, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
380 divided by 71 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 305.25
Deduct 355 from 380 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
When dividing 250 by 71, we get 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 305.253
Subtracting 213 from 250 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
If we divide 370 by 71, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 305.2535
Subtract 355 from 370 to get 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 10:
When dividing 150 by 71, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 305.25352
The remainder is 8 after subtracting 142 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
80 divided by 71 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 305.253521
Subtracting 71 from 80 leaves us with 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 12:
71 goes into 90 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 305.2535211
Subtracting 71 from 90 leaves us 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 result is 305.2535211 with a remainder of 1.9e-07.
