We divide 209956 by 71
The aim is to understand the frequency of 71 in 209956.

Step 1:
The number 71 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 71

Step 2:
When dividing 20 by 71, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 71

Step 3:
If we divide 209 by 71, we get 2 and a remainder of 67.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 142 away from 209, we end up with 67.
Take the next digit (9) from the dividend and append it to 67, then repeat: 679 / 71

Let's proceed to step 4:
71 goes into 679 9 times with a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we take 639 away from 679, we end up with 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 71

Going ahead to step 5:
405 divided by 71 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 295.0
Subtract 355 from 405 to get 50.
Fetch the next digit (6) from the dividend, attach it to 50 and continue: 506 / 71

Step 6:
If we divide 506 by 71, we get 7 and a remainder of 9.
The next digit of our result is 7. 
Result so far: 2957.0
Subtracting 497 from 506 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 7:
The number 71 fits into 90 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 2957.1
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.

Going ahead to step 8:
190 divided by 71 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 2957.12
If we take 142 away from 190, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
When dividing 480 by 71, we get 6 with a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 2957.126
Deduct 426 from 480 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
If we divide 540 by 71, we get 7 and a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 2957.1267
Subtract 497 from 540 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 11:
If we divide 430 by 71, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 2957.12676
If we take 426 away from 430, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
If we divide 40 by 71, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 2957.12676
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
When dividing 400 by 71, we get 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 2957.1267605
Subtracting 355 from 400 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 14:
When dividing 450 by 71, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 2957.12676056
The remainder is 24 after subtracting 426 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 2957.12676056, with a leftover of 2.4e-08.
