We're dividing 331822 by 71 
The aim is to understand the frequency of 71 in 331822.

On to step 1:
The number 71 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 71

On to step 2:
When dividing 33 by 71, we get 0 with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 71

Step 3:
If we divide 331 by 71, we get 4 and a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 47 after subtracting 284 from 331.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 71

Going ahead to step 4:
71 goes into 478 6 times with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we take 426 away from 478, we end up with 52.
Append the next digit (2) from the dividend to 52 and continue with: 522 / 71

Step 5:
The number 71 fits into 522 7 times, leaving a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 467.0
If we subtract 497 from 522, we get 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 71

Advancing to step 6:
71 can be fit into 252 3 times, resulting in a remainder of 39.
The next digit of our result is 3. 
Result so far: 4673.0
If we take 213 away from 252, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
71 can be fit into 390 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 4673.5
Subtracting 355 from 390 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
When dividing 350 by 71, we get 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 4673.54
If we take 284 away from 350, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 9:
If we divide 660 by 71, we get 9 and a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 4673.549
The remainder is 21 after subtracting 639 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 10:
71 goes into 210 2 times with a remainder of 68.
The next digit of our result is 2. 
Result so far: 4673.5492
Subtract 142 from 210 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 11:
71 can be fit into 680 9 times, resulting in a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 4673.54929
Subtract 639 from 680 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 12:
The number 71 fits into 410 5 times, leaving a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 4673.549295
Deduct 355 from 410 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 13:
71 goes into 550 7 times with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 4673.5492957
The remainder is 53 after subtracting 497 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 14:
71 goes into 530 7 times with a remainder of 33.
The next digit of our result is 7. 
Result so far: 4673.54929577
The remainder is 33 after subtracting 497 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

After the division, we end up with 4673.54929577 and a remainder of 3.3e-08.
