Let's divide 330991 by 71
The aim is to understand the frequency of 71 in 330991.

Let's proceed to step 1:
71 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 71

Step 2:
The number 71 fits into 33 0 times, leaving a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 71

Step 3:
When dividing 330 by 71, we get 4 with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 284 from 330 and we're left with 46.
Bring next digit (9) of the dividend behind the 46 and repeat the process: 469 / 71

Going ahead to step 4:
469 divided by 71 is 6 with a remainder of 43.
The next digit of our result is 6. 
Result so far: 46.0
If we take 426 away from 469, we end up with 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 71

Let's proceed to step 5:
71 can be fit into 439 6 times, resulting in a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 466.0
Subtracting 426 from 439 leaves us with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 71

Let's proceed to step 6:
If we divide 131 by 71, we get 1 and a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 4661.0
Deduct 71 from 131 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
The number 71 fits into 600 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 4661.8
If we subtract 568 from 600, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
When dividing 320 by 71, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 4661.84
Subtracting 284 from 320 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
360 divided by 71 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 4661.845
Deduct 355 from 360 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
71 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 4661.845
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
The number 71 fits into 500 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 4661.84507
Subtracting 497 from 500 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 12:
When dividing 30 by 71, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 4661.84507
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
If we divide 300 by 71, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 4661.8450704
If we subtract 284 from 300, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
71 goes into 160 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 4661.84507042
Deduct 142 from 160 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.

The final outcome is 4661.84507042, with a leftover of 1.8e-08.
