Let's divide 349590 by 71
The aim is to understand the frequency of 71 in 349590.

Going ahead 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
If we take 0 away from 3, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 71

Let's proceed to step 2:
If we divide 34 by 71, we get 0 and a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Take the next digit (9) from the dividend and append it to 34, then repeat: 349 / 71

Moving on to step 3:
71 goes into 349 4 times with a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 284 from 349 and we're left with 65.
Fetch the next digit (5) from the dividend, attach it to 65 and continue: 655 / 71

Step 4:
655 divided by 71 is 9 with a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtracting 639 from 655 leaves us with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 71

Let's proceed to step 5:
71 goes into 169 2 times with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 492.0
If we take 142 away from 169, we end up with 27.
Bring next digit (0) of the dividend behind the 27 and repeat the process: 270 / 71

Step 6:
270 divided by 71 is 3 with a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 4923.0
Deduct 213 from 270 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 7:
71 goes into 570 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 4923.8
The remainder is 2 after subtracting 568 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
If we divide 20 by 71, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 4923.8
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
200 divided by 71 is 2 with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 4923.802
The remainder is 58 after subtracting 142 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
71 goes into 580 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 4923.8028
Subtract 568 from 580 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
120 divided by 71 is 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 4923.80281
The remainder is 49 after subtracting 71 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 12:
490 divided by 71 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 4923.802816
If we subtract 426 from 490, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
If we divide 640 by 71, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 4923.8028169
Subtracting 639 from 640 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
10 divided by 71 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 4923.8028169
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 4923.8028169 with a remainder of 1e-08.
