We look at the division of 783496 by 71 
The aim is to understand the frequency of 71 in 783496.

Step 1:
The number 71 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 71

Let's proceed to step 2:
If we divide 78 by 71, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 71 from 78 and we're left with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 71

On to step 3:
If we divide 73 by 71, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 71 from 73, we get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 71

Moving on to step 4:
The number 71 fits into 24 0 times, leaving a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 110.0
The remainder is 24 after subtracting 0 from 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 71

Moving on to step 5:
If we divide 249 by 71, we get 3 and a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 1103.0
The remainder is 36 after subtracting 213 from 249.
Bring next digit (6) of the dividend behind the 36 and repeat the process: 366 / 71

Advancing to step 6:
The number 71 fits into 366 5 times, leaving a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 11035.0
Subtracting 355 from 366 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
71 goes into 110 1 times with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 11035.1
Deduct 71 from 110 and we're left 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.

Moving on to step 8:
71 goes into 390 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 11035.15
Subtract 355 from 390 to get 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 9:
The number 71 fits into 350 4 times, leaving a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 11035.154
Deduct 284 from 350 and we're left 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 10:
The number 71 fits into 660 9 times, leaving a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 11035.1549
Subtract 639 from 660 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 11:
71 goes into 210 2 times with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 11035.15492
If we subtract 142 from 210, we 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.

Step 12:
680 divided by 71 is 9 with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 11035.154929
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.

Going ahead to step 13:
71 goes into 410 5 times with a remainder of 55.
The next digit of our result is 5. 
Result so far: 11035.1549295
If we take 355 away from 410, we end up 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 14:
71 can be fit into 550 7 times, resulting in a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 11035.15492957
If we subtract 497 from 550, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

After the division, we end up with 11035.15492957 and a remainder of 5.3e-08.
