690723 divided by 71 
The aim is to understand the frequency of 71 in 690723.

Moving on to step 1:
The number 71 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 71

Step 2:
71 goes into 69 0 times with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Fetch the next digit (0) from the dividend, attach it to 69 and continue: 690 / 71

Going ahead to step 3:
71 can be fit into 690 9 times, resulting in a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 639 from 690 and we're left with 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 71

Moving on to step 4:
517 divided by 71 is 7 with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
The remainder is 20 after subtracting 497 from 517.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 71

Advancing to step 5:
71 goes into 202 2 times with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 972.0
The remainder is 60 after subtracting 142 from 202.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 71

Moving on to step 6:
When dividing 603 by 71, we get 8 with a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 9728.0
The remainder is 35 after subtracting 568 from 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
71 can be fit into 350 4 times, resulting in a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 9728.4
Subtracting 284 from 350 leaves us 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 8:
If we divide 660 by 71, we get 9 and a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 9728.49
If we take 639 away from 660, we end up with 21.
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 9:
When dividing 210 by 71, we get 2 with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 9728.492
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.

Going ahead to step 10:
680 divided by 71 is 9 with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 9728.4929
If we take 639 away from 680, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 11:
If we divide 410 by 71, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 9728.49295
If we subtract 355 from 410, we get 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 12:
If we divide 550 by 71, we get 7 and a remainder of 53.
The next digit of our result is 7. 
Result so far: 9728.492957
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.

Moving on to step 13:
If we divide 530 by 71, we get 7 and a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 9728.4929577
Subtract 497 from 530 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final result is 9728.4929577 with a remainder of 3.3e-07.
