893703 ÷ 71 
The aim is to understand the frequency of 71 in 893703.

Let's proceed to step 1:
If we divide 8 by 71, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 71

Step 2:
If we divide 89 by 71, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 71 from 89 to get 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 71

Going ahead to step 3:
183 divided by 71 is 2 with a remainder of 41.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 142 from 183, we get 41.
Bring next digit (7) of the dividend behind the 41 and repeat the process: 417 / 71

Going ahead to step 4:
The number 71 fits into 417 5 times, leaving a remainder of 62.
Use 5 as the next digit of our solution. 
Result so far: 125.0
Deduct 355 from 417 and we're left with 62.
Include the next digit (0) from the dividend after 62, then repeat: 620 / 71

Going ahead to step 5:
71 can be fit into 620 8 times, resulting in a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 1258.0
If we take 568 away from 620, we end up with 52.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 71

Let's proceed to step 6:
The number 71 fits into 523 7 times, leaving a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 12587.0
Subtract 497 from 523 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
If we divide 260 by 71, we get 3 and a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 12587.3
If we subtract 213 from 260, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 8:
71 goes into 470 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 12587.36
If we subtract 426 from 470, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
If we divide 440 by 71, we get 6 and a remainder of 14.
The next digit of our result is 6. 
Result so far: 12587.366
Subtracting 426 from 440 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 12587.366, with a leftover of 0.0014.
