Let's divide 72589097 by 71
The aim is to understand the frequency of 71 in 72589097.

On to step 1:
7 divided by 71 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 71

Step 2:
If we divide 72 by 71, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 71 away from 72, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 71

Step 3:
15 divided by 71 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 15 leaves us with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 71

Moving on to step 4:
71 goes into 158 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Subtracting 142 from 158 leaves us with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 71

Advancing to step 5:
71 can be fit into 169 2 times, resulting in a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 1022.0
Deduct 142 from 169 and we're left with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 71

Advancing to step 6:
The number 71 fits into 270 3 times, leaving a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 10223.0
The remainder is 57 after subtracting 213 from 270.
Take the next digit (9) from the dividend and append it to 57, then repeat: 579 / 71

Going ahead to step 7:
71 goes into 579 8 times with a remainder of 11.
The next digit of our result is 8. 
Result so far: 102238.0
The remainder is 11 after subtracting 568 from 579.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 71

Step 8:
When dividing 117 by 71, we get 1 with a remainder of 46.
The next digit of our result is 1. 
Result so far: 1022381.0
If we take 71 away from 117, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 9:
71 goes into 460 6 times with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 1022381.6
If we take 426 away from 460, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
The number 71 fits into 340 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 1022381.64
If we subtract 284 from 340, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
71 goes into 560 7 times with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 1022381.647
Subtracting 497 from 560 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 12:
When dividing 630 by 71, we get 8 with a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 1022381.6478
The remainder is 62 after subtracting 568 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 13:
71 can be fit into 620 8 times, resulting in a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 1022381.64788
Subtract 568 from 620 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 1022381.64788, and the remainder is 5.2e-05.
