Let's divide 623828 by 71
The aim is to understand the frequency of 71 in 623828.

Moving on to step 1:
When dividing 6 by 71, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 71

Advancing to step 2:
71 can be fit into 62 0 times, resulting in a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Include the next digit (3) from the dividend after 62, then repeat: 623 / 71

Moving on to step 3:
The number 71 fits into 623 8 times, leaving a remainder of 55.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 55 after subtracting 568 from 623.
Bring next digit (8) of the dividend behind the 55 and repeat the process: 558 / 71

Step 4:
When dividing 558 by 71, we get 7 with a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Deduct 497 from 558 and we're left with 61.
Take the next digit (2) from the dividend and append it to 61, then repeat: 612 / 71

Going ahead to step 5:
71 goes into 612 8 times with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 878.0
Subtract 568 from 612 to get 44.
Append the next digit (8) from the dividend to 44 and continue with: 448 / 71

Advancing to step 6:
71 goes into 448 6 times with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 8786.0
Subtract 426 from 448 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
When dividing 220 by 71, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 8786.3
If we subtract 213 from 220, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
71 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 8786.3
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
The number 71 fits into 700 9 times, leaving a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 8786.309
Deduct 639 from 700 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 10:
610 divided by 71 is 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 8786.3098
Subtract 568 from 610 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
If we divide 420 by 71, we get 5 and a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 8786.30985
The remainder is 65 after subtracting 355 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 12:
When dividing 650 by 71, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 8786.309859
Subtracting 639 from 650 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 13:
When dividing 110 by 71, we get 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 8786.3098591
If we take 71 away from 110, we end up 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.

Going ahead to step 14:
If we divide 390 by 71, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 8786.30985915
Deduct 355 from 390 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 8786.30985915 and a remainder of 3.5e-08.
