Let's divide 639683 by 71
The aim is to understand the frequency of 71 in 639683.

Moving on to step 1:
When dividing 6 by 71, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 71

On to step 2:
When dividing 63 by 71, we get 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 71

On to step 3:
The number 71 fits into 639 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 639 from 639 leaves us with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 71

Advancing to step 4:
71 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 90.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 71

Going ahead to step 5:
71 can be fit into 68 0 times, resulting in a remainder of 68.
The next digit of our result is 0. 
Result so far: 900.0
Subtracting 0 from 68 leaves us with 68.
Append the next digit (3) from the dividend to 68 and continue with: 683 / 71

Going ahead to step 6:
When dividing 683 by 71, we get 9 with a remainder of 44.
The next digit of our result is 9. 
Result so far: 9009.0
If we subtract 639 from 683, 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.

Going ahead to step 7:
If we divide 440 by 71, we get 6 and a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 9009.6
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.

Going ahead to step 8:
71 can be fit into 140 1 times, resulting in a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 9009.61
If we take 71 away from 140, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 9:
71 goes into 690 9 times with a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 9009.619
Deduct 639 from 690 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 10:
71 goes into 510 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 9009.6197
Subtract 497 from 510 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 11:
71 can be fit into 130 1 times, resulting in a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 9009.61971
Subtracting 71 from 130 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 12:
71 goes into 590 8 times with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 9009.619718
Subtracting 568 from 590 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
The number 71 fits into 220 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 9009.6197183
Subtract 213 from 220 to 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 14:
71 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 9009.6197183
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 9009.6197183 with a balance of 7e-08.
