We look at the division of 20993915 by 710 
The aim is to understand the frequency of 710 in 20993915.

Going ahead to step 1:
The number 710 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 710

Advancing to step 2:
20 divided by 710 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 710

Moving on to step 3:
The number 710 fits into 209 0 times, leaving a remainder of 209.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 209 to get 209.
Fetch the next digit (9) from the dividend, attach it to 209 and continue: 2099 / 710

Let's proceed to step 4:
The number 710 fits into 2099 2 times, leaving a remainder of 679.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1420 from 2099 leaves us with 679.
Grab the next digit (3) from the dividend, add it to 679, then carry on: 6793 / 710

Step 5:
6793 divided by 710 is 9 with a remainder of 403.
Write down 9 as next digit of the result. 
Result so far: 29.0
Deduct 6390 from 6793 and we're left with 403.
Bring next digit (9) of the dividend behind the 403 and repeat the process: 4039 / 710

On to step 6:
710 can be fit into 4039 5 times, resulting in a remainder of 489.
The next digit of our result is 5. 
Result so far: 295.0
Subtract 3550 from 4039 to get 489.
Fetch the next digit (1) from the dividend, attach it to 489 and continue: 4891 / 710

Moving on to step 7:
The number 710 fits into 4891 6 times, leaving a remainder of 631.
Write down 6 as next digit of the result. 
Result so far: 2956.0
If we subtract 4260 from 4891, we get 631.
Append the next digit (5) from the dividend to 631 and continue with: 6315 / 710

Step 8:
6315 divided by 710 is 8 with a remainder of 635.
Put 8 as the next digit of the answer. 
Result so far: 29568.0
Deduct 5680 from 6315 and we're left with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Going ahead to step 9:
The number 710 fits into 6350 8 times, leaving a remainder of 670.
Use 8 as the next digit of our solution. 
Result so far: 29568.8
The remainder is 670 after subtracting 5680 from 6350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Let's proceed to step 10:
If we divide 6700 by 710, we get 9 and a remainder of 310.
The next digit of our result is 9. 
Result so far: 29568.89
If we subtract 6390 from 6700, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 11:
The number 710 fits into 3100 4 times, leaving a remainder of 260.
The number 4 becomes the next digit in our result. 
Result so far: 29568.894
The remainder is 260 after subtracting 2840 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 12:
The number 710 fits into 2600 3 times, leaving a remainder of 470.
The number 3 becomes the next digit in our result. 
Result so far: 29568.8943
Subtract 2130 from 2600 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 13:
The number 710 fits into 4700 6 times, leaving a remainder of 440.
The number 6 becomes the next digit in our result. 
Result so far: 29568.89436
The remainder is 440 after subtracting 4260 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 14:
710 goes into 4400 6 times with a remainder of 140.
Put 6 as the next digit of the answer. 
Result so far: 29568.894366
Subtracting 4260 from 4400 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

In conclusion, the division gives 29568.894366 with a balance of 1.4e-05.
