We're dividing 20728625 by 709 
The aim is to understand the frequency of 709 in 20728625.

On to step 1:
If we divide 2 by 709, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 709

Going ahead to step 2:
709 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 709

Advancing to step 3:
709 can be fit into 207 0 times, resulting in a remainder of 207.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 207 after subtracting 0 from 207.
Fetch the next digit (2) from the dividend, attach it to 207 and continue: 2072 / 709

Moving on to step 4:
709 goes into 2072 2 times with a remainder of 654.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1418 from 2072 to get 654.
Append the next digit (8) from the dividend to 654 and continue with: 6548 / 709

Step 5:
If we divide 6548 by 709, we get 9 and a remainder of 167.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
The remainder is 167 after subtracting 6381 from 6548.
Grab the next digit (6) from the dividend, add it to 167, then carry on: 1676 / 709

Moving on to step 6:
When dividing 1676 by 709, we get 2 with a remainder of 258.
The number 2 becomes the next digit in our result. 
Result so far: 292.0
Subtracting 1418 from 1676 leaves us with 258.
Fetch the next digit (2) from the dividend, attach it to 258 and continue: 2582 / 709

Let's proceed to step 7:
When dividing 2582 by 709, we get 3 with a remainder of 455.
Write down 3 as next digit of the result. 
Result so far: 2923.0
Deduct 2127 from 2582 and we're left with 455.
Grab the next digit (5) from the dividend, add it to 455, then carry on: 4555 / 709

Advancing to step 8:
When dividing 4555 by 709, we get 6 with a remainder of 301.
Put 6 as the next digit of the answer. 
Result so far: 29236.0
Subtracting 4254 from 4555 leaves us with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

On to step 9:
3010 divided by 709 is 4 with a remainder of 174.
Write down 4 as next digit of the result. 
Result so far: 29236.4
If we take 2836 away from 3010, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 10:
1740 divided by 709 is 2 with a remainder of 322.
Write down 2 as next digit of the result. 
Result so far: 29236.42
The remainder is 322 after subtracting 1418 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 11:
709 can be fit into 3220 4 times, resulting in a remainder of 384.
Use 4 as the next digit of our solution. 
Result so far: 29236.424
Subtract 2836 from 3220 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 12:
When dividing 3840 by 709, we get 5 with a remainder of 295.
Write down 5 as next digit of the result. 
Result so far: 29236.4245
If we subtract 3545 from 3840, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 13:
If we divide 2950 by 709, we get 4 and a remainder of 114.
The next digit of our result is 4. 
Result so far: 29236.42454
Deduct 2836 from 2950 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 14:
709 can be fit into 1140 1 times, resulting in a remainder of 431.
The number 1 becomes the next digit in our result. 
Result so far: 29236.424541
Subtracting 709 from 1140 leaves us with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

On to step 15:
709 can be fit into 4310 6 times, resulting in a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 29236.4245416
If we subtract 4254 from 4310, 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.

Let's proceed to step 16:
When dividing 560 by 709, we get 0 with a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 29236.4245416
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

In conclusion, the division gives 29236.4245416 with a balance of 5.6e-07.
