We look at the division of 64230020 by 723 
The aim is to understand the frequency of 723 in 64230020.

Moving on to step 1:
The number 723 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 723

Advancing to step 2:
The number 723 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Include the next digit (2) from the dividend after 64, then repeat: 642 / 723

Let's proceed to step 3:
642 divided by 723 is 0 with a remainder of 642.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 642 after subtracting 0 from 642.
Grab the next digit (3) from the dividend, add it to 642, then carry on: 6423 / 723

Moving on to step 4:
6423 divided by 723 is 8 with a remainder of 639.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 639 after subtracting 5784 from 6423.
Bring next digit (0) of the dividend behind the 639 and repeat the process: 6390 / 723

Step 5:
If we divide 6390 by 723, we get 8 and a remainder of 606.
The next digit of our result is 8. 
Result so far: 88.0
If we subtract 5784 from 6390, we get 606.
Bring next digit (0) of the dividend behind the 606 and repeat the process: 6060 / 723

Moving on to step 6:
6060 divided by 723 is 8 with a remainder of 276.
Use 8 as the next digit of our solution. 
Result so far: 888.0
If we take 5784 away from 6060, we end up with 276.
Include the next digit (2) from the dividend after 276, then repeat: 2762 / 723

On to step 7:
When dividing 2762 by 723, we get 3 with a remainder of 593.
Use 3 as the next digit of our solution. 
Result so far: 8883.0
If we take 2169 away from 2762, we end up with 593.
Include the next digit (0) from the dividend after 593, then repeat: 5930 / 723

On to step 8:
5930 divided by 723 is 8 with a remainder of 146.
Record the quotient 8 as the next digit in the result. 
Result so far: 88838.0
Subtracting 5784 from 5930 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 9:
723 can be fit into 1460 2 times, resulting in a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 88838.2
Subtracting 1446 from 1460 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.

Moving on to step 10:
The number 723 fits into 140 0 times, leaving a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 88838.2
Subtracting 0 from 140 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.

Let's proceed to step 11:
The number 723 fits into 1400 1 times, leaving a remainder of 677.
The number 1 becomes the next digit in our result. 
Result so far: 88838.201
Subtract 723 from 1400 to get 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

On to step 12:
723 can be fit into 6770 9 times, resulting in a remainder of 263.
Record the quotient 9 as the next digit in the result. 
Result so far: 88838.2019
The remainder is 263 after subtracting 6507 from 6770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 13:
723 goes into 2630 3 times with a remainder of 461.
Write down 3 as next digit of the result. 
Result so far: 88838.20193
If we subtract 2169 from 2630, we get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Step 14:
723 goes into 4610 6 times with a remainder of 272.
The number 6 becomes the next digit in our result. 
Result so far: 88838.201936
Deduct 4338 from 4610 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 15:
If we divide 2720 by 723, we get 3 and a remainder of 551.
The number 3 becomes the next digit in our result. 
Result so far: 88838.2019363
Subtract 2169 from 2720 to get 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Going ahead to step 16:
723 goes into 5510 7 times with a remainder of 449.
Put 7 as the next digit of the answer. 
Result so far: 88838.20193637
Deduct 5061 from 5510 and we're left with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

The final result is 88838.20193637 with a remainder of 4.49e-07.
