65430945 ÷ 723 
The aim is to understand the frequency of 723 in 65430945.

Moving on to step 1:
If we divide 6 by 723, we get 0 and 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.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 723

Advancing to step 2:
723 can be fit into 65 0 times, resulting in a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Bring next digit (4) of the dividend behind the 65 and repeat the process: 654 / 723

Let's proceed to step 3:
The number 723 fits into 654 0 times, leaving a remainder of 654.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 654, we end up with 654.
Include the next digit (3) from the dividend after 654, then repeat: 6543 / 723

Step 4:
When dividing 6543 by 723, we get 9 with a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 6507 from 6543 to get 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 723

Let's proceed to step 5:
360 divided by 723 is 0 with a remainder of 360.
The next digit of our result is 0. 
Result so far: 90.0
Deduct 0 from 360 and we're left with 360.
Take the next digit (9) from the dividend and append it to 360, then repeat: 3609 / 723

Going ahead to step 6:
723 goes into 3609 4 times with a remainder of 717.
Record the quotient 4 as the next digit in the result. 
Result so far: 904.0
Subtracting 2892 from 3609 leaves us with 717.
Include the next digit (4) from the dividend after 717, then repeat: 7174 / 723

Moving on to step 7:
723 can be fit into 7174 9 times, resulting in a remainder of 667.
Use 9 as the next digit of our solution. 
Result so far: 9049.0
If we subtract 6507 from 7174, we get 667.
Take the next digit (5) from the dividend and append it to 667, then repeat: 6675 / 723

Advancing to step 8:
When dividing 6675 by 723, we get 9 with a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 90499.0
If we take 6507 away from 6675, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 9:
1680 divided by 723 is 2 with a remainder of 234.
The number 2 becomes the next digit in our result. 
Result so far: 90499.2
The remainder is 234 after subtracting 1446 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 10:
2340 divided by 723 is 3 with a remainder of 171.
Put 3 as the next digit of the answer. 
Result so far: 90499.23
Deduct 2169 from 2340 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 11:
1710 divided by 723 is 2 with a remainder of 264.
Use 2 as the next digit of our solution. 
Result so far: 90499.232
Subtracting 1446 from 1710 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 12:
The number 723 fits into 2640 3 times, leaving a remainder of 471.
Write down 3 as next digit of the result. 
Result so far: 90499.2323
The remainder is 471 after subtracting 2169 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Step 13:
When dividing 4710 by 723, we get 6 with a remainder of 372.
Use 6 as the next digit of our solution. 
Result so far: 90499.23236
Subtract 4338 from 4710 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Let's proceed to step 14:
The number 723 fits into 3720 5 times, leaving a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 90499.232365
Subtracting 3615 from 3720 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 15:
1050 divided by 723 is 1 with a remainder of 327.
Write down 1 as next digit of the result. 
Result so far: 90499.2323651
The remainder is 327 after subtracting 723 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Let's proceed to step 16:
3270 divided by 723 is 4 with a remainder of 378.
The next digit of our result is 4. 
Result so far: 90499.23236514
If we subtract 2892 from 3270, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

The final outcome is 90499.23236514, with a leftover of 3.78e-07.
