737643 divided by 23 
The aim is to understand the frequency of 23 in 737643.

Moving on to step 1:
If we divide 7 by 23, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 23

Going ahead to step 2:
73 divided by 23 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 69 from 73 leaves us with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 23

Let's proceed to step 3:
If we divide 47 by 23, we get 2 and a remainder of 1.
The next digit of our result is 2. 
Result so far: 32.0
If we take 46 away from 47, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 23

Step 4:
If we divide 16 by 23, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 320.0
Deduct 0 from 16 and we're left with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 23

Going ahead to step 5:
The number 23 fits into 164 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 3207.0
Deduct 161 from 164 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 23

Moving on to step 6:
33 divided by 23 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 32071.0
If we take 23 away from 33, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
23 can be fit into 100 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 32071.4
Subtracting 92 from 100 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
The number 23 fits into 80 3 times, leaving a remainder of 11.
The next digit of our result is 3. 
Result so far: 32071.43
Subtracting 69 from 80 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
23 can be fit into 110 4 times, resulting in a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 32071.434
Subtracting 92 from 110 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
23 can be fit into 180 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 32071.4347
If we subtract 161 from 180, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 11:
If we divide 190 by 23, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 32071.43478
Subtract 184 from 190 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
When dividing 60 by 23, we get 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 32071.434782
Subtracting 46 from 60 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 13:
The number 23 fits into 140 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 32071.4347826
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
23 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 32071.4347826
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 32071.4347826 with a remainder of 2e-08.
