We divide 681788 by 23
The aim is to understand the frequency of 23 in 681788.

Moving on to step 1:
If we divide 6 by 23, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 23

Advancing to step 2:
The number 23 fits into 68 2 times, leaving a remainder of 22.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 46 from 68 to get 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 23

Step 3:
The number 23 fits into 221 9 times, leaving a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtracting 207 from 221 leaves us with 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 23

On to step 4:
When dividing 147 by 23, we get 6 with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 296.0
Deduct 138 from 147 and we're left with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 23

Advancing to step 5:
When dividing 98 by 23, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 2964.0
Deduct 92 from 98 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 23

On to step 6:
If we divide 68 by 23, we get 2 and a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 29642.0
If we subtract 46 from 68, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
23 goes into 220 9 times with a remainder of 13.
The next digit of our result is 9. 
Result so far: 29642.9
If we subtract 207 from 220, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
23 can be fit into 130 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 29642.95
If we subtract 115 from 130, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
150 divided by 23 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 29642.956
If we take 138 away from 150, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
23 can be fit into 120 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 29642.9565
If we subtract 115 from 120, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
The number 23 fits into 50 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 29642.95652
Subtracting 46 from 50 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 29642.956521
If we subtract 23 from 40, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 13:
23 goes into 170 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 29642.9565217
The remainder is 9 after subtracting 161 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
23 goes into 90 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 29642.95652173
If we take 69 away from 90, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 29642.95652173 with a remaining 2.1e-08.
