We look at the division of 689736 by 23 
We're looking to find how many times 23 goes into 689736.

On to step 1:
23 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 23

Let's proceed to step 2:
If we divide 68 by 23, we get 2 and a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 46 away from 68, we end up with 22.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 23

Moving on to step 3:
229 divided by 23 is 9 with a remainder of 22.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 207 from 229 to get 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 23

Step 4:
When dividing 227 by 23, we get 9 with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 299.0
Subtract 207 from 227 to get 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 23

On to step 5:
The number 23 fits into 203 8 times, leaving a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 2998.0
Subtract 184 from 203 to get 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 23

Advancing to step 6:
The number 23 fits into 196 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 29988.0
If we subtract 184 from 196, we get 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 7:
23 can be fit into 120 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 29988.5
Deduct 115 from 120 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
If we divide 50 by 23, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 29988.52
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.

Moving on to step 9:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 29988.521
The remainder is 17 after subtracting 23 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
The number 23 fits into 170 7 times, leaving a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 29988.5217
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.

On to step 11:
23 goes into 90 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 29988.52173
The remainder is 21 after subtracting 69 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
The number 23 fits into 210 9 times, leaving a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 29988.521739
The remainder is 3 after subtracting 207 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
23 can be fit into 30 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 29988.5217391
Deduct 23 from 30 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 14:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 29988.52173913
Subtracting 69 from 70 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 29988.52173913, with a leftover of 1e-09.
