688150 ÷ 23 
We want to figure out the number of times 688150 can be divided by 23.

Advancing to step 1:
The number 23 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 23

Going ahead to step 2:
When dividing 68 by 23, we get 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 46 from 68, we get 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 23

Moving on to step 3:
228 divided by 23 is 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtract 207 from 228 to get 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 23

Advancing to step 4:
211 divided by 23 is 9 with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 299.0
The remainder is 4 after subtracting 207 from 211.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 23

Moving on to step 5:
45 divided by 23 is 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 2991.0
If we take 23 away from 45, we end up with 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 23

Going ahead to step 6:
The number 23 fits into 220 9 times, leaving a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 29919.0
The remainder is 13 after subtracting 207 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
If we divide 130 by 23, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 29919.5
Deduct 115 from 130 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
150 divided by 23 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 29919.56
Subtracting 138 from 150 leaves us 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.

Advancing to step 9:
If we divide 120 by 23, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 29919.565
Subtract 115 from 120 to 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.

Going ahead to step 10:
When dividing 50 by 23, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 29919.5652
If we take 46 away from 50, we end up 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 11:
23 can be fit into 40 1 times, resulting in a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 29919.56521
If we take 23 away from 40, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 12:
When dividing 170 by 23, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 29919.565217
Subtracting 161 from 170 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 29919.5652173
If we subtract 69 from 90, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
23 goes into 210 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 29919.56521739
Subtracting 207 from 210 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 29919.56521739 with a remaining 3e-09.
