23643 ÷ 8 
Let's see how many times 8 fits into 23643.

Moving on to step 1:
2 divided by 8 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 8

Going ahead to step 2:
If we divide 23 by 8, we get 2 and a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 7 after subtracting 16 from 23.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 8

On to step 3:
8 can be fit into 76 9 times, resulting in a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we take 72 away from 76, we end up with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 8

On to step 4:
8 goes into 44 5 times with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 295.0
Subtracting 40 from 44 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 8

Advancing to step 5:
When dividing 43 by 8, we get 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 2955.0
If we take 40 away from 43, we end up 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.

Going ahead to step 6:
The number 8 fits into 30 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 2955.3
Subtracting 24 from 30 leaves us with 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 7:
When dividing 60 by 8, we get 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 2955.37
Deduct 56 from 60 and we're left 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.

Step 8:
If we divide 40 by 8, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2955.375
If we take 40 away from 40, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2955.375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2955.375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 2955.375 with a remainder of 0.0.
