159640 divided by 23 
We want to divide 159640 by 23.

Advancing to step 1:
If we divide 1 by 23, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 23

Going ahead to step 2:
15 divided by 23 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 23

Step 3:
When dividing 159 by 23, we get 6 with a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 138 from 159 and we're left with 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 23

Advancing to step 4:
If we divide 216 by 23, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
If we subtract 207 from 216, we get 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 23

Moving on to step 5:
The number 23 fits into 94 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 694.0
The remainder is 2 after subtracting 92 from 94.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 23

Going ahead to step 6:
23 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 6940.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
When dividing 200 by 23, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 6940.8
Subtracting 184 from 200 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 6940.86
If we take 138 away from 160, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
23 can be fit into 220 9 times, resulting in a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 6940.869
Deduct 207 from 220 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
130 divided by 23 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 6940.8695
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.

Advancing to step 11:
23 goes into 150 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 6940.86956
Subtract 138 from 150 to 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 12:
120 divided by 23 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 6940.869565
If we take 115 away from 120, we end up 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.

Advancing to step 13:
When dividing 50 by 23, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 6940.8695652
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 14:
23 goes into 40 1 times with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 6940.86956521
Deduct 23 from 40 and we're left 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.

In conclusion, the division gives 6940.86956521 with a balance of 1.7e-08.
