We look at the division of 321640 by 23 
We want to divide 321640 by 23.

Advancing to step 1:
23 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 23

On to step 2:
23 goes into 32 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 9 after subtracting 23 from 32.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 23

Moving on to step 3:
If we divide 91 by 23, we get 3 and a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 69 from 91 to get 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 23

On to step 4:
When dividing 226 by 23, we get 9 with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Subtract 207 from 226 to get 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 23

Advancing to step 5:
If we divide 194 by 23, we get 8 and a remainder of 10.
The next digit of our result is 8. 
Result so far: 1398.0
If we subtract 184 from 194, we get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 23

On to step 6:
If we divide 100 by 23, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 13984.0
If we take 92 away from 100, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
The number 23 fits into 80 3 times, leaving a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 13984.3
If we subtract 69 from 80, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
When dividing 110 by 23, we get 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 13984.34
Subtract 92 from 110 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
23 goes into 180 7 times with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 13984.347
Subtracting 161 from 180 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 10:
When dividing 190 by 23, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 13984.3478
If we subtract 184 from 190, we get 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 11:
When dividing 60 by 23, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 13984.34782
Deduct 46 from 60 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
The number 23 fits into 140 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 13984.347826
If we take 138 away from 140, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
When dividing 20 by 23, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 13984.347826
Subtracting 0 from 20 leaves us 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.

Moving on to step 14:
200 divided by 23 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 13984.34782608
Deduct 184 from 200 and we're left 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.

The final outcome is 13984.34782608, with a leftover of 1.6e-08.
