We look at the division of 391670 by 23 
Let's see how many times 23 fits into 391670.

Step 1:
23 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 23

Going ahead to step 2:
23 goes into 39 1 times with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 23 from 39 leaves us with 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 23

Let's proceed to step 3:
23 can be fit into 161 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 17.0
The remainder is 0 after subtracting 161 from 161.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 23

Moving on to step 4:
6 divided by 23 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 170.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 23

Step 5:
If we divide 67 by 23, we get 2 and a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 1702.0
Deduct 46 from 67 and we're left with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 23

Let's proceed to step 6:
23 can be fit into 210 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 17029.0
If we take 207 away from 210, 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 7:
When dividing 30 by 23, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 17029.1
The remainder is 7 after subtracting 23 from 30.
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 8:
23 goes into 70 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 17029.13
The remainder is 1 after subtracting 69 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
23 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 17029.13
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
If we divide 100 by 23, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 17029.1304
If we subtract 92 from 100, we get 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 11:
If we divide 80 by 23, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 17029.13043
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.

Going ahead to step 12:
When dividing 110 by 23, we get 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 17029.130434
The remainder is 18 after subtracting 92 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
If we divide 180 by 23, we get 7 and a remainder of 19.
The next digit of our result is 7. 
Result so far: 17029.1304347
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
23 goes into 190 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 17029.13043478
Subtract 184 from 190 to 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.

The quotient of the division is 17029.13043478, and the remainder is 6e-09.
