180420 ÷ 23 
We want to divide 180420 by 23.

Going ahead to step 1:
1 divided by 23 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 23

Moving on to step 2:
18 divided by 23 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 23

Advancing to step 3:
The number 23 fits into 180 7 times, leaving a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 161 from 180 leaves us with 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 23

On to step 4:
When dividing 194 by 23, we get 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 78.0
Subtracting 184 from 194 leaves us with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 23

On to step 5:
23 goes into 102 4 times with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 784.0
If we take 92 away from 102, we end up with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 23

Advancing to step 6:
23 can be fit into 100 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 7844.0
The remainder is 8 after subtracting 92 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
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: 7844.3
If we take 69 away from 80, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
23 goes into 110 4 times with a remainder of 18.
The next digit of our result is 4. 
Result so far: 7844.34
Subtracting 92 from 110 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
If we divide 180 by 23, we get 7 and a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 7844.347
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:
190 divided by 23 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 7844.3478
The remainder is 6 after subtracting 184 from 190.
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:
The number 23 fits into 60 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 7844.34782
If we subtract 46 from 60, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
If we divide 140 by 23, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 7844.347826
The remainder is 2 after subtracting 138 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
20 divided by 23 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 7844.347826
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
23 goes into 200 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 7844.34782608
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 quotient of the division is 7844.34782608, and the remainder is 1.6e-08.
