We divide 16720330 by 23
We're looking to find how many times 23 goes into 16720330.

Moving on to step 1:
If we divide 1 by 23, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 23

Going ahead to step 2:
The number 23 fits into 16 0 times, leaving a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 23

On to step 3:
The number 23 fits into 167 7 times, leaving a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 161 away from 167, we end up with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 23

On to step 4:
If we divide 62 by 23, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we subtract 46 from 62, we get 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 23

On to step 5:
If we divide 160 by 23, we get 6 and a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 726.0
If we subtract 138 from 160, we get 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 23

Going ahead to step 6:
23 can be fit into 223 9 times, resulting in a remainder of 16.
The next digit of our result is 9. 
Result so far: 7269.0
Deduct 207 from 223 and we're left with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 23

Moving on to step 7:
If we divide 163 by 23, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 72697.0
Subtract 161 from 163 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 23

Advancing to step 8:
23 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 726970.0
If we subtract 0 from 20, we 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.

Let's proceed to step 9:
23 can be fit into 200 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 726970.8
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.

On to step 10:
23 goes into 160 6 times with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 726970.86
If we subtract 138 from 160, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
If we divide 220 by 23, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 726970.869
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.

Advancing to step 12:
130 divided by 23 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 726970.8695
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.

Let's proceed to step 13:
23 goes into 150 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 726970.86956
Subtracting 138 from 150 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
23 goes into 120 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 726970.869565
The remainder is 5 after subtracting 115 from 120.
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 15:
50 divided by 23 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 726970.8695652
If we take 46 away from 50, we end up 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 16:
If we divide 40 by 23, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 726970.86956521
Subtract 23 from 40 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 726970.86956521 and a remainder of 1.7e-08.
