623375 ÷ 20 
We're looking to find how many times 20 goes into 623375.

Going ahead to step 1:
When dividing 6 by 20, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 20

Moving on to step 2:
20 goes into 62 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 60 from 62 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 20

Advancing to step 3:
If we divide 23 by 20, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we take 20 away from 23, we end up with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 20

Going ahead to step 4:
33 divided by 20 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 311.0
Subtracting 20 from 33 leaves us with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 20

Advancing to step 5:
If we divide 137 by 20, we get 6 and a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 3116.0
If we subtract 120 from 137, we get 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 20

Let's proceed to step 6:
175 divided by 20 is 8 with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 31168.0
If we subtract 160 from 175, 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 7:
150 divided by 20 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 31168.7
Subtract 140 from 150 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 31168.75
Deduct 100 from 100 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31168.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31168.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 31168.75, with a leftover of 0.0.
