372783 divided by 20 
We're looking to find how many times 20 goes into 372783.

Going ahead to step 1:
3 divided by 20 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 20

Going ahead to step 2:
If we divide 37 by 20, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 20 from 37 leaves us with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 20

Let's proceed to step 3:
20 can be fit into 172 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 18.0
If we take 160 away from 172, we end up with 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 20

On to step 4:
If we divide 127 by 20, we get 6 and a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 186.0
The remainder is 7 after subtracting 120 from 127.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 20

Advancing to step 5:
78 divided by 20 is 3 with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 1863.0
Subtract 60 from 78 to get 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 20

Going ahead to step 6:
183 divided by 20 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 18639.0
Subtract 180 from 183 to get 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 20, we get 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 18639.1
If we take 20 away from 30, 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.

Advancing to step 8:
100 divided by 20 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 18639.15
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.

Moving on to step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 18639.15
Subtracting 0 from 0 leaves us 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.

Step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18639.15
Subtracting 0 from 0 leaves us 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.

In conclusion, the division gives 18639.15 with a balance of 0.0.
