We look at the division of 363874 by 20 
We want to figure out the number of times 363874 can be divided by 20.

On to step 1:
When dividing 3 by 20, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 20

Moving on to step 2:
When dividing 36 by 20, we get 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 16 after subtracting 20 from 36.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 20

On to step 3:
If we divide 163 by 20, we get 8 and a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 160 from 163 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 20

Going ahead to step 4:
If we divide 38 by 20, we get 1 and a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 181.0
If we subtract 20 from 38, we get 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 20

Going ahead to step 5:
20 goes into 187 9 times with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 1819.0
Subtracting 180 from 187 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 20

On to step 6:
When dividing 74 by 20, we get 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 18193.0
Deduct 60 from 74 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
140 divided by 20 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 18193.7
Subtract 140 from 140 to 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.

Moving on to step 8:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18193.7
If we take 0 away from 0, we end up 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:
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: 18193.7
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 quotient of the division is 18193.7, and the remainder is 0.0.
