We're dividing 366198 by 20 
Let's see how many times 20 fits into 366198.

Moving on to step 1:
3 divided by 20 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 20

Moving on to step 2:
20 can be fit into 36 1 times, resulting in a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 20 from 36, we get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 20

Advancing to step 3:
The number 20 fits into 166 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 160 from 166 to get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 20

Step 4:
If we divide 61 by 20, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 183.0
If we subtract 60 from 61, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 20

Step 5:
20 goes into 19 0 times with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 1830.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 20

Step 6:
20 can be fit into 198 9 times, resulting in a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 18309.0
If we subtract 180 from 198, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
180 divided by 20 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 18309.9
Subtract 180 from 180 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.

Advancing to step 8:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18309.9
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 9:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18309.9
Deduct 0 from 0 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.

The final outcome is 18309.9, with a leftover of 0.0.
