We divide 361357 by 20
We want to figure out the number of times 361357 can be divided by 20.

On to step 1:
20 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 20

Step 2:
20 can be fit into 36 1 times, resulting in a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 20 from 36 leaves us with 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 20

Advancing to step 3:
161 divided by 20 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 160 from 161, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 20

Going ahead to step 4:
20 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 180.0
If we take 0 away from 13, we end up with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 20

Let's proceed to step 5:
20 goes into 135 6 times with a remainder of 15.
The next digit of our result is 6. 
Result so far: 1806.0
The remainder is 15 after subtracting 120 from 135.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 20

Advancing to step 6:
If we divide 157 by 20, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 18067.0
Subtracting 140 from 157 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
The number 20 fits into 170 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 18067.8
The remainder is 10 after subtracting 160 from 170.
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:
When dividing 100 by 20, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 18067.85
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18067.85
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.

Step 10:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18067.85
The remainder is 0 after subtracting 0 from 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 result is 18067.85 with a remainder of 0.0.
