We're dividing 357335 by 20 
We're looking to find how many times 20 goes into 357335.

Step 1:
20 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 20

Moving on to step 2:
20 goes into 35 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 15 after subtracting 20 from 35.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 20

Advancing to step 3:
20 can be fit into 157 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 140 from 157 leaves us with 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 20

Advancing to step 4:
When dividing 173 by 20, we get 8 with a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 178.0
The remainder is 13 after subtracting 160 from 173.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 20

Step 5:
The number 20 fits into 133 6 times, leaving a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 1786.0
Deduct 120 from 133 and we're left with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 20

Advancing to step 6:
135 divided by 20 is 6 with a remainder of 15.
The next digit of our result is 6. 
Result so far: 17866.0
The remainder is 15 after subtracting 120 from 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
If we divide 150 by 20, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 17866.7
If we subtract 140 from 150, we 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.

Advancing to step 8:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 17866.75
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:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17866.75
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:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17866.75
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.

The final outcome is 17866.75, with a leftover of 0.0.
