We're dividing 357703 by 20 
We want to figure out the number of times 357703 can be divided by 20.

Advancing 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
If we subtract 0 from 3, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 20

On to step 2:
When dividing 35 by 20, we get 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 20 from 35 to get 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 20

Step 3:
157 divided by 20 is 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 140 from 157, we get 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 20

Advancing to step 4:
The number 20 fits into 177 8 times, leaving a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 178.0
The remainder is 17 after subtracting 160 from 177.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 20

Step 5:
The number 20 fits into 170 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 1788.0
If we take 160 away from 170, we end up with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 20

Step 6:
When dividing 103 by 20, we get 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 17885.0
If we subtract 100 from 103, we 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.

Step 7:
20 goes into 30 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 17885.1
Deduct 20 from 30 and we're left 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.

Moving on to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 17885.15
Subtracting 100 from 100 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.

Advancing to step 9:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17885.15
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.

Step 10:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17885.15
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.

The final outcome is 17885.15, with a leftover of 0.0.
