Let's divide 354115 by 20
We want to divide 354115 by 20.

On to step 1:
The number 20 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 20

Let's proceed to step 2:
20 can be fit into 35 1 times, resulting in a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 20 away from 35, we end up with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 20

Advancing to step 3:
The number 20 fits into 154 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 140 from 154 and we're left with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 20

Step 4:
20 goes into 141 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 177.0
Deduct 140 from 141 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 20

Let's proceed to step 5:
11 divided by 20 is 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 1770.0
Subtract 0 from 11 to get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 20

Going ahead to step 6:
20 can be fit into 115 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 17705.0
Subtract 100 from 115 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
When dividing 150 by 20, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 17705.7
Subtracting 140 from 150 leaves us 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:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 17705.75
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.

Moving on to step 9:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17705.75
Subtract 0 from 0 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 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17705.75
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.

After the division, we end up with 17705.75 and a remainder of 0.0.
