We're dividing 354112 by 20 
We want to divide 354112 by 20.

Moving on to step 1:
If we divide 3 by 20, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 20

Going ahead to step 2:
The number 20 fits into 35 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 20 away from 35, we end up with 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 20

On to step 3:
The number 20 fits into 154 7 times, leaving a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 140 from 154, we get 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 20

Step 4:
20 goes into 141 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
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

On to step 5:
20 can be fit into 11 0 times, resulting in a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 1770.0
If we take 0 away from 11, we end up with 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 20

On to step 6:
20 goes into 112 5 times with a remainder of 12.
The next digit of our result is 5. 
Result so far: 17705.0
Subtract 100 from 112 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
The number 20 fits into 120 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 17705.6
Deduct 120 from 120 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.

Going ahead to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17705.6
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.

Let's proceed to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17705.6
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.

The final result is 17705.6 with a remainder of 0.0.
