334943 ÷ 20 
We're looking to find how many times 20 goes into 334943.

Advancing to step 1:
3 divided by 20 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 20

On to step 2:
20 can be fit into 33 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 13 after subtracting 20 from 33.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 20

Let's proceed to step 3:
The number 20 fits into 134 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 120 away from 134, we end up with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 20

Let's proceed to step 4:
149 divided by 20 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 167.0
If we take 140 away from 149, we end up with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 20

On to step 5:
If we divide 94 by 20, we get 4 and a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 1674.0
Subtract 80 from 94 to get 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 20

Moving on to step 6:
When dividing 143 by 20, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 16747.0
If we subtract 140 from 143, 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.

Let's proceed to step 7:
If we divide 30 by 20, we get 1 and a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 16747.1
Subtracting 20 from 30 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.

Advancing to step 8:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 16747.15
If we take 100 away from 100, 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.

Going ahead to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 16747.15
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.

Advancing to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16747.15
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.

Our division results in 16747.15 with a remaining 0.0.
