263446 ÷ 20 
We want to divide 263446 by 20.

Advancing to step 1:
If we divide 2 by 20, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 20

Let's proceed to step 2:
26 divided by 20 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 20 from 26 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 20

Advancing to step 3:
If we divide 63 by 20, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 60 from 63, we get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 20

Let's proceed to step 4:
When dividing 34 by 20, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
The remainder is 14 after subtracting 20 from 34.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 20

Let's proceed to step 5:
20 goes into 144 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 1317.0
If we subtract 140 from 144, we get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 20

Moving on to step 6:
The number 20 fits into 46 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 13172.0
Subtract 40 from 46 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
If we divide 60 by 20, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 13172.3
If we subtract 60 from 60, 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.

On to step 8:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13172.3
The remainder is 0 after subtracting 0 from 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.
The next digit of our result is 0. 
Result so far: 13172.3
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.

Our division results in 13172.3 with a remaining 0.0.
