We're dividing 307743 by 3 
We want to divide 307743 by 3.

On to step 1:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 0 after subtracting 3 from 3.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 3

Moving on to step 2:
When dividing 0 by 3, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 0 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 3

Moving on to step 3:
3 goes into 7 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtract 6 from 7 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 3

On to step 4:
When dividing 17 by 3, we get 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 1025.0
If we subtract 15 from 17, we get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 3

Moving on to step 5:
24 divided by 3 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 10258.0
The remainder is 0 after subtracting 24 from 24.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 3

Going ahead to step 6:
3 goes into 3 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 102581.0
The remainder is 0 after subtracting 3 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
0 divided by 3 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 102581.0
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 8:
If we divide 0 by 3, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 102581.0
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 102581.0 with a remaining 0.0.
