749386 divided by 3 
We're looking to find how many times 3 goes into 749386.

Going ahead to step 1:
If we divide 7 by 3, we get 2 and a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 6 from 7 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

Moving on to step 2:
3 can be fit into 14 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we subtract 12 from 14, we get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 3

On to step 3:
3 goes into 29 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 249.0
The remainder is 2 after subtracting 27 from 29.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 3

Moving on to step 4:
The number 3 fits into 23 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 2497.0
Subtracting 21 from 23 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 3

Step 5:
If we divide 28 by 3, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 24979.0
The remainder is 1 after subtracting 27 from 28.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 3

On to step 6:
3 goes into 16 5 times with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 249795.0
Subtracting 15 from 16 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
3 goes into 10 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 249795.3
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 249795.33
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 249795.33 with a remaining 0.001.
