Let's divide 943736 by 3
We're looking to find how many times 3 goes into 943736.

On to step 1:
When dividing 9 by 3, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 9 from 9, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 3

Going ahead to step 2:
If we divide 4 by 3, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 3 from 4 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 3

Advancing to step 3:
3 can be fit into 13 4 times, resulting in a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 314.0
The remainder is 1 after subtracting 12 from 13.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 3

On to step 4:
If we divide 17 by 3, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 3145.0
Subtract 15 from 17 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 3

Advancing to step 5:
23 divided by 3 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 31457.0
If we take 21 away from 23, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 3

Advancing to step 6:
The number 3 fits into 26 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 314578.0
Deduct 24 from 26 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 314578.6
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
20 divided by 3 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 314578.66
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 314578.66, with a leftover of 0.002.
