418345 divided by 3 
We want to figure out the number of times 418345 can be divided by 3.

On to step 1:
When dividing 4 by 3, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 3 from 4 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 3

Advancing to step 2:
The number 3 fits into 11 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 9 from 11, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 3

Step 3:
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: 139.0
Subtracting 27 from 28 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 3

Moving on to step 4:
The number 3 fits into 13 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 1394.0
Deduct 12 from 13 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 3

Let's proceed to step 5:
3 can be fit into 14 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 13944.0
Subtract 12 from 14 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 3

Advancing to step 6:
The number 3 fits into 25 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 139448.0
Subtracting 24 from 25 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.

Going ahead to step 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 139448.3
Subtracting 9 from 10 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 8:
10 divided by 3 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 139448.33
Deduct 9 from 10 and we're left 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.

In conclusion, the division gives 139448.33 with a balance of 0.001.
