We divide 416946 by 3
We want to divide 416946 by 3.

Let's proceed to step 1:
3 can be fit into 4 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 3 from 4 to get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 3

Step 2:
3 can be fit into 11 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 9 from 11, we get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 3

Going ahead to step 3:
If we divide 26 by 3, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 138.0
Subtracting 24 from 26 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 3

Moving on to step 4:
3 goes into 29 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 1389.0
If we take 27 away from 29, we end up with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 3

Advancing 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: 13898.0
If we subtract 24 from 24, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 3

Advancing to step 6:
3 can be fit into 6 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 138982.0
Deduct 6 from 6 and we're left with 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 7:
0 divided by 3 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 138982.0
Deduct 0 from 0 and we're left with 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:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 138982.0
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.

The final outcome is 138982.0, with a leftover of 0.0.
