We divide 1201842 by 3
We're looking to find how many times 3 goes into 1201842.

Step 1:
3 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 3

Step 2:
If we divide 12 by 3, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 12 from 12 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

Step 3:
When dividing 0 by 3, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we subtract 0 from 0, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 3

On to step 4:
When dividing 1 by 3, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 400.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

Step 5:
If we divide 18 by 3, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 4006.0
If we take 18 away from 18, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 3

Advancing to step 6:
If we divide 4 by 3, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 40061.0
Subtracting 3 from 4 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 3

Step 7:
12 divided by 3 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 400614.0
Subtract 12 from 12 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.

On to step 8:
3 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 400614.0
Subtracting 0 from 0 leaves us 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.

Going ahead to step 9:
If we divide 0 by 3, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 400614.0
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 result is 400614.0 with a remainder of 0.0.
