We divide 4182961 by 3
We're looking to find how many times 3 goes into 4182961.

Going ahead to step 1:
3 goes into 4 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 3 from 4, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 3

Step 2:
3 can be fit into 11 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 9 from 11, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 3

On to step 3:
The number 3 fits into 28 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 139.0
The remainder is 1 after subtracting 27 from 28.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 3

Going ahead to step 4:
12 divided by 3 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 1394.0
If we subtract 12 from 12, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 3

Moving on to step 5:
When dividing 9 by 3, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 13943.0
If we subtract 9 from 9, we get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 3

Moving on to step 6:
6 divided by 3 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 139432.0
If we take 6 away from 6, we end up with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

Advancing to step 7:
3 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 1394320.0
Subtracting 0 from 1 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.

Step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 1394320.3
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.

On to step 9:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 1394320.33
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.

After the division, we end up with 1394320.33 and a remainder of 0.001.
