We look at the division of 443612 by 3 
We want to divide 443612 by 3.

Advancing to step 1:
3 goes into 4 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 1 after subtracting 3 from 4.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 3

Step 2:
If we divide 14 by 3, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 12 from 14 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 3

Step 3:
The number 3 fits into 23 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 147.0
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

Moving on to step 4:
If we divide 26 by 3, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1478.0
Deduct 24 from 26 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 3

Advancing to step 5:
If we divide 21 by 3, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 14787.0
Subtract 21 from 21 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 3

Going ahead to step 6:
2 divided by 3 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 147870.0
If we subtract 0 from 2, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 147870.6
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.

Going ahead to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 147870.66
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 147870.66 with a remaining 0.002.
