We're dividing 901149 by 3 
We want to divide 901149 by 3.

Step 1:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 0 after subtracting 9 from 9.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 3

Going ahead to step 2:
If we divide 0 by 3, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 0 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Step 3:
If we divide 1 by 3, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 300.0
If we subtract 0 from 1, we get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 3

On to step 4:
When dividing 11 by 3, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3003.0
The remainder is 2 after subtracting 9 from 11.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 3

Let's proceed to step 5:
3 can be fit into 24 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 30038.0
Deduct 24 from 24 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 3

Let's proceed to step 6:
3 goes into 9 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 300383.0
Subtract 9 from 9 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.

Advancing to step 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 300383.0
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.

Moving on to step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 300383.0
Subtract 0 from 0 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.

Our division results in 300383.0 with a remaining 0.0.
