19398008 ÷ 3 
We want to divide 19398008 by 3.

Let's proceed to step 1:
3 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 3

Let's proceed to step 2:
If we divide 19 by 3, we get 6 and a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 18 from 19 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 3

Going ahead to step 3:
The number 3 fits into 13 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtract 12 from 13 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 3

Moving on to step 4:
3 can be fit into 19 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 646.0
If we take 18 away from 19, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Let's proceed to step 5:
If we divide 18 by 3, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 6466.0
Deduct 18 from 18 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 3

Advancing to step 6:
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: 64660.0
Subtract 0 from 0 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 3

Moving on to step 7:
3 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 646600.0
If we take 0 away from 0, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

On to step 8:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 6466002.0
Subtract 6 from 8 to 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.

Moving on to step 9:
When dividing 20 by 3, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 6466002.6
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 10:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 6466002.66
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.

Our division results in 6466002.66 with a remaining 0.002.
