20389353 ÷ 30 
We want to divide 20389353 by 30.

Step 1:
30 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 30

On to step 2:
30 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 30

Step 3:
30 goes into 203 6 times with a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 180 away from 203, we end up with 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 30

Advancing to step 4:
The number 30 fits into 238 7 times, leaving a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 67.0
If we subtract 210 from 238, we get 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 30

Moving on to step 5:
If we divide 289 by 30, we get 9 and a remainder of 19.
The next digit of our result is 9. 
Result so far: 679.0
If we subtract 270 from 289, we get 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 30

On to step 6:
193 divided by 30 is 6 with a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 6796.0
If we take 180 away from 193, we end up with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 30

Let's proceed to step 7:
30 can be fit into 135 4 times, resulting in a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 67964.0
The remainder is 15 after subtracting 120 from 135.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 30

Let's proceed to step 8:
The number 30 fits into 153 5 times, leaving a remainder of 3.
The next digit of our result is 5. 
Result so far: 679645.0
If we take 150 away from 153, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
30 divided by 30 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 679645.1
Deduct 30 from 30 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.

Going ahead to step 10:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 679645.1
If we subtract 0 from 0, we 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 11:
0 divided by 30 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 679645.1
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.

The final result is 679645.1 with a remainder of 0.0.
