We look at the division of 21759342 by 30 
Let's see how many times 30 fits into 21759342.

Advancing to step 1:
When dividing 2 by 30, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 30

Going ahead to step 2:
When dividing 21 by 30, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 30

Let's proceed to step 3:
217 divided by 30 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 210 from 217, we get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 30

Let's proceed to step 4:
75 divided by 30 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Subtracting 60 from 75 leaves us with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 30

Step 5:
159 divided by 30 is 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 725.0
Subtract 150 from 159 to get 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 30

On to step 6:
When dividing 93 by 30, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 7253.0
Subtract 90 from 93 to get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 30

Let's proceed to step 7:
If we divide 34 by 30, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 72531.0
Deduct 30 from 34 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 30

Let's proceed to step 8:
30 goes into 42 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 725311.0
Subtract 30 from 42 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
When dividing 120 by 30, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 725311.4
If we take 120 away from 120, we end up 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.

Advancing to step 10:
30 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 725311.4
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.

Going ahead to step 11:
0 divided by 30 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 725311.4
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.

Our division results in 725311.4 with a remaining 0.0.
