21083935 ÷ 30 
We want to divide 21083935 by 30.

Let's proceed to step 1:
When dividing 2 by 30, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 30

Advancing to step 2:
When dividing 21 by 30, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 30

Let's proceed to step 3:
If we divide 210 by 30, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 210 away from 210, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 30

Advancing to step 4:
8 divided by 30 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 70.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 30

Let's proceed to step 5:
30 goes into 83 2 times with a remainder of 23.
The next digit of our result is 2. 
Result so far: 702.0
Subtract 60 from 83 to get 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 30

Moving on to step 6:
30 goes into 239 7 times with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 7027.0
If we subtract 210 from 239, we get 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 30

Advancing to step 7:
293 divided by 30 is 9 with a remainder of 23.
The next digit of our result is 9. 
Result so far: 70279.0
The remainder is 23 after subtracting 270 from 293.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 30

On to step 8:
The number 30 fits into 235 7 times, leaving a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 702797.0
If we take 210 away from 235, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
250 divided by 30 is 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 702797.8
If we take 240 away from 250, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 702797.83
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
When dividing 100 by 30, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 702797.833
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 702797.833, with a leftover of 0.001.
