We're dividing 21771640 by 30 
We want to divide 21771640 by 30.

Step 1:
2 divided by 30 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 30

Advancing to step 2:
When dividing 21 by 30, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 30

Advancing to step 3:
If we divide 217 by 30, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 210 away from 217, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 30

Advancing to step 4:
30 can be fit into 77 2 times, resulting in a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we take 60 away from 77, we end up with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 30

Moving on to step 5:
If we divide 171 by 30, we get 5 and a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 725.0
If we take 150 away from 171, we end up with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 30

Step 6:
The number 30 fits into 216 7 times, leaving a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 7257.0
The remainder is 6 after subtracting 210 from 216.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 30

Advancing to step 7:
64 divided by 30 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 72572.0
Deduct 60 from 64 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 30

Going ahead to step 8:
40 divided by 30 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 725721.0
Deduct 30 from 40 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.

Advancing to step 9:
30 can be fit into 100 3 times, resulting in a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 725721.3
Subtracting 90 from 100 leaves us 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.

Advancing to step 10:
30 goes into 100 3 times with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 725721.33
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.

Our division results in 725721.33 with a remaining 0.01.
