Let's divide 77621 by 30
Our goal is to divide 77621 by 30.

Let's proceed to step 1:
When dividing 7 by 30, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 30

On to step 2:
30 goes into 77 2 times with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 60 from 77 to get 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 30

Advancing to step 3:
If we divide 176 by 30, we get 5 and a remainder of 26.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 150 from 176 and we're left with 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 30

Let's proceed to step 4:
30 can be fit into 262 8 times, resulting in a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 258.0
Subtract 240 from 262 to get 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 30

Moving on to step 5:
221 divided by 30 is 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 2587.0
If we take 210 away from 221, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 6:
If we divide 110 by 30, we get 3 and a remainder of 20.
The next digit of our result is 3. 
Result so far: 2587.3
Subtracting 90 from 110 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 2587.36
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
30 goes into 200 6 times with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 2587.366
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 2587.366 with a balance of 0.002.
