We're dividing 30821164 by 639 
We're looking to find how many times 639 goes into 30821164.

Moving on to step 1:
The number 639 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 639

Advancing to step 2:
30 divided by 639 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 639

Step 3:
When dividing 308 by 639, we get 0 with a remainder of 308.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 308 leaves us with 308.
Include the next digit (2) from the dividend after 308, then repeat: 3082 / 639

Let's proceed to step 4:
The number 639 fits into 3082 4 times, leaving a remainder of 526.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 2556 from 3082 and we're left with 526.
Bring next digit (1) of the dividend behind the 526 and repeat the process: 5261 / 639

Step 5:
The number 639 fits into 5261 8 times, leaving a remainder of 149.
Use 8 as the next digit of our solution. 
Result so far: 48.0
The remainder is 149 after subtracting 5112 from 5261.
Append the next digit (1) from the dividend to 149 and continue with: 1491 / 639

Step 6:
If we divide 1491 by 639, we get 2 and a remainder of 213.
Put 2 as the next digit of the answer. 
Result so far: 482.0
Subtracting 1278 from 1491 leaves us with 213.
Append the next digit (6) from the dividend to 213 and continue with: 2136 / 639

Advancing to step 7:
639 goes into 2136 3 times with a remainder of 219.
Use 3 as the next digit of our solution. 
Result so far: 4823.0
If we subtract 1917 from 2136, we get 219.
Bring next digit (4) of the dividend behind the 219 and repeat the process: 2194 / 639

Step 8:
When dividing 2194 by 639, we get 3 with a remainder of 277.
Record the quotient 3 as the next digit in the result. 
Result so far: 48233.0
Subtracting 1917 from 2194 leaves us with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Going ahead to step 9:
The number 639 fits into 2770 4 times, leaving a remainder of 214.
Record the quotient 4 as the next digit in the result. 
Result so far: 48233.4
The remainder is 214 after subtracting 2556 from 2770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 10:
If we divide 2140 by 639, we get 3 and a remainder of 223.
Put 3 as the next digit of the answer. 
Result so far: 48233.43
The remainder is 223 after subtracting 1917 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Moving on to step 11:
If we divide 2230 by 639, we get 3 and a remainder of 313.
Put 3 as the next digit of the answer. 
Result so far: 48233.433
Subtract 1917 from 2230 to get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

In conclusion, the division gives 48233.433 with a balance of 0.0313.
