We look at the division of 30990064 by 483 
We're looking to find how many times 483 goes into 30990064.

Step 1:
483 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 483

On to step 2:
When dividing 30 by 483, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 483

Let's proceed to step 3:
If we divide 309 by 483, we get 0 and a remainder of 309.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 309 after subtracting 0 from 309.
Include the next digit (9) from the dividend after 309, then repeat: 3099 / 483

Moving on to step 4:
483 goes into 3099 6 times with a remainder of 201.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 201 after subtracting 2898 from 3099.
Bring next digit (0) of the dividend behind the 201 and repeat the process: 2010 / 483

On to step 5:
483 can be fit into 2010 4 times, resulting in a remainder of 78.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtracting 1932 from 2010 leaves us with 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 483

Going ahead to step 6:
If we divide 780 by 483, we get 1 and a remainder of 297.
The next digit of our result is 1. 
Result so far: 641.0
If we subtract 483 from 780, we get 297.
Grab the next digit (6) from the dividend, add it to 297, then carry on: 2976 / 483

On to step 7:
When dividing 2976 by 483, we get 6 with a remainder of 78.
The number 6 becomes the next digit in our result. 
Result so far: 6416.0
Deduct 2898 from 2976 and we're left with 78.
Append the next digit (4) from the dividend to 78 and continue with: 784 / 483

On to step 8:
784 divided by 483 is 1 with a remainder of 301.
Put 1 as the next digit of the answer. 
Result so far: 64161.0
If we subtract 483 from 784, we get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Moving on to step 9:
483 goes into 3010 6 times with a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 64161.6
If we subtract 2898 from 3010, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 10:
483 goes into 1120 2 times with a remainder of 154.
The next digit of our result is 2. 
Result so far: 64161.62
Subtracting 966 from 1120 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 11:
483 goes into 1540 3 times with a remainder of 91.
Record the quotient 3 as the next digit in the result. 
Result so far: 64161.623
If we take 1449 away from 1540, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 12:
483 goes into 910 1 times with a remainder of 427.
Put 1 as the next digit of the answer. 
Result so far: 64161.6231
If we subtract 483 from 910, we get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

On to step 13:
If we divide 4270 by 483, we get 8 and a remainder of 406.
Use 8 as the next digit of our solution. 
Result so far: 64161.62318
Subtracting 3864 from 4270 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Advancing to step 14:
If we divide 4060 by 483, we get 8 and a remainder of 196.
Record the quotient 8 as the next digit in the result. 
Result so far: 64161.623188
If we take 3864 away from 4060, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The final result is 64161.623188 with a remainder of 1.96e-05.
