We're dividing 30521053 by 664 
Let's see how many times 664 fits into 30521053.

On to step 1:
If we divide 3 by 664, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 664

Step 2:
When dividing 30 by 664, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 664

Let's proceed to step 3:
If we divide 305 by 664, we get 0 and a remainder of 305.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 305 after subtracting 0 from 305.
Fetch the next digit (2) from the dividend, attach it to 305 and continue: 3052 / 664

Advancing to step 4:
664 goes into 3052 4 times with a remainder of 396.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 2656 away from 3052, we end up with 396.
Grab the next digit (1) from the dividend, add it to 396, then carry on: 3961 / 664

Going ahead to step 5:
664 goes into 3961 5 times with a remainder of 641.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtracting 3320 from 3961 leaves us with 641.
Append the next digit (0) from the dividend to 641 and continue with: 6410 / 664

Let's proceed to step 6:
The number 664 fits into 6410 9 times, leaving a remainder of 434.
Record the quotient 9 as the next digit in the result. 
Result so far: 459.0
Subtracting 5976 from 6410 leaves us with 434.
Fetch the next digit (5) from the dividend, attach it to 434 and continue: 4345 / 664

Let's proceed to step 7:
4345 divided by 664 is 6 with a remainder of 361.
Use 6 as the next digit of our solution. 
Result so far: 4596.0
Subtracting 3984 from 4345 leaves us with 361.
Grab the next digit (3) from the dividend, add it to 361, then carry on: 3613 / 664

Moving on to step 8:
The number 664 fits into 3613 5 times, leaving a remainder of 293.
Write down 5 as next digit of the result. 
Result so far: 45965.0
Subtracting 3320 from 3613 leaves us with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Let's proceed to step 9:
2930 divided by 664 is 4 with a remainder of 274.
Record the quotient 4 as the next digit in the result. 
Result so far: 45965.4
The remainder is 274 after subtracting 2656 from 2930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 10:
When dividing 2740 by 664, we get 4 with a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 45965.44
Subtracting 2656 from 2740 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Our division results in 45965.44 with a remaining 0.084.
