We're dividing 30105664 by 450 
Our goal is to divide 30105664 by 450.

Advancing to step 1:
The number 450 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 450

Going ahead to step 2:
450 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 450

Let's proceed to step 3:
If we divide 301 by 450, we get 0 and a remainder of 301.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 301, we end up with 301.
Grab the next digit (0) from the dividend, add it to 301, then carry on: 3010 / 450

Step 4:
When dividing 3010 by 450, we get 6 with a remainder of 310.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 2700 away from 3010, we end up with 310.
Bring next digit (5) of the dividend behind the 310 and repeat the process: 3105 / 450

Let's proceed to step 5:
When dividing 3105 by 450, we get 6 with a remainder of 405.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
The remainder is 405 after subtracting 2700 from 3105.
Include the next digit (6) from the dividend after 405, then repeat: 4056 / 450

Let's proceed to step 6:
450 goes into 4056 9 times with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 669.0
If we take 4050 away from 4056, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 450

Step 7:
450 goes into 66 0 times with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 6690.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 450

Step 8:
450 can be fit into 664 1 times, resulting in a remainder of 214.
Write down 1 as next digit of the result. 
Result so far: 66901.0
The remainder is 214 after subtracting 450 from 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 9:
2140 divided by 450 is 4 with a remainder of 340.
Write down 4 as next digit of the result. 
Result so far: 66901.4
The remainder is 340 after subtracting 1800 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 10:
3400 divided by 450 is 7 with a remainder of 250.
Put 7 as the next digit of the answer. 
Result so far: 66901.47
Subtract 3150 from 3400 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 11:
450 goes into 2500 5 times with a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 66901.475
Subtract 2250 from 2500 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 12:
If we divide 2500 by 450, we get 5 and a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 66901.4755
The remainder is 250 after subtracting 2250 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final outcome is 66901.4755, with a leftover of 0.0025.
