30178325 ÷ 661 
We're looking to find how many times 661 goes into 30178325.

On to step 1:
661 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 661

Let's proceed to step 2:
30 divided by 661 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 661

Let's proceed to step 3:
661 can be fit into 301 0 times, resulting in a remainder of 301.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 301 leaves us with 301.
Grab the next digit (7) from the dividend, add it to 301, then carry on: 3017 / 661

Moving on to step 4:
661 goes into 3017 4 times with a remainder of 373.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 2644 from 3017 and we're left with 373.
Include the next digit (8) from the dividend after 373, then repeat: 3738 / 661

On to step 5:
3738 divided by 661 is 5 with a remainder of 433.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we take 3305 away from 3738, we end up with 433.
Bring next digit (3) of the dividend behind the 433 and repeat the process: 4333 / 661

Step 6:
When dividing 4333 by 661, we get 6 with a remainder of 367.
Use 6 as the next digit of our solution. 
Result so far: 456.0
Subtract 3966 from 4333 to get 367.
Include the next digit (2) from the dividend after 367, then repeat: 3672 / 661

On to step 7:
When dividing 3672 by 661, we get 5 with a remainder of 367.
Use 5 as the next digit of our solution. 
Result so far: 4565.0
Subtract 3305 from 3672 to get 367.
Include the next digit (5) from the dividend after 367, then repeat: 3675 / 661

Step 8:
When dividing 3675 by 661, we get 5 with a remainder of 370.
Write down 5 as next digit of the result. 
Result so far: 45655.0
The remainder is 370 after subtracting 3305 from 3675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 9:
3700 divided by 661 is 5 with a remainder of 395.
The number 5 becomes the next digit in our result. 
Result so far: 45655.5
If we subtract 3305 from 3700, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Moving on to step 10:
3950 divided by 661 is 5 with a remainder of 645.
Put 5 as the next digit of the answer. 
Result so far: 45655.55
If we subtract 3305 from 3950, we get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

The final result is 45655.55 with a remainder of 0.645.
