Let's divide 186978 by 45
We're looking to find how many times 45 goes into 186978.

Step 1:
45 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 45

Going ahead to step 2:
When dividing 18 by 45, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 45

On to step 3:
The number 45 fits into 186 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 180 from 186, we get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 45

Let's proceed to step 4:
69 divided by 45 is 1 with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
The remainder is 24 after subtracting 45 from 69.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 45

Step 5:
When dividing 247 by 45, we get 5 with a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 415.0
The remainder is 22 after subtracting 225 from 247.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 45

Let's proceed to step 6:
If we divide 228 by 45, we get 5 and a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 4155.0
The remainder is 3 after subtracting 225 from 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
If we divide 30 by 45, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 4155.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 4155.06
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 4155.066
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 4155.066 with a remaining 0.003.
