Let's divide 54861440 by 366
We want to figure out the number of times 54861440 can be divided by 366.

Step 1:
366 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 366

Step 2:
If we divide 54 by 366, we get 0 and a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Include the next digit (8) from the dividend after 54, then repeat: 548 / 366

Let's proceed to step 3:
366 can be fit into 548 1 times, resulting in a remainder of 182.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 366 from 548 and we're left with 182.
Grab the next digit (6) from the dividend, add it to 182, then carry on: 1826 / 366

On to step 4:
366 can be fit into 1826 4 times, resulting in a remainder of 362.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 1464 from 1826 leaves us with 362.
Bring next digit (1) of the dividend behind the 362 and repeat the process: 3621 / 366

Going ahead to step 5:
366 goes into 3621 9 times with a remainder of 327.
Write down 9 as next digit of the result. 
Result so far: 149.0
Deduct 3294 from 3621 and we're left with 327.
Grab the next digit (4) from the dividend, add it to 327, then carry on: 3274 / 366

Advancing to step 6:
If we divide 3274 by 366, we get 8 and a remainder of 346.
Record the quotient 8 as the next digit in the result. 
Result so far: 1498.0
Subtract 2928 from 3274 to get 346.
Bring next digit (4) of the dividend behind the 346 and repeat the process: 3464 / 366

Moving on to step 7:
366 can be fit into 3464 9 times, resulting in a remainder of 170.
Use 9 as the next digit of our solution. 
Result so far: 14989.0
If we subtract 3294 from 3464, we get 170.
Append the next digit (0) from the dividend to 170 and continue with: 1700 / 366

Step 8:
366 can be fit into 1700 4 times, resulting in a remainder of 236.
Write down 4 as next digit of the result. 
Result so far: 149894.0
Subtract 1464 from 1700 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 9:
If we divide 2360 by 366, we get 6 and a remainder of 164.
The number 6 becomes the next digit in our result. 
Result so far: 149894.6
Subtract 2196 from 2360 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 10:
366 can be fit into 1640 4 times, resulting in a remainder of 176.
The next digit of our result is 4. 
Result so far: 149894.64
Deduct 1464 from 1640 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 11:
If we divide 1760 by 366, we get 4 and a remainder of 296.
The next digit of our result is 4. 
Result so far: 149894.644
If we subtract 1464 from 1760, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final result is 149894.644 with a remainder of 0.0296.
