19855428 divided by 366 
Our goal is to divide 19855428 by 366.

Step 1:
When dividing 1 by 366, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 366

Step 2:
366 can be fit into 19 0 times, resulting in a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 366

Let's proceed to step 3:
366 can be fit into 198 0 times, resulting in a remainder of 198.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 198 to get 198.
Append the next digit (5) from the dividend to 198 and continue with: 1985 / 366

Let's proceed to step 4:
When dividing 1985 by 366, we get 5 with a remainder of 155.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 1830 from 1985 to get 155.
Fetch the next digit (5) from the dividend, attach it to 155 and continue: 1555 / 366

Going ahead to step 5:
366 goes into 1555 4 times with a remainder of 91.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Deduct 1464 from 1555 and we're left with 91.
Grab the next digit (4) from the dividend, add it to 91, then carry on: 914 / 366

Advancing to step 6:
914 divided by 366 is 2 with a remainder of 182.
Use 2 as the next digit of our solution. 
Result so far: 542.0
If we subtract 732 from 914, we get 182.
Take the next digit (2) from the dividend and append it to 182, then repeat: 1822 / 366

Step 7:
366 goes into 1822 4 times with a remainder of 358.
Put 4 as the next digit of the answer. 
Result so far: 5424.0
If we subtract 1464 from 1822, we get 358.
Bring next digit (8) of the dividend behind the 358 and repeat the process: 3588 / 366

Advancing to step 8:
366 goes into 3588 9 times with a remainder of 294.
Write down 9 as next digit of the result. 
Result so far: 54249.0
Subtract 3294 from 3588 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 9:
The number 366 fits into 2940 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 54249.8
Deduct 2928 from 2940 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
120 divided by 366 is 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 54249.8
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
1200 divided by 366 is 3 with a remainder of 102.
The number 3 becomes the next digit in our result. 
Result so far: 54249.803
If we take 1098 away from 1200, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 12:
The number 366 fits into 1020 2 times, leaving a remainder of 288.
Write down 2 as next digit of the result. 
Result so far: 54249.8032
Subtracting 732 from 1020 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 13:
When dividing 2880 by 366, we get 7 with a remainder of 318.
Put 7 as the next digit of the answer. 
Result so far: 54249.80327
Deduct 2562 from 2880 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 14:
If we divide 3180 by 366, we get 8 and a remainder of 252.
The next digit of our result is 8. 
Result so far: 54249.803278
Subtracting 2928 from 3180 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 15:
2520 divided by 366 is 6 with a remainder of 324.
The number 6 becomes the next digit in our result. 
Result so far: 54249.8032786
The remainder is 324 after subtracting 2196 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 16:
The number 366 fits into 3240 8 times, leaving a remainder of 312.
The number 8 becomes the next digit in our result. 
Result so far: 54249.80327868
Subtract 2928 from 3240 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The final outcome is 54249.80327868, with a leftover of 3.12e-07.
