We look at the division of 55487357 by 369 
Let's see how many times 369 fits into 55487357.

Advancing to step 1:
369 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 369

Let's proceed to step 2:
369 can be fit into 55 0 times, resulting in a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 369

Let's proceed to step 3:
If we divide 554 by 369, we get 1 and a remainder of 185.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 369 from 554, we get 185.
Grab the next digit (8) from the dividend, add it to 185, then carry on: 1858 / 369

Step 4:
When dividing 1858 by 369, we get 5 with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 1845 from 1858 to get 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 369

Step 5:
137 divided by 369 is 0 with a remainder of 137.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Subtract 0 from 137 to get 137.
Append the next digit (3) from the dividend to 137 and continue with: 1373 / 369

Moving on to step 6:
369 can be fit into 1373 3 times, resulting in a remainder of 266.
Record the quotient 3 as the next digit in the result. 
Result so far: 1503.0
Deduct 1107 from 1373 and we're left with 266.
Grab the next digit (5) from the dividend, add it to 266, then carry on: 2665 / 369

Going ahead to step 7:
369 goes into 2665 7 times with a remainder of 82.
Put 7 as the next digit of the answer. 
Result so far: 15037.0
The remainder is 82 after subtracting 2583 from 2665.
Include the next digit (7) from the dividend after 82, then repeat: 827 / 369

Going ahead to step 8:
369 can be fit into 827 2 times, resulting in a remainder of 89.
The number 2 becomes the next digit in our result. 
Result so far: 150372.0
Subtract 738 from 827 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 9:
The number 369 fits into 890 2 times, leaving a remainder of 152.
Put 2 as the next digit of the answer. 
Result so far: 150372.2
Subtracting 738 from 890 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 10:
369 goes into 1520 4 times with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 150372.24
Subtracting 1476 from 1520 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
369 goes into 440 1 times with a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 150372.241
If we subtract 369 from 440, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 12:
369 can be fit into 710 1 times, resulting in a remainder of 341.
The number 1 becomes the next digit in our result. 
Result so far: 150372.2411
Deduct 369 from 710 and we're left with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

The final outcome is 150372.2411, with a leftover of 0.00341.
