We're dividing 51404640 by 187 
Our goal is to divide 51404640 by 187.

Going ahead to step 1:
When dividing 5 by 187, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 187

Step 2:
187 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 187

On to step 3:
187 can be fit into 514 2 times, resulting in a remainder of 140.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 374 from 514, we get 140.
Bring next digit (0) of the dividend behind the 140 and repeat the process: 1400 / 187

Moving on to step 4:
When dividing 1400 by 187, we get 7 with a remainder of 91.
Write down 7 as next digit of the result. 
Result so far: 27.0
The remainder is 91 after subtracting 1309 from 1400.
Take the next digit (4) from the dividend and append it to 91, then repeat: 914 / 187

Step 5:
The number 187 fits into 914 4 times, leaving a remainder of 166.
Put 4 as the next digit of the answer. 
Result so far: 274.0
If we subtract 748 from 914, we get 166.
Include the next digit (6) from the dividend after 166, then repeat: 1666 / 187

On to step 6:
187 can be fit into 1666 8 times, resulting in a remainder of 170.
The number 8 becomes the next digit in our result. 
Result so far: 2748.0
Subtract 1496 from 1666 to get 170.
Append the next digit (4) from the dividend to 170 and continue with: 1704 / 187

Going ahead to step 7:
If we divide 1704 by 187, we get 9 and a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 27489.0
Subtracting 1683 from 1704 leaves us with 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 187

On to step 8:
210 divided by 187 is 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 274891.0
Subtract 187 from 210 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
If we divide 230 by 187, we get 1 and a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 274891.1
Subtract 187 from 230 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 10:
430 divided by 187 is 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 274891.12
Subtracting 374 from 430 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
When dividing 560 by 187, we get 2 with a remainder of 186.
The next digit of our result is 2. 
Result so far: 274891.122
Deduct 374 from 560 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Our division results in 274891.122 with a remaining 0.0186.
