200187 ÷ 51 
Let's see how many times 51 fits into 200187.

Going ahead to step 1:
When dividing 2 by 51, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 51

Let's proceed to step 2:
20 divided by 51 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 51

Step 3:
51 can be fit into 200 3 times, resulting in a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 47 after subtracting 153 from 200.
Append the next digit (1) from the dividend to 47 and continue with: 471 / 51

Let's proceed to step 4:
51 goes into 471 9 times with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtracting 459 from 471 leaves us with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 51

On to step 5:
The number 51 fits into 128 2 times, leaving a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 392.0
Subtract 102 from 128 to get 26.
Fetch the next digit (7) from the dividend, attach it to 26 and continue: 267 / 51

Going ahead to step 6:
If we divide 267 by 51, we get 5 and a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 3925.0
If we subtract 255 from 267, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
51 goes into 120 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 3925.2
The remainder is 18 after subtracting 102 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
51 can be fit into 180 3 times, resulting in a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 3925.23
Deduct 153 from 180 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
The number 51 fits into 270 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3925.235
Subtract 255 from 270 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
If we divide 150 by 51, we get 2 and a remainder of 48.
The next digit of our result is 2. 
Result so far: 3925.2352
Subtracting 102 from 150 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
When dividing 480 by 51, we get 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 3925.23529
If we subtract 459 from 480, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
51 can be fit into 210 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 3925.235294
Deduct 204 from 210 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
51 can be fit into 60 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 3925.2352941
If we take 51 away from 60, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
The number 51 fits into 90 1 times, leaving a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 3925.23529411
Subtract 51 from 90 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 3925.23529411 and a remainder of 3.9e-08.
