We're dividing 237861 by 51 
We want to divide 237861 by 51.

Step 1:
51 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 51

Going ahead to step 2:
When dividing 23 by 51, we get 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 51

Step 3:
237 divided by 51 is 4 with a remainder of 33.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 204 from 237 leaves us with 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 51

On to step 4:
338 divided by 51 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Subtracting 306 from 338 leaves us with 32.
Grab the next digit (6) from the dividend, add it to 32, then carry on: 326 / 51

Moving on to step 5:
When dividing 326 by 51, we get 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 466.0
If we subtract 306 from 326, we get 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 51

Advancing to step 6:
The number 51 fits into 201 3 times, leaving a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 4663.0
If we subtract 153 from 201, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 7:
480 divided by 51 is 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 4663.9
Subtract 459 from 480 to 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.

Step 8:
51 can be fit into 210 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 4663.94
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.

Moving on to step 9:
If we divide 60 by 51, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 4663.941
Subtracting 51 from 60 leaves us 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.

Advancing to step 10:
If we divide 90 by 51, we get 1 and a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 4663.9411
The remainder is 39 after subtracting 51 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final result is 4663.9411 with a remainder of 0.00039.
