Let's divide 201223 by 51
Let's see how many times 51 fits into 201223.

Let's proceed to step 1:
2 divided by 51 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 51

Moving on to step 2:
The number 51 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 51

Advancing to step 3:
The number 51 fits into 201 3 times, leaving a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 48 after subtracting 153 from 201.
Append the next digit (2) from the dividend to 48 and continue with: 482 / 51

Going ahead to step 4:
When dividing 482 by 51, we get 9 with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 39.0
The remainder is 23 after subtracting 459 from 482.
Grab the next digit (2) from the dividend, add it to 23, then carry on: 232 / 51

Advancing to step 5:
If we divide 232 by 51, we get 4 and a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 394.0
Subtracting 204 from 232 leaves us with 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 51

Step 6:
The number 51 fits into 283 5 times, leaving a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 3945.0
Deduct 255 from 283 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
If we divide 280 by 51, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 3945.5
The remainder is 25 after subtracting 255 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
51 can be fit into 250 4 times, resulting in a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 3945.54
Subtracting 204 from 250 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
51 goes into 460 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 3945.549
Deduct 459 from 460 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
If we divide 10 by 51, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 3945.549
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
51 can be fit into 100 1 times, resulting in a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 3945.54901
If we subtract 51 from 100, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 12:
When dividing 490 by 51, we get 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 3945.549019
Subtract 459 from 490 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 13:
51 goes into 310 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 3945.5490196
If we take 306 away from 310, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
When dividing 40 by 51, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3945.5490196
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 3945.5490196 with a remaining 4e-08.
