Let's divide 239473 by 51
We want to divide 239473 by 51.

On to step 1:
When dividing 2 by 51, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 51

Advancing 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
If we take 0 away from 23, we end up with 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 51

On to step 3:
When dividing 239 by 51, we get 4 with a remainder of 35.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 204 from 239 leaves us with 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 51

Moving on to step 4:
The number 51 fits into 354 6 times, leaving a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtracting 306 from 354 leaves us with 48.
Fetch the next digit (7) from the dividend, attach it to 48 and continue: 487 / 51

On to step 5:
If we divide 487 by 51, we get 9 and a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 469.0
Deduct 459 from 487 and we're left with 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 51

Step 6:
When dividing 283 by 51, we get 5 with a remainder of 28.
The next digit of our result is 5. 
Result so far: 4695.0
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.

Step 7:
51 goes into 280 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 4695.5
Deduct 255 from 280 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
The number 51 fits into 250 4 times, leaving a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 4695.54
Deduct 204 from 250 and we're left 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.

Moving on to step 9:
When dividing 460 by 51, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 4695.549
If we take 459 away from 460, we end up 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.

Advancing to step 10:
If we divide 10 by 51, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4695.549
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.

Advancing to step 11:
100 divided by 51 is 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 4695.54901
The remainder is 49 after subtracting 51 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 12:
When dividing 490 by 51, we get 9 with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 4695.549019
Subtracting 459 from 490 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 13:
51 can be fit into 310 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 4695.5490196
Subtract 306 from 310 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
51 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4695.5490196
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.

After the division, we end up with 4695.5490196 and a remainder of 4e-08.
