We're dividing 142424 by 51 
We're looking to find how many times 51 goes into 142424.

On to step 1:
51 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 51

Moving on to step 2:
14 divided by 51 is 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 51

Advancing to step 3:
If we divide 142 by 51, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 40 after subtracting 102 from 142.
Bring next digit (4) of the dividend behind the 40 and repeat the process: 404 / 51

Going ahead to step 4:
When dividing 404 by 51, we get 7 with a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we take 357 away from 404, we end up with 47.
Append the next digit (2) from the dividend to 47 and continue with: 472 / 51

Let's proceed to step 5:
51 can be fit into 472 9 times, resulting in a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 279.0
If we subtract 459 from 472, we get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 51

Going ahead to step 6:
134 divided by 51 is 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 2792.0
The remainder is 32 after subtracting 102 from 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
If we divide 320 by 51, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 2792.6
Deduct 306 from 320 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
When dividing 140 by 51, we get 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 2792.62
If we subtract 102 from 140, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
When dividing 380 by 51, we get 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 2792.627
If we subtract 357 from 380, we 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.

Advancing to step 10:
230 divided by 51 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 2792.6274
Subtracting 204 from 230 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
260 divided by 51 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 2792.62745
Deduct 255 from 260 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
51 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 2792.62745
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
When dividing 500 by 51, we get 9 with a remainder of 41.
The next digit of our result is 9. 
Result so far: 2792.6274509
Deduct 459 from 500 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 14:
If we divide 410 by 51, we get 8 and a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 2792.62745098
Subtracting 408 from 410 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 2792.62745098 with a remaining 2e-09.
