Let's divide 142508 by 51
We want to figure out the number of times 142508 can be divided by 51.

On to step 1:
51 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 51

Going ahead to step 2:
51 goes into 14 0 times with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 51

Advancing to step 3:
51 can be fit into 142 2 times, resulting in a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 102 from 142, we get 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 51

On to step 4:
If we divide 405 by 51, we get 7 and a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we subtract 357 from 405, we get 48.
Include the next digit (0) from the dividend after 48, then repeat: 480 / 51

Moving on to step 5:
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: 279.0
If we take 459 away from 480, we end up with 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 51

Moving on to step 6:
The number 51 fits into 218 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 2794.0
Deduct 204 from 218 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 7:
51 can be fit into 140 2 times, resulting in a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 2794.2
Subtract 102 from 140 to 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.

Advancing to step 8:
When dividing 380 by 51, we get 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 2794.27
Deduct 357 from 380 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
When dividing 230 by 51, we get 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 2794.274
If we subtract 204 from 230, we get 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 10:
When dividing 260 by 51, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 2794.2745
Subtract 255 from 260 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
51 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 2794.2745
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
51 can be fit into 500 9 times, resulting in a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 2794.274509
If we take 459 away from 500, we end up 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.

Step 13:
51 can be fit into 410 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 2794.2745098
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.

Step 14:
51 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 2794.2745098
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 2794.2745098 with a balance of 2e-08.
