Let's divide 143659 by 51
Our goal is to divide 143659 by 51.

Let's proceed to step 1:
The number 51 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 51

Advancing to step 2:
51 goes into 14 0 times with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 51

On to step 3:
The number 51 fits into 143 2 times, leaving a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 102 away from 143, we end up with 41.
Bring next digit (6) of the dividend behind the 41 and repeat the process: 416 / 51

Going ahead to step 4:
416 divided by 51 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 408 from 416 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 51

Going ahead to step 5:
51 can be fit into 85 1 times, resulting in a remainder of 34.
The next digit of our result is 1. 
Result so far: 281.0
Subtract 51 from 85 to get 34.
Include the next digit (9) from the dividend after 34, then repeat: 349 / 51

On to step 6:
51 goes into 349 6 times with a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 2816.0
Deduct 306 from 349 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
51 can be fit into 430 8 times, resulting in a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 2816.8
The remainder is 22 after subtracting 408 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
51 can be fit into 220 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 2816.84
If we take 204 away from 220, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
If we divide 160 by 51, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 2816.843
If we subtract 153 from 160, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
70 divided by 51 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 2816.8431
The remainder is 19 after subtracting 51 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 11:
The number 51 fits into 190 3 times, leaving a remainder of 37.
The next digit of our result is 3. 
Result so far: 2816.84313
If we subtract 153 from 190, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 12:
51 goes into 370 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 2816.843137
If we take 357 away from 370, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 13:
If we divide 130 by 51, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 2816.8431372
Subtract 102 from 130 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
51 can be fit into 280 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 2816.84313725
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.

In conclusion, the division gives 2816.84313725 with a balance of 2.5e-08.
