729986 ÷ 51 
Our goal is to divide 729986 by 51.

Moving on to step 1:
The number 51 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 51

Advancing to step 2:
The number 51 fits into 72 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 51 from 72 to get 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 51

Advancing to step 3:
The number 51 fits into 219 4 times, leaving a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 204 from 219, we get 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 51

Going ahead to step 4:
51 goes into 159 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 143.0
Subtracting 153 from 159 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 51

On to step 5:
The number 51 fits into 68 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1431.0
Deduct 51 from 68 and we're left with 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 51

On to step 6:
If we divide 176 by 51, we get 3 and a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 14313.0
If we take 153 away from 176, we end up 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.

Moving on to step 7:
230 divided by 51 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 14313.4
If we take 204 away from 230, we end up 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.

Moving on to step 8:
51 can be fit into 260 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 14313.45
Subtracting 255 from 260 leaves us 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.

Step 9:
If we divide 50 by 51, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 14313.45
If we take 0 away from 50, we end up 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.

Step 10:
If we divide 500 by 51, we get 9 and a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 14313.4509
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.

Going ahead to step 11:
When dividing 410 by 51, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 14313.45098
If we take 408 away from 410, we end up 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.

On to step 12:
When dividing 20 by 51, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 14313.45098
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
When dividing 200 by 51, we get 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 14313.4509803
Subtracting 153 from 200 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 14:
The number 51 fits into 470 9 times, leaving a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 14313.45098039
Subtract 459 from 470 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 14313.45098039 and a remainder of 1.1e-08.
