789665 divided by 51 
Our goal is to divide 789665 by 51.

Advancing to step 1:
When dividing 7 by 51, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 51

Moving on to step 2:
When dividing 78 by 51, we get 1 with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 51 from 78, we get 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 51

On to step 3:
When dividing 279 by 51, we get 5 with a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 24 after subtracting 255 from 279.
Fetch the next digit (6) from the dividend, attach it to 24 and continue: 246 / 51

On to step 4:
246 divided by 51 is 4 with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 154.0
Subtract 204 from 246 to get 42.
Grab the next digit (6) from the dividend, add it to 42, then carry on: 426 / 51

Step 5:
51 can be fit into 426 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 1548.0
The remainder is 18 after subtracting 408 from 426.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 51

Going ahead to step 6:
185 divided by 51 is 3 with a remainder of 32.
The number 3 becomes the next digit in our result. 
Result so far: 15483.0
If we subtract 153 from 185, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
The number 51 fits into 320 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 15483.6
The remainder is 14 after subtracting 306 from 320.
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:
If we divide 140 by 51, we get 2 and a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 15483.62
The remainder is 38 after subtracting 102 from 140.
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:
If we divide 380 by 51, we get 7 and a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 15483.627
Subtract 357 from 380 to 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.

Moving on to step 10:
If we divide 230 by 51, we get 4 and a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 15483.6274
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.

Moving on 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: 15483.62745
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.

Advancing to step 12:
The number 51 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 15483.62745
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.

Moving on to step 13:
51 can be fit into 500 9 times, resulting in a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 15483.6274509
The remainder is 41 after subtracting 459 from 500.
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 14:
When dividing 410 by 51, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 15483.62745098
The remainder is 2 after subtracting 408 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 15483.62745098 with a remainder of 2e-09.
