We're dividing 782586 by 51 
We're looking to find how many times 51 goes into 782586.

Step 1:
When dividing 7 by 51, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 51

Going ahead 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
Subtracting 51 from 78 leaves us with 27.
Fetch the next digit (2) from the dividend, attach it to 27 and continue: 272 / 51

Let's proceed to step 3:
The number 51 fits into 272 5 times, leaving a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 255 from 272, we get 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 51

Advancing to step 4:
The number 51 fits into 175 3 times, leaving a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 153.0
The remainder is 22 after subtracting 153 from 175.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 51

Step 5:
The number 51 fits into 228 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 1534.0
If we subtract 204 from 228, we get 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 51

Advancing to step 6:
51 goes into 246 4 times with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 15344.0
The remainder is 42 after subtracting 204 from 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 7:
51 goes into 420 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 15344.8
The remainder is 12 after subtracting 408 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
The number 51 fits into 120 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 15344.82
Subtracting 102 from 120 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
51 can be fit into 180 3 times, resulting in a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 15344.823
Subtracting 153 from 180 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 10:
If we divide 270 by 51, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 15344.8235
If we take 255 away from 270, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
The number 51 fits into 150 2 times, leaving a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 15344.82352
Subtracting 102 from 150 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
If we divide 480 by 51, we get 9 and a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 15344.823529
If we take 459 away from 480, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 13:
The number 51 fits into 210 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 15344.8235294
Deduct 204 from 210 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
The number 51 fits into 60 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 15344.82352941
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 15344.82352941 with a remainder of 9e-09.
