959581 divided by 51 
Our goal is to divide 959581 by 51.

Let's proceed to step 1:
51 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 51

On to step 2:
51 can be fit into 95 1 times, resulting in a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 51 from 95 to get 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 51

Advancing to step 3:
449 divided by 51 is 8 with a remainder of 41.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 41 after subtracting 408 from 449.
Grab the next digit (5) from the dividend, add it to 41, then carry on: 415 / 51

On to step 4:
415 divided by 51 is 8 with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 188.0
Subtract 408 from 415 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 51

Going ahead to step 5:
78 divided by 51 is 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1881.0
Subtract 51 from 78 to get 27.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 51

Step 6:
51 goes into 271 5 times with a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 18815.0
Subtract 255 from 271 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
51 goes into 160 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 18815.3
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
51 goes into 70 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 18815.31
Subtract 51 from 70 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
When dividing 190 by 51, we get 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 18815.313
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.

On to step 10:
The number 51 fits into 370 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 18815.3137
Subtracting 357 from 370 leaves us 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.

On to step 11:
51 goes into 130 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 18815.31372
Subtracting 102 from 130 leaves us with 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 12:
51 can be fit into 280 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 18815.313725
If we subtract 255 from 280, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
51 can be fit into 250 4 times, resulting in a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 18815.3137254
Deduct 204 from 250 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 14:
51 goes into 460 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 18815.31372549
If we subtract 459 from 460, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 18815.31372549, with a leftover of 1e-09.
