We're dividing 803668 by 51 
We want to divide 803668 by 51.

Moving on to step 1:
The number 51 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 51

Advancing to step 2:
51 goes into 80 1 times with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 51 from 80 to get 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 51

Let's proceed to step 3:
51 goes into 293 5 times with a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 255 from 293 leaves us with 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 51

Moving on to step 4:
386 divided by 51 is 7 with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
Subtract 357 from 386 to get 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 51

Step 5:
If we divide 296 by 51, we get 5 and a remainder of 41.
Record the quotient 5 as the next digit in the result. 
Result so far: 1575.0
The remainder is 41 after subtracting 255 from 296.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 51

Going ahead to step 6:
51 goes into 418 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 15758.0
The remainder is 10 after subtracting 408 from 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
51 goes into 100 1 times with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 15758.1
If we take 51 away from 100, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 8:
51 can be fit into 490 9 times, resulting in a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 15758.19
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
The number 51 fits into 310 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 15758.196
The remainder is 4 after subtracting 306 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
51 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 15758.196
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
When dividing 400 by 51, we get 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 15758.19607
Subtracting 357 from 400 leaves us 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.

On to step 12:
The number 51 fits into 430 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 15758.196078
Subtracting 408 from 430 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
220 divided by 51 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 15758.1960784
Deduct 204 from 220 and we're left 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.

On to step 14:
The number 51 fits into 160 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 15758.19607843
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.

The final outcome is 15758.19607843, with a leftover of 7e-09.
