We're dividing 810887 by 39 
Let's see how many times 39 fits into 810887.

On to step 1:
If we divide 8 by 39, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 39

Advancing to step 2:
39 can be fit into 81 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 78 from 81 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 39

Going ahead to step 3:
The number 39 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 30 leaves us with 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 39

Advancing to step 4:
308 divided by 39 is 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 207.0
Subtracting 273 from 308 leaves us with 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 39

Let's proceed to step 5:
39 goes into 358 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 2079.0
Subtract 351 from 358 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 39

Let's proceed to step 6:
If we divide 77 by 39, we get 1 and a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 20791.0
The remainder is 38 after subtracting 39 from 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
The number 39 fits into 380 9 times, leaving a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 20791.9
Subtracting 351 from 380 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 8:
290 divided by 39 is 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 20791.97
The remainder is 17 after subtracting 273 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
If we divide 170 by 39, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 20791.974
If we subtract 156 from 170, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
If we divide 140 by 39, we get 3 and a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 20791.9743
If we take 117 away from 140, 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.

Let's proceed to step 11:
230 divided by 39 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 20791.97435
Subtract 195 from 230 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 12:
The number 39 fits into 350 8 times, leaving a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 20791.974358
Deduct 312 from 350 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
380 divided by 39 is 9 with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 20791.9743589
Deduct 351 from 380 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 14:
39 goes into 290 7 times with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 20791.97435897
Subtract 273 from 290 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The quotient of the division is 20791.97435897, and the remainder is 1.7e-08.
