We're dividing 807902 by 39 
We're looking to find how many times 39 goes into 807902.

On to step 1:
39 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 39

Advancing to step 2:
39 can be fit into 80 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 78 from 80 leaves us with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 39

Moving on to step 3:
27 divided by 39 is 0 with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 27 to get 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 39

Step 4:
39 can be fit into 279 7 times, resulting in a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 207.0
The remainder is 6 after subtracting 273 from 279.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 39

Going ahead to step 5:
60 divided by 39 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 2071.0
If we subtract 39 from 60, we get 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 39

Going ahead to step 6:
If we divide 212 by 39, we get 5 and a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 20715.0
Subtract 195 from 212 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.

Going ahead to step 7:
If we divide 170 by 39, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 20715.4
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.

Advancing to step 8:
When dividing 140 by 39, we get 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 20715.43
Subtract 117 from 140 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.

Going ahead to step 9:
If we divide 230 by 39, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 20715.435
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.

Going ahead to step 10:
When dividing 350 by 39, we get 8 with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 20715.4358
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 11:
The number 39 fits into 380 9 times, leaving a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 20715.43589
If we subtract 351 from 380, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 12:
If we divide 290 by 39, we get 7 and a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 20715.435897
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.

Step 13:
39 goes into 170 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 20715.4358974
Subtracting 156 from 170 leaves us with 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 14:
When dividing 140 by 39, we get 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 20715.43589743
If we subtract 117 from 140, we 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.

The final result is 20715.43589743 with a remainder of 2.3e-08.
