We divide 686087 by 39
We want to divide 686087 by 39.

Let's proceed to step 1:
6 divided by 39 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 39

Advancing to step 2:
If we divide 68 by 39, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 39 from 68 leaves us with 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 39

Moving on to step 3:
296 divided by 39 is 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 273 away from 296, we end up with 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 39

Let's proceed to step 4:
If we divide 230 by 39, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 175.0
Deduct 195 from 230 and we're left with 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 39

Moving on to step 5:
39 can be fit into 358 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 1759.0
Deduct 351 from 358 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 39

Step 6:
If we divide 77 by 39, we get 1 and a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 17591.0
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: 17591.9
The remainder is 29 after subtracting 351 from 380.
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 8:
If we divide 290 by 39, we get 7 and a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 17591.97
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.

Let's proceed to step 9:
The number 39 fits into 170 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 17591.974
If we take 156 away from 170, we end up 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 10:
When dividing 140 by 39, we get 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 17591.9743
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.

Advancing to step 11:
If we divide 230 by 39, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 17591.97435
If we subtract 195 from 230, we 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.

Moving on to step 12:
The number 39 fits into 350 8 times, leaving a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 17591.974358
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.

On 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: 17591.9743589
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.

Step 14:
290 divided by 39 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 17591.97435897
Deduct 273 from 290 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 17591.97435897 with a remaining 1.7e-08.
