39586426 divided by 486 
We want to divide 39586426 by 486.

Let's proceed to step 1:
3 divided by 486 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 486

Step 2:
If we divide 39 by 486, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 486

Advancing to step 3:
395 divided by 486 is 0 with a remainder of 395.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 395 to get 395.
Grab the next digit (8) from the dividend, add it to 395, then carry on: 3958 / 486

On to step 4:
When dividing 3958 by 486, we get 8 with a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 3888 from 3958 and we're left with 70.
Include the next digit (6) from the dividend after 70, then repeat: 706 / 486

Let's proceed to step 5:
486 goes into 706 1 times with a remainder of 220.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
The remainder is 220 after subtracting 486 from 706.
Take the next digit (4) from the dividend and append it to 220, then repeat: 2204 / 486

Advancing to step 6:
2204 divided by 486 is 4 with a remainder of 260.
Write down 4 as next digit of the result. 
Result so far: 814.0
Subtracting 1944 from 2204 leaves us with 260.
Include the next digit (2) from the dividend after 260, then repeat: 2602 / 486

Let's proceed to step 7:
2602 divided by 486 is 5 with a remainder of 172.
Use 5 as the next digit of our solution. 
Result so far: 8145.0
Deduct 2430 from 2602 and we're left with 172.
Fetch the next digit (6) from the dividend, attach it to 172 and continue: 1726 / 486

On to step 8:
The number 486 fits into 1726 3 times, leaving a remainder of 268.
The next digit of our result is 3. 
Result so far: 81453.0
If we take 1458 away from 1726, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 9:
486 can be fit into 2680 5 times, resulting in a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 81453.5
Subtracting 2430 from 2680 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 10:
When dividing 2500 by 486, we get 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 81453.55
Subtracting 2430 from 2500 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 81453.55 and a remainder of 0.07.
