We divide 39861407 by 817
We want to divide 39861407 by 817.

Let's proceed to step 1:
The number 817 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 817

Moving on to step 2:
817 goes into 39 0 times with 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.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 817

On to step 3:
817 can be fit into 398 0 times, resulting in a remainder of 398.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 398, we get 398.
Grab the next digit (6) from the dividend, add it to 398, then carry on: 3986 / 817

Going ahead to step 4:
If we divide 3986 by 817, we get 4 and a remainder of 718.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 3268 away from 3986, we end up with 718.
Append the next digit (1) from the dividend to 718 and continue with: 7181 / 817

Moving on to step 5:
If we divide 7181 by 817, we get 8 and a remainder of 645.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtracting 6536 from 7181 leaves us with 645.
Grab the next digit (4) from the dividend, add it to 645, then carry on: 6454 / 817

Moving on to step 6:
817 can be fit into 6454 7 times, resulting in a remainder of 735.
The next digit of our result is 7. 
Result so far: 487.0
If we take 5719 away from 6454, we end up with 735.
Take the next digit (0) from the dividend and append it to 735, then repeat: 7350 / 817

Advancing to step 7:
If we divide 7350 by 817, we get 8 and a remainder of 814.
The next digit of our result is 8. 
Result so far: 4878.0
The remainder is 814 after subtracting 6536 from 7350.
Include the next digit (7) from the dividend after 814, then repeat: 8147 / 817

On to step 8:
8147 divided by 817 is 9 with a remainder of 794.
Put 9 as the next digit of the answer. 
Result so far: 48789.0
If we subtract 7353 from 8147, we get 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Step 9:
If we divide 7940 by 817, we get 9 and a remainder of 587.
Record the quotient 9 as the next digit in the result. 
Result so far: 48789.9
The remainder is 587 after subtracting 7353 from 7940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Let's proceed to step 10:
817 goes into 5870 7 times with a remainder of 151.
Put 7 as the next digit of the answer. 
Result so far: 48789.97
If we subtract 5719 from 5870, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Advancing to step 11:
817 can be fit into 1510 1 times, resulting in a remainder of 693.
The number 1 becomes the next digit in our result. 
Result so far: 48789.971
The remainder is 693 after subtracting 817 from 1510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

Going ahead to step 12:
817 can be fit into 6930 8 times, resulting in a remainder of 394.
Record the quotient 8 as the next digit in the result. 
Result so far: 48789.9718
The remainder is 394 after subtracting 6536 from 6930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 13:
The number 817 fits into 3940 4 times, leaving a remainder of 672.
Record the quotient 4 as the next digit in the result. 
Result so far: 48789.97184
If we take 3268 away from 3940, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Advancing to step 14:
The number 817 fits into 6720 8 times, leaving a remainder of 184.
Put 8 as the next digit of the answer. 
Result so far: 48789.971848
Deduct 6536 from 6720 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 15:
When dividing 1840 by 817, we get 2 with a remainder of 206.
Put 2 as the next digit of the answer. 
Result so far: 48789.9718482
Subtracting 1634 from 1840 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 16:
The number 817 fits into 2060 2 times, leaving a remainder of 426.
Put 2 as the next digit of the answer. 
Result so far: 48789.97184822
Subtract 1634 from 2060 to get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

After the division, we end up with 48789.97184822 and a remainder of 4.26e-07.
