39752394 divided by 864 
We want to figure out the number of times 39752394 can be divided by 864.

On to step 1:
When dividing 3 by 864, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 864

On to step 2:
864 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 864

Step 3:
864 can be fit into 397 0 times, resulting in a remainder of 397.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 397, we get 397.
Take the next digit (5) from the dividend and append it to 397, then repeat: 3975 / 864

Moving on to step 4:
864 goes into 3975 4 times with a remainder of 519.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 3456 from 3975 leaves us with 519.
Fetch the next digit (2) from the dividend, attach it to 519 and continue: 5192 / 864

Let's proceed to step 5:
864 goes into 5192 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 46.0
The remainder is 8 after subtracting 5184 from 5192.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 864

Advancing to step 6:
The number 864 fits into 83 0 times, leaving a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 460.0
Subtracting 0 from 83 leaves us with 83.
Include the next digit (9) from the dividend after 83, then repeat: 839 / 864

Let's proceed to step 7:
If we divide 839 by 864, we get 0 and a remainder of 839.
The next digit of our result is 0. 
Result so far: 4600.0
If we subtract 0 from 839, we get 839.
Bring next digit (4) of the dividend behind the 839 and repeat the process: 8394 / 864

Going ahead to step 8:
The number 864 fits into 8394 9 times, leaving a remainder of 618.
Record the quotient 9 as the next digit in the result. 
Result so far: 46009.0
If we subtract 7776 from 8394, we get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Step 9:
When dividing 6180 by 864, we get 7 with a remainder of 132.
Write down 7 as next digit of the result. 
Result so far: 46009.7
If we take 6048 away from 6180, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 10:
If we divide 1320 by 864, we get 1 and a remainder of 456.
Put 1 as the next digit of the answer. 
Result so far: 46009.71
Deduct 864 from 1320 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Let's proceed to step 11:
864 can be fit into 4560 5 times, resulting in a remainder of 240.
The number 5 becomes the next digit in our result. 
Result so far: 46009.715
If we take 4320 away from 4560, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 12:
The number 864 fits into 2400 2 times, leaving a remainder of 672.
The next digit of our result is 2. 
Result so far: 46009.7152
If we take 1728 away from 2400, 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 13:
864 goes into 6720 7 times with a remainder of 672.
Put 7 as the next digit of the answer. 
Result so far: 46009.71527
Subtracting 6048 from 6720 leaves us 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.

Moving on to step 14:
864 can be fit into 6720 7 times, resulting in a remainder of 672.
Record the quotient 7 as the next digit in the result. 
Result so far: 46009.715277
If we subtract 6048 from 6720, we get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

After the division, we end up with 46009.715277 and a remainder of 6.72e-05.
