We're dividing 36419237 by 864 
We want to divide 36419237 by 864.

On to step 1:
864 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 864

Advancing to step 2:
When dividing 36 by 864, we get 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 864

Going ahead to step 3:
864 can be fit into 364 0 times, resulting in a remainder of 364.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 364, we get 364.
Fetch the next digit (1) from the dividend, attach it to 364 and continue: 3641 / 864

Let's proceed to step 4:
3641 divided by 864 is 4 with a remainder of 185.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 3456 away from 3641, we end up with 185.
Fetch the next digit (9) from the dividend, attach it to 185 and continue: 1859 / 864

Step 5:
1859 divided by 864 is 2 with a remainder of 131.
Write down 2 as next digit of the result. 
Result so far: 42.0
The remainder is 131 after subtracting 1728 from 1859.
Append the next digit (2) from the dividend to 131 and continue with: 1312 / 864

Step 6:
1312 divided by 864 is 1 with a remainder of 448.
Put 1 as the next digit of the answer. 
Result so far: 421.0
Subtract 864 from 1312 to get 448.
Bring next digit (3) of the dividend behind the 448 and repeat the process: 4483 / 864

Step 7:
When dividing 4483 by 864, we get 5 with a remainder of 163.
Use 5 as the next digit of our solution. 
Result so far: 4215.0
Subtracting 4320 from 4483 leaves us with 163.
Include the next digit (7) from the dividend after 163, then repeat: 1637 / 864

Let's proceed to step 8:
864 can be fit into 1637 1 times, resulting in a remainder of 773.
Record the quotient 1 as the next digit in the result. 
Result so far: 42151.0
Subtracting 864 from 1637 leaves us with 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

Going ahead to step 9:
864 goes into 7730 8 times with a remainder of 818.
The number 8 becomes the next digit in our result. 
Result so far: 42151.8
Subtracting 6912 from 7730 leaves us with 818.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8180, and continue the process.

Let's proceed to step 10:
When dividing 8180 by 864, we get 9 with a remainder of 404.
Record the quotient 9 as the next digit in the result. 
Result so far: 42151.89
The remainder is 404 after subtracting 7776 from 8180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 11:
4040 divided by 864 is 4 with a remainder of 584.
Record the quotient 4 as the next digit in the result. 
Result so far: 42151.894
If we subtract 3456 from 4040, we get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Going ahead to step 12:
If we divide 5840 by 864, we get 6 and a remainder of 656.
The number 6 becomes the next digit in our result. 
Result so far: 42151.8946
The remainder is 656 after subtracting 5184 from 5840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Advancing to step 13:
864 goes into 6560 7 times with a remainder of 512.
Record the quotient 7 as the next digit in the result. 
Result so far: 42151.89467
Subtracting 6048 from 6560 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Moving on to step 14:
The number 864 fits into 5120 5 times, leaving a remainder of 800.
Record the quotient 5 as the next digit in the result. 
Result so far: 42151.894675
If we subtract 4320 from 5120, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 15:
864 goes into 8000 9 times with a remainder of 224.
Use 9 as the next digit of our solution. 
Result so far: 42151.8946759
Subtract 7776 from 8000 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 16:
2240 divided by 864 is 2 with a remainder of 512.
Record the quotient 2 as the next digit in the result. 
Result so far: 42151.89467592
Deduct 1728 from 2240 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

The final result is 42151.89467592 with a remainder of 5.12e-07.
