We're dividing 40169328 by 864 
Let's see how many times 864 fits into 40169328.

Let's proceed to step 1:
864 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 864

Let's proceed to step 2:
864 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 864

Advancing to step 3:
If we divide 401 by 864, we get 0 and a remainder of 401.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 401 leaves us with 401.
Append the next digit (6) from the dividend to 401 and continue with: 4016 / 864

On to step 4:
864 goes into 4016 4 times with a remainder of 560.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 560 after subtracting 3456 from 4016.
Bring next digit (9) of the dividend behind the 560 and repeat the process: 5609 / 864

Advancing to step 5:
5609 divided by 864 is 6 with a remainder of 425.
The next digit of our result is 6. 
Result so far: 46.0
If we subtract 5184 from 5609, we get 425.
Fetch the next digit (3) from the dividend, attach it to 425 and continue: 4253 / 864

Going ahead to step 6:
864 goes into 4253 4 times with a remainder of 797.
The number 4 becomes the next digit in our result. 
Result so far: 464.0
Subtract 3456 from 4253 to get 797.
Grab the next digit (2) from the dividend, add it to 797, then carry on: 7972 / 864

Let's proceed to step 7:
864 can be fit into 7972 9 times, resulting in a remainder of 196.
The number 9 becomes the next digit in our result. 
Result so far: 4649.0
If we subtract 7776 from 7972, we get 196.
Bring next digit (8) of the dividend behind the 196 and repeat the process: 1968 / 864

Moving on to step 8:
If we divide 1968 by 864, we get 2 and a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 46492.0
Deduct 1728 from 1968 and we're left 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.

Let's proceed to step 9:
2400 divided by 864 is 2 with a remainder of 672.
Record the quotient 2 as the next digit in the result. 
Result so far: 46492.2
Deduct 1728 from 2400 and we're left 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.

Going ahead to step 10:
If we divide 6720 by 864, we get 7 and a remainder of 672.
The number 7 becomes the next digit in our result. 
Result so far: 46492.27
If we take 6048 away from 6720, 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.

Moving on to step 11:
864 goes into 6720 7 times with a remainder of 672.
Write down 7 as next digit of the result. 
Result so far: 46492.277
Subtract 6048 from 6720 to 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.

The final result is 46492.277 with a remainder of 0.0672.
