Let's divide 39156888 by 868
Our goal is to divide 39156888 by 868.

Advancing to step 1:
If we divide 3 by 868, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 868

Moving on to step 2:
868 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 868

Moving on to step 3:
The number 868 fits into 391 0 times, leaving a remainder of 391.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 391 after subtracting 0 from 391.
Grab the next digit (5) from the dividend, add it to 391, then carry on: 3915 / 868

Going ahead to step 4:
868 can be fit into 3915 4 times, resulting in a remainder of 443.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 3472 from 3915 leaves us with 443.
Take the next digit (6) from the dividend and append it to 443, then repeat: 4436 / 868

Let's proceed to step 5:
868 can be fit into 4436 5 times, resulting in a remainder of 96.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we subtract 4340 from 4436, we get 96.
Append the next digit (8) from the dividend to 96 and continue with: 968 / 868

Advancing to step 6:
When dividing 968 by 868, we get 1 with a remainder of 100.
The number 1 becomes the next digit in our result. 
Result so far: 451.0
Deduct 868 from 968 and we're left with 100.
Bring next digit (8) of the dividend behind the 100 and repeat the process: 1008 / 868

Moving on to step 7:
868 can be fit into 1008 1 times, resulting in a remainder of 140.
Write down 1 as next digit of the result. 
Result so far: 4511.0
If we take 868 away from 1008, we end up with 140.
Bring next digit (8) of the dividend behind the 140 and repeat the process: 1408 / 868

Step 8:
If we divide 1408 by 868, we get 1 and a remainder of 540.
Record the quotient 1 as the next digit in the result. 
Result so far: 45111.0
If we subtract 868 from 1408, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 9:
If we divide 5400 by 868, we get 6 and a remainder of 192.
The number 6 becomes the next digit in our result. 
Result so far: 45111.6
The remainder is 192 after subtracting 5208 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 10:
868 goes into 1920 2 times with a remainder of 184.
The next digit of our result is 2. 
Result so far: 45111.62
The remainder is 184 after subtracting 1736 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 11:
The number 868 fits into 1840 2 times, leaving a remainder of 104.
The next digit of our result is 2. 
Result so far: 45111.622
The remainder is 104 after subtracting 1736 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

After the division, we end up with 45111.622 and a remainder of 0.0104.
