We look at the division of 49238891 by 864 
Let's see how many times 864 fits into 49238891.

Advancing to step 1:
864 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 864

Advancing to step 2:
49 divided by 864 is 0 with a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Take the next digit (2) from the dividend and append it to 49, then repeat: 492 / 864

Advancing to step 3:
864 can be fit into 492 0 times, resulting in a remainder of 492.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 492 and we're left with 492.
Grab the next digit (3) from the dividend, add it to 492, then carry on: 4923 / 864

Let's proceed to step 4:
4923 divided by 864 is 5 with a remainder of 603.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 4320 from 4923 leaves us with 603.
Bring next digit (8) of the dividend behind the 603 and repeat the process: 6038 / 864

Step 5:
When dividing 6038 by 864, we get 6 with a remainder of 854.
The next digit of our result is 6. 
Result so far: 56.0
If we subtract 5184 from 6038, we get 854.
Bring next digit (8) of the dividend behind the 854 and repeat the process: 8548 / 864

Going ahead to step 6:
864 can be fit into 8548 9 times, resulting in a remainder of 772.
Put 9 as the next digit of the answer. 
Result so far: 569.0
Subtract 7776 from 8548 to get 772.
Include the next digit (9) from the dividend after 772, then repeat: 7729 / 864

Let's proceed to step 7:
The number 864 fits into 7729 8 times, leaving a remainder of 817.
Write down 8 as next digit of the result. 
Result so far: 5698.0
Subtract 6912 from 7729 to get 817.
Include the next digit (1) from the dividend after 817, then repeat: 8171 / 864

Going ahead to step 8:
864 can be fit into 8171 9 times, resulting in a remainder of 395.
Put 9 as the next digit of the answer. 
Result so far: 56989.0
If we subtract 7776 from 8171, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Step 9:
If we divide 3950 by 864, we get 4 and a remainder of 494.
The number 4 becomes the next digit in our result. 
Result so far: 56989.4
If we take 3456 away from 3950, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Step 10:
4940 divided by 864 is 5 with a remainder of 620.
Put 5 as the next digit of the answer. 
Result so far: 56989.45
If we subtract 4320 from 4940, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 11:
The number 864 fits into 6200 7 times, leaving a remainder of 152.
Record the quotient 7 as the next digit in the result. 
Result so far: 56989.457
The remainder is 152 after subtracting 6048 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 12:
When dividing 1520 by 864, we get 1 with a remainder of 656.
Record the quotient 1 as the next digit in the result. 
Result so far: 56989.4571
Subtracting 864 from 1520 leaves us with 656.
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:
When dividing 6560 by 864, we get 7 with a remainder of 512.
Write down 7 as next digit of the result. 
Result so far: 56989.45717
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.

On to step 14:
The number 864 fits into 5120 5 times, leaving a remainder of 800.
Use 5 as the next digit of our solution. 
Result so far: 56989.457175
The remainder is 800 after subtracting 4320 from 5120.
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.
Write down 9 as next digit of the result. 
Result so far: 56989.4571759
Deduct 7776 from 8000 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 16:
The number 864 fits into 2240 2 times, leaving a remainder of 512.
Record the quotient 2 as the next digit in the result. 
Result so far: 56989.45717592
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 quotient of the division is 56989.45717592, and the remainder is 5.12e-07.
