54816423 divided by 864 
Our goal is to divide 54816423 by 864.

Going ahead to step 1:
864 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 864

Advancing to step 2:
864 can be fit into 54 0 times, resulting in a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 864

Step 3:
548 divided by 864 is 0 with a remainder of 548.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 548 and we're left with 548.
Grab the next digit (1) from the dividend, add it to 548, then carry on: 5481 / 864

Advancing to step 4:
If we divide 5481 by 864, we get 6 and a remainder of 297.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 5184 from 5481 and we're left with 297.
Take the next digit (6) from the dividend and append it to 297, then repeat: 2976 / 864

Moving on to step 5:
When dividing 2976 by 864, we get 3 with a remainder of 384.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
If we take 2592 away from 2976, we end up with 384.
Append the next digit (4) from the dividend to 384 and continue with: 3844 / 864

Let's proceed to step 6:
If we divide 3844 by 864, we get 4 and a remainder of 388.
Put 4 as the next digit of the answer. 
Result so far: 634.0
If we subtract 3456 from 3844, we get 388.
Bring next digit (2) of the dividend behind the 388 and repeat the process: 3882 / 864

Let's proceed to step 7:
The number 864 fits into 3882 4 times, leaving a remainder of 426.
Put 4 as the next digit of the answer. 
Result so far: 6344.0
If we subtract 3456 from 3882, we get 426.
Include the next digit (3) from the dividend after 426, then repeat: 4263 / 864

Step 8:
When dividing 4263 by 864, we get 4 with a remainder of 807.
The number 4 becomes the next digit in our result. 
Result so far: 63444.0
Deduct 3456 from 4263 and we're left with 807.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8070, and continue the process.

Going ahead to step 9:
864 can be fit into 8070 9 times, resulting in a remainder of 294.
Write down 9 as next digit of the result. 
Result so far: 63444.9
Deduct 7776 from 8070 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 10:
864 can be fit into 2940 3 times, resulting in a remainder of 348.
The number 3 becomes the next digit in our result. 
Result so far: 63444.93
If we subtract 2592 from 2940, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 11:
864 goes into 3480 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 63444.934
Deduct 3456 from 3480 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
240 divided by 864 is 0 with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 63444.934
Deduct 0 from 240 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.

On to step 13:
864 goes into 2400 2 times with a remainder of 672.
The number 2 becomes the next digit in our result. 
Result so far: 63444.93402
Subtracting 1728 from 2400 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.

On to step 14:
If we divide 6720 by 864, we get 7 and a remainder of 672.
Write down 7 as next digit of the result. 
Result so far: 63444.934027
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.

Let's proceed to step 15:
864 can be fit into 6720 7 times, resulting in a remainder of 672.
The number 7 becomes the next digit in our result. 
Result so far: 63444.9340277
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.

The final result is 63444.9340277 with a remainder of 6.72e-06.
