45054757 divided by 864 
Our goal is to divide 45054757 by 864.

Let's proceed to step 1:
The number 864 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 864

On to step 2:
45 divided by 864 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 864

Advancing to step 3:
If we divide 450 by 864, we get 0 and a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 450 and we're left with 450.
Bring next digit (5) of the dividend behind the 450 and repeat the process: 4505 / 864

Advancing to step 4:
When dividing 4505 by 864, we get 5 with a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 185 after subtracting 4320 from 4505.
Grab the next digit (4) from the dividend, add it to 185, then carry on: 1854 / 864

Let's proceed to step 5:
864 can be fit into 1854 2 times, resulting in a remainder of 126.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtracting 1728 from 1854 leaves us with 126.
Include the next digit (7) from the dividend after 126, then repeat: 1267 / 864

On to step 6:
864 can be fit into 1267 1 times, resulting in a remainder of 403.
The next digit of our result is 1. 
Result so far: 521.0
The remainder is 403 after subtracting 864 from 1267.
Fetch the next digit (5) from the dividend, attach it to 403 and continue: 4035 / 864

Moving on to step 7:
If we divide 4035 by 864, we get 4 and a remainder of 579.
Record the quotient 4 as the next digit in the result. 
Result so far: 5214.0
If we subtract 3456 from 4035, we get 579.
Grab the next digit (7) from the dividend, add it to 579, then carry on: 5797 / 864

Moving on to step 8:
The number 864 fits into 5797 6 times, leaving a remainder of 613.
Write down 6 as next digit of the result. 
Result so far: 52146.0
The remainder is 613 after subtracting 5184 from 5797.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Going ahead to step 9:
6130 divided by 864 is 7 with a remainder of 82.
Put 7 as the next digit of the answer. 
Result so far: 52146.7
If we take 6048 away from 6130, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 10:
864 goes into 820 0 times with a remainder of 820.
The next digit of our result is 0. 
Result so far: 52146.7
The remainder is 820 after subtracting 0 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Step 11:
8200 divided by 864 is 9 with a remainder of 424.
The next digit of our result is 9. 
Result so far: 52146.709
Subtract 7776 from 8200 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 12:
If we divide 4240 by 864, we get 4 and a remainder of 784.
The number 4 becomes the next digit in our result. 
Result so far: 52146.7094
Deduct 3456 from 4240 and we're left with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Advancing to step 13:
864 can be fit into 7840 9 times, resulting in a remainder of 64.
The number 9 becomes the next digit in our result. 
Result so far: 52146.70949
The remainder is 64 after subtracting 7776 from 7840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 14:
If we divide 640 by 864, we get 0 and a remainder of 640.
The next digit of our result is 0. 
Result so far: 52146.70949
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 15:
6400 divided by 864 is 7 with a remainder of 352.
Write down 7 as next digit of the result. 
Result so far: 52146.7094907
If we subtract 6048 from 6400, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 16:
864 goes into 3520 4 times with a remainder of 64.
The next digit of our result is 4. 
Result so far: 52146.70949074
If we subtract 3456 from 3520, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 52146.70949074, with a leftover of 6.4e-08.
