57045445 divided by 864 
We want to divide 57045445 by 864.

Advancing to step 1:
If we divide 5 by 864, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 864

On to step 2:
The number 864 fits into 57 0 times, leaving a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Append the next digit (0) from the dividend to 57 and continue with: 570 / 864

Moving on to step 3:
570 divided by 864 is 0 with a remainder of 570.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 570 to get 570.
Include the next digit (4) from the dividend after 570, then repeat: 5704 / 864

On to step 4:
If we divide 5704 by 864, we get 6 and a remainder of 520.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 5184 away from 5704, we end up with 520.
Append the next digit (5) from the dividend to 520 and continue with: 5205 / 864

Step 5:
5205 divided by 864 is 6 with a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
If we take 5184 away from 5205, we end up with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 864

Step 6:
864 goes into 214 0 times with a remainder of 214.
Write down 0 as next digit of the result. 
Result so far: 660.0
The remainder is 214 after subtracting 0 from 214.
Grab the next digit (4) from the dividend, add it to 214, then carry on: 2144 / 864

Going ahead to step 7:
When dividing 2144 by 864, we get 2 with a remainder of 416.
Write down 2 as next digit of the result. 
Result so far: 6602.0
If we subtract 1728 from 2144, we get 416.
Grab the next digit (5) from the dividend, add it to 416, then carry on: 4165 / 864

Step 8:
4165 divided by 864 is 4 with a remainder of 709.
Put 4 as the next digit of the answer. 
Result so far: 66024.0
If we take 3456 away from 4165, we end up with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Let's proceed to step 9:
864 goes into 7090 8 times with a remainder of 178.
Put 8 as the next digit of the answer. 
Result so far: 66024.8
If we subtract 6912 from 7090, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 10:
1780 divided by 864 is 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 66024.82
Subtract 1728 from 1780 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 11:
If we divide 520 by 864, we get 0 and a remainder of 520.
The next digit of our result is 0. 
Result so far: 66024.82
The remainder is 520 after subtracting 0 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 12:
864 goes into 5200 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 66024.8206
Subtracting 5184 from 5200 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
The number 864 fits into 160 0 times, leaving a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 66024.8206
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
864 goes into 1600 1 times with a remainder of 736.
Record the quotient 1 as the next digit in the result. 
Result so far: 66024.820601
If we subtract 864 from 1600, we get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

On to step 15:
7360 divided by 864 is 8 with a remainder of 448.
The next digit of our result is 8. 
Result so far: 66024.8206018
If we subtract 6912 from 7360, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 16:
864 goes into 4480 5 times with a remainder of 160.
Put 5 as the next digit of the answer. 
Result so far: 66024.82060185
If we take 4320 away from 4480, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

In conclusion, the division gives 66024.82060185 with a balance of 1.6e-07.
