We divide 42661345 by 864
We want to divide 42661345 by 864.

Let's proceed to step 1:
When dividing 4 by 864, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 864

Let's proceed to step 2:
42 divided by 864 is 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 864

Moving on to step 3:
When dividing 426 by 864, we get 0 with a remainder of 426.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 426, we end up with 426.
Bring next digit (6) of the dividend behind the 426 and repeat the process: 4266 / 864

Moving on to step 4:
864 goes into 4266 4 times with a remainder of 810.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3456 away from 4266, we end up with 810.
Include the next digit (1) from the dividend after 810, then repeat: 8101 / 864

Moving on to step 5:
If we divide 8101 by 864, we get 9 and a remainder of 325.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Subtracting 7776 from 8101 leaves us with 325.
Grab the next digit (3) from the dividend, add it to 325, then carry on: 3253 / 864

On to step 6:
The number 864 fits into 3253 3 times, leaving a remainder of 661.
Put 3 as the next digit of the answer. 
Result so far: 493.0
If we take 2592 away from 3253, we end up with 661.
Grab the next digit (4) from the dividend, add it to 661, then carry on: 6614 / 864

On to step 7:
The number 864 fits into 6614 7 times, leaving a remainder of 566.
The next digit of our result is 7. 
Result so far: 4937.0
Subtract 6048 from 6614 to get 566.
Fetch the next digit (5) from the dividend, attach it to 566 and continue: 5665 / 864

Advancing to step 8:
When dividing 5665 by 864, we get 6 with a remainder of 481.
The next digit of our result is 6. 
Result so far: 49376.0
If we take 5184 away from 5665, we end up with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Advancing to step 9:
864 can be fit into 4810 5 times, resulting in a remainder of 490.
Use 5 as the next digit of our solution. 
Result so far: 49376.5
Subtract 4320 from 4810 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 10:
The number 864 fits into 4900 5 times, leaving a remainder of 580.
Write down 5 as next digit of the result. 
Result so far: 49376.55
The remainder is 580 after subtracting 4320 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

The final result is 49376.55 with a remainder of 0.58.
