42641930 ÷ 864 
Let's see how many times 864 fits into 42641930.

Advancing to step 1:
864 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 864

Let's proceed to step 2:
When dividing 42 by 864, we get 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 864

Moving on to step 3:
The number 864 fits into 426 0 times, leaving a remainder of 426.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 426, we get 426.
Bring next digit (4) of the dividend behind the 426 and repeat the process: 4264 / 864

Going ahead to step 4:
864 can be fit into 4264 4 times, resulting in a remainder of 808.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 3456 from 4264, we get 808.
Take the next digit (1) from the dividend and append it to 808, then repeat: 8081 / 864

Let's proceed to step 5:
8081 divided by 864 is 9 with a remainder of 305.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Subtract 7776 from 8081 to get 305.
Take the next digit (9) from the dividend and append it to 305, then repeat: 3059 / 864

Advancing to step 6:
864 can be fit into 3059 3 times, resulting in a remainder of 467.
Write down 3 as next digit of the result. 
Result so far: 493.0
The remainder is 467 after subtracting 2592 from 3059.
Grab the next digit (3) from the dividend, add it to 467, then carry on: 4673 / 864

Let's proceed to step 7:
The number 864 fits into 4673 5 times, leaving a remainder of 353.
The next digit of our result is 5. 
Result so far: 4935.0
The remainder is 353 after subtracting 4320 from 4673.
Grab the next digit (0) from the dividend, add it to 353, then carry on: 3530 / 864

On to step 8:
864 can be fit into 3530 4 times, resulting in a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 49354.0
Subtracting 3456 from 3530 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 9:
When dividing 740 by 864, we get 0 with a remainder of 740.
The next digit of our result is 0. 
Result so far: 49354.0
Subtracting 0 from 740 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Advancing to step 10:
When dividing 7400 by 864, we get 8 with a remainder of 488.
The number 8 becomes the next digit in our result. 
Result so far: 49354.08
If we subtract 6912 from 7400, we get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Moving on to step 11:
4880 divided by 864 is 5 with a remainder of 560.
Record the quotient 5 as the next digit in the result. 
Result so far: 49354.085
Deduct 4320 from 4880 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 12:
If we divide 5600 by 864, we get 6 and a remainder of 416.
Record the quotient 6 as the next digit in the result. 
Result so far: 49354.0856
If we take 5184 away from 5600, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 13:
864 can be fit into 4160 4 times, resulting in a remainder of 704.
Record the quotient 4 as the next digit in the result. 
Result so far: 49354.08564
If we subtract 3456 from 4160, we get 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Advancing to step 14:
864 goes into 7040 8 times with a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 49354.085648
If we take 6912 away from 7040, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 15:
864 can be fit into 1280 1 times, resulting in a remainder of 416.
Use 1 as the next digit of our solution. 
Result so far: 49354.0856481
Deduct 864 from 1280 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 16:
When dividing 4160 by 864, we get 4 with a remainder of 704.
The next digit of our result is 4. 
Result so far: 49354.08564814
The remainder is 704 after subtracting 3456 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

The final outcome is 49354.08564814, with a leftover of 7.04e-07.
