We're dividing 42374866 by 864 
Let's see how many times 864 fits into 42374866.

On to step 1:
When dividing 4 by 864, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 864

Advancing to step 2:
When dividing 42 by 864, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 864

Moving on to step 3:
When dividing 423 by 864, we get 0 with a remainder of 423.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 423, we end up with 423.
Include the next digit (7) from the dividend after 423, then repeat: 4237 / 864

Step 4:
864 goes into 4237 4 times with a remainder of 781.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 3456 from 4237 and we're left with 781.
Append the next digit (4) from the dividend to 781 and continue with: 7814 / 864

Moving on to step 5:
The number 864 fits into 7814 9 times, leaving a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 49.0
If we subtract 7776 from 7814, we get 38.
Bring next digit (8) of the dividend behind the 38 and repeat the process: 388 / 864

Going ahead to step 6:
864 can be fit into 388 0 times, resulting in a remainder of 388.
Put 0 as the next digit of the answer. 
Result so far: 490.0
If we take 0 away from 388, we end up with 388.
Append the next digit (6) from the dividend to 388 and continue with: 3886 / 864

Going ahead to step 7:
864 goes into 3886 4 times with a remainder of 430.
Write down 4 as next digit of the result. 
Result so far: 4904.0
Deduct 3456 from 3886 and we're left with 430.
Grab the next digit (6) from the dividend, add it to 430, then carry on: 4306 / 864

Let's proceed to step 8:
864 goes into 4306 4 times with a remainder of 850.
Put 4 as the next digit of the answer. 
Result so far: 49044.0
The remainder is 850 after subtracting 3456 from 4306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Going ahead to step 9:
864 goes into 8500 9 times with a remainder of 724.
Use 9 as the next digit of our solution. 
Result so far: 49044.9
If we subtract 7776 from 8500, we get 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Let's proceed to step 10:
If we divide 7240 by 864, we get 8 and a remainder of 328.
The next digit of our result is 8. 
Result so far: 49044.98
Subtracting 6912 from 7240 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 11:
864 goes into 3280 3 times with a remainder of 688.
Put 3 as the next digit of the answer. 
Result so far: 49044.983
Subtract 2592 from 3280 to get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Going ahead to step 12:
864 can be fit into 6880 7 times, resulting in a remainder of 832.
Use 7 as the next digit of our solution. 
Result so far: 49044.9837
If we take 6048 away from 6880, we end up with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Advancing to step 13:
864 can be fit into 8320 9 times, resulting in a remainder of 544.
Use 9 as the next digit of our solution. 
Result so far: 49044.98379
If we subtract 7776 from 8320, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Let's proceed to step 14:
5440 divided by 864 is 6 with a remainder of 256.
Record the quotient 6 as the next digit in the result. 
Result so far: 49044.983796
Subtract 5184 from 5440 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 15:
When dividing 2560 by 864, we get 2 with a remainder of 832.
The next digit of our result is 2. 
Result so far: 49044.9837962
If we take 1728 away from 2560, we end up with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

On to step 16:
864 can be fit into 8320 9 times, resulting in a remainder of 544.
Put 9 as the next digit of the answer. 
Result so far: 49044.98379629
Subtract 7776 from 8320 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

After the division, we end up with 49044.98379629 and a remainder of 5.44e-07.
