42531445 divided by 865 
Let's see how many times 865 fits into 42531445.

Going ahead to step 1:
When dividing 4 by 865, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 865

On to step 2:
865 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 865

On to step 3:
425 divided by 865 is 0 with a remainder of 425.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 425 to get 425.
Append the next digit (3) from the dividend to 425 and continue with: 4253 / 865

Moving on to step 4:
If we divide 4253 by 865, we get 4 and a remainder of 793.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 793 after subtracting 3460 from 4253.
Grab the next digit (1) from the dividend, add it to 793, then carry on: 7931 / 865

Let's proceed to step 5:
If we divide 7931 by 865, we get 9 and a remainder of 146.
The next digit of our result is 9. 
Result so far: 49.0
Subtract 7785 from 7931 to get 146.
Bring next digit (4) of the dividend behind the 146 and repeat the process: 1464 / 865

On to step 6:
The number 865 fits into 1464 1 times, leaving a remainder of 599.
Put 1 as the next digit of the answer. 
Result so far: 491.0
The remainder is 599 after subtracting 865 from 1464.
Fetch the next digit (4) from the dividend, attach it to 599 and continue: 5994 / 865

Let's proceed to step 7:
865 can be fit into 5994 6 times, resulting in a remainder of 804.
The next digit of our result is 6. 
Result so far: 4916.0
The remainder is 804 after subtracting 5190 from 5994.
Fetch the next digit (5) from the dividend, attach it to 804 and continue: 8045 / 865

Advancing to step 8:
The number 865 fits into 8045 9 times, leaving a remainder of 260.
Use 9 as the next digit of our solution. 
Result so far: 49169.0
Deduct 7785 from 8045 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 9:
865 goes into 2600 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 49169.3
Subtracting 2595 from 2600 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
865 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 49169.3
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
865 goes into 500 0 times with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 49169.3
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 49169.3 with a remaining 0.05.
