We're dividing 5437861 by 865 
We want to divide 5437861 by 865.

On to step 1:
If we divide 5 by 865, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 865

Let's proceed to step 2:
The number 865 fits into 54 0 times, leaving a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 865

Going ahead to step 3:
865 goes into 543 0 times with a remainder of 543.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 543 after subtracting 0 from 543.
Append the next digit (7) from the dividend to 543 and continue with: 5437 / 865

Moving on to step 4:
When dividing 5437 by 865, we get 6 with a remainder of 247.
The next digit of our result is 6. 
Result so far: 6.0
If we take 5190 away from 5437, we end up with 247.
Bring next digit (8) of the dividend behind the 247 and repeat the process: 2478 / 865

Moving on to step 5:
When dividing 2478 by 865, we get 2 with a remainder of 748.
Put 2 as the next digit of the answer. 
Result so far: 62.0
Subtracting 1730 from 2478 leaves us with 748.
Bring next digit (6) of the dividend behind the 748 and repeat the process: 7486 / 865

Going ahead to step 6:
7486 divided by 865 is 8 with a remainder of 566.
Use 8 as the next digit of our solution. 
Result so far: 628.0
The remainder is 566 after subtracting 6920 from 7486.
Fetch the next digit (1) from the dividend, attach it to 566 and continue: 5661 / 865

Let's proceed to step 7:
If we divide 5661 by 865, we get 6 and a remainder of 471.
Use 6 as the next digit of our solution. 
Result so far: 6286.0
If we take 5190 away from 5661, we end up with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Let's proceed to step 8:
When dividing 4710 by 865, we get 5 with a remainder of 385.
Record the quotient 5 as the next digit in the result. 
Result so far: 6286.5
Subtracting 4325 from 4710 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 9:
3850 divided by 865 is 4 with a remainder of 390.
The number 4 becomes the next digit in our result. 
Result so far: 6286.54
Deduct 3460 from 3850 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 10:
The number 865 fits into 3900 4 times, leaving a remainder of 440.
The next digit of our result is 4. 
Result so far: 6286.544
Deduct 3460 from 3900 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final outcome is 6286.544, with a leftover of 0.044.
