6391830 ÷ 868 
We want to divide 6391830 by 868.

On to step 1:
6 divided by 868 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 868

Advancing to step 2:
63 divided by 868 is 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 868

Let's proceed to step 3:
868 goes into 639 0 times with a remainder of 639.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 639, we end up with 639.
Grab the next digit (1) from the dividend, add it to 639, then carry on: 6391 / 868

Step 4:
If we divide 6391 by 868, we get 7 and a remainder of 315.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 6076 from 6391 leaves us with 315.
Append the next digit (8) from the dividend to 315 and continue with: 3158 / 868

Let's proceed to step 5:
3158 divided by 868 is 3 with a remainder of 554.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtracting 2604 from 3158 leaves us with 554.
Bring next digit (3) of the dividend behind the 554 and repeat the process: 5543 / 868

Going ahead to step 6:
868 can be fit into 5543 6 times, resulting in a remainder of 335.
Record the quotient 6 as the next digit in the result. 
Result so far: 736.0
The remainder is 335 after subtracting 5208 from 5543.
Grab the next digit (0) from the dividend, add it to 335, then carry on: 3350 / 868

On to step 7:
When dividing 3350 by 868, we get 3 with a remainder of 746.
Write down 3 as next digit of the result. 
Result so far: 7363.0
Subtracting 2604 from 3350 leaves us with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

On to step 8:
If we divide 7460 by 868, we get 8 and a remainder of 516.
Use 8 as the next digit of our solution. 
Result so far: 7363.8
The remainder is 516 after subtracting 6944 from 7460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Going ahead to step 9:
The number 868 fits into 5160 5 times, leaving a remainder of 820.
Record the quotient 5 as the next digit in the result. 
Result so far: 7363.85
If we take 4340 away from 5160, we end up with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Going ahead to step 10:
8200 divided by 868 is 9 with a remainder of 388.
The next digit of our result is 9. 
Result so far: 7363.859
Subtracting 7812 from 8200 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 11:
3880 divided by 868 is 4 with a remainder of 408.
Put 4 as the next digit of the answer. 
Result so far: 7363.8594
The remainder is 408 after subtracting 3472 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 12:
The number 868 fits into 4080 4 times, leaving a remainder of 608.
Put 4 as the next digit of the answer. 
Result so far: 7363.85944
Subtracting 3472 from 4080 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Our division results in 7363.85944 with a remaining 0.000608.
