We look at the division of 6863610 by 859 
Let's see how many times 859 fits into 6863610.

Going ahead to step 1:
6 divided by 859 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 859

Let's proceed to step 2:
859 can be fit into 68 0 times, resulting in a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Take the next digit (6) from the dividend and append it to 68, then repeat: 686 / 859

Moving on to step 3:
859 can be fit into 686 0 times, resulting in a remainder of 686.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 686, we get 686.
Grab the next digit (3) from the dividend, add it to 686, then carry on: 6863 / 859

Step 4:
The number 859 fits into 6863 7 times, leaving a remainder of 850.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 6013 from 6863, we get 850.
Take the next digit (6) from the dividend and append it to 850, then repeat: 8506 / 859

On to step 5:
859 goes into 8506 9 times with a remainder of 775.
Write down 9 as next digit of the result. 
Result so far: 79.0
Deduct 7731 from 8506 and we're left with 775.
Bring next digit (1) of the dividend behind the 775 and repeat the process: 7751 / 859

On to step 6:
If we divide 7751 by 859, we get 9 and a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 799.0
Deduct 7731 from 7751 and we're left with 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 859

Step 7:
If we divide 200 by 859, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 7990.0
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 8:
2000 divided by 859 is 2 with a remainder of 282.
Put 2 as the next digit of the answer. 
Result so far: 7990.2
Subtracting 1718 from 2000 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Let's proceed to step 9:
2820 divided by 859 is 3 with a remainder of 243.
Record the quotient 3 as the next digit in the result. 
Result so far: 7990.23
Deduct 2577 from 2820 and we're left with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Advancing to step 10:
2430 divided by 859 is 2 with a remainder of 712.
Record the quotient 2 as the next digit in the result. 
Result so far: 7990.232
If we subtract 1718 from 2430, we get 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Going ahead to step 11:
7120 divided by 859 is 8 with a remainder of 248.
The number 8 becomes the next digit in our result. 
Result so far: 7990.2328
Subtract 6872 from 7120 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 12:
2480 divided by 859 is 2 with a remainder of 762.
Put 2 as the next digit of the answer. 
Result so far: 7990.23282
If we take 1718 away from 2480, we end up with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Moving on to step 13:
If we divide 7620 by 859, we get 8 and a remainder of 748.
Write down 8 as next digit of the result. 
Result so far: 7990.232828
Subtract 6872 from 7620 to get 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Step 14:
If we divide 7480 by 859, we get 8 and a remainder of 608.
Write down 8 as next digit of the result. 
Result so far: 7990.2328288
Subtract 6872 from 7480 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

The final outcome is 7990.2328288, with a leftover of 6.08e-06.
