We look at the division of 869903 by 68 
Let's see how many times 68 fits into 869903.

Step 1:
When dividing 8 by 68, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 68

Step 2:
When dividing 86 by 68, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 68 from 86 and we're left with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 68

Step 3:
If we divide 189 by 68, we get 2 and a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 136 away from 189, we end up with 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 68

On to step 4:
If we divide 539 by 68, we get 7 and a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 127.0
The remainder is 63 after subtracting 476 from 539.
Bring next digit (0) of the dividend behind the 63 and repeat the process: 630 / 68

Moving on to step 5:
68 goes into 630 9 times with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 1279.0
If we subtract 612 from 630, we get 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 68

Moving on to step 6:
183 divided by 68 is 2 with a remainder of 47.
Write down 2 as next digit of the result. 
Result so far: 12792.0
If we subtract 136 from 183, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
If we divide 470 by 68, we get 6 and a remainder of 62.
The next digit of our result is 6. 
Result so far: 12792.6
The remainder is 62 after subtracting 408 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 8:
68 can be fit into 620 9 times, resulting in a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 12792.69
If we subtract 612 from 620, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
80 divided by 68 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 12792.691
If we subtract 68 from 80, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
The number 68 fits into 120 1 times, leaving a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 12792.6911
Subtracting 68 from 120 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 12792.6911 with a remaining 0.00052.
