840103 ÷ 68 
We want to divide 840103 by 68.

On to step 1:
68 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 68

Going ahead to step 2:
The number 68 fits into 84 1 times, leaving a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 68 from 84 and we're left with 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 68

Advancing to step 3:
68 can be fit into 160 2 times, resulting in a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 136 away from 160, we end up with 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 68

On to step 4:
When dividing 241 by 68, we get 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Subtracting 204 from 241 leaves us with 37.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 68

Step 5:
68 goes into 370 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 1235.0
Subtract 340 from 370 to get 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 68

Moving on to step 6:
68 goes into 303 4 times with a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 12354.0
Deduct 272 from 303 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
If we divide 310 by 68, we get 4 and a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 12354.4
If we subtract 272 from 310, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
68 can be fit into 380 5 times, resulting in a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 12354.45
The remainder is 40 after subtracting 340 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
The number 68 fits into 400 5 times, leaving a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 12354.455
Subtracting 340 from 400 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 12354.455, and the remainder is 0.006.
