Let's divide 80115749 by 68
We want to figure out the number of times 80115749 can be divided by 68.

Step 1:
8 divided by 68 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 68

Step 2:
68 goes into 80 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 68 from 80, we get 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 68

Advancing to step 3:
If we divide 121 by 68, we get 1 and a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 68 from 121 leaves us with 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 68

Step 4:
531 divided by 68 is 7 with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 117.0
Subtracting 476 from 531 leaves us with 55.
Bring next digit (5) of the dividend behind the 55 and repeat the process: 555 / 68

On to step 5:
When dividing 555 by 68, we get 8 with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 1178.0
If we subtract 544 from 555, we get 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 68

Moving on to step 6:
When dividing 117 by 68, we get 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 11781.0
If we subtract 68 from 117, we get 49.
Bring next digit (4) of the dividend behind the 49 and repeat the process: 494 / 68

On to step 7:
494 divided by 68 is 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 117817.0
Deduct 476 from 494 and we're left with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 68

Moving on to step 8:
If we divide 189 by 68, we get 2 and a remainder of 53.
The number 2 becomes the next digit in our result. 
Result so far: 1178172.0
If we take 136 away from 189, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 9:
When dividing 530 by 68, we get 7 with a remainder of 54.
The next digit of our result is 7. 
Result so far: 1178172.7
If we subtract 476 from 530, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 10:
When dividing 540 by 68, we get 7 with a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 1178172.77
Subtract 476 from 540 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 1178172.77 and a remainder of 0.064.
