We're dividing 68520990 by 102 
We're looking to find how many times 102 goes into 68520990.

Step 1:
6 divided by 102 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 102

Advancing to step 2:
The number 102 fits into 68 0 times, leaving a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Grab the next digit (5) from the dividend, add it to 68, then carry on: 685 / 102

On to step 3:
The number 102 fits into 685 6 times, leaving a remainder of 73.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 612 from 685, we get 73.
Fetch the next digit (2) from the dividend, attach it to 73 and continue: 732 / 102

Advancing to step 4:
732 divided by 102 is 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Subtracting 714 from 732 leaves us with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 102

Moving on to step 5:
If we divide 180 by 102, we get 1 and a remainder of 78.
Use 1 as the next digit of our solution. 
Result so far: 671.0
The remainder is 78 after subtracting 102 from 180.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 102

Going ahead to step 6:
The number 102 fits into 789 7 times, leaving a remainder of 75.
The next digit of our result is 7. 
Result so far: 6717.0
The remainder is 75 after subtracting 714 from 789.
Grab the next digit (9) from the dividend, add it to 75, then carry on: 759 / 102

On to step 7:
If we divide 759 by 102, we get 7 and a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 67177.0
If we take 714 away from 759, we end up with 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 102

Advancing to step 8:
When dividing 450 by 102, we get 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 671774.0
Deduct 408 from 450 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
When dividing 420 by 102, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 671774.4
If we subtract 408 from 420, 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.

On to step 10:
102 goes into 120 1 times with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 671774.41
If we subtract 102 from 120, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
The number 102 fits into 180 1 times, leaving a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 671774.411
If we subtract 102 from 180, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final outcome is 671774.411, with a leftover of 0.0078.
