Let's divide 80964002 by 680
We're looking to find how many times 680 goes into 80964002.

Going ahead to step 1:
If we divide 8 by 680, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 680

On to step 2:
The number 680 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 680

Let's proceed to step 3:
680 goes into 809 1 times with a remainder of 129.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 680 from 809 and we're left with 129.
Grab the next digit (6) from the dividend, add it to 129, then carry on: 1296 / 680

On to step 4:
1296 divided by 680 is 1 with a remainder of 616.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 680 from 1296 and we're left with 616.
Fetch the next digit (4) from the dividend, attach it to 616 and continue: 6164 / 680

Let's proceed to step 5:
6164 divided by 680 is 9 with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
The remainder is 44 after subtracting 6120 from 6164.
Append the next digit (0) from the dividend to 44 and continue with: 440 / 680

Step 6:
680 goes into 440 0 times with a remainder of 440.
The next digit of our result is 0. 
Result so far: 1190.0
The remainder is 440 after subtracting 0 from 440.
Take the next digit (0) from the dividend and append it to 440, then repeat: 4400 / 680

Going ahead to step 7:
680 goes into 4400 6 times with a remainder of 320.
Record the quotient 6 as the next digit in the result. 
Result so far: 11906.0
If we subtract 4080 from 4400, we get 320.
Take the next digit (2) from the dividend and append it to 320, then repeat: 3202 / 680

Advancing to step 8:
680 goes into 3202 4 times with a remainder of 482.
Use 4 as the next digit of our solution. 
Result so far: 119064.0
Subtracting 2720 from 3202 leaves us with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

On to step 9:
680 can be fit into 4820 7 times, resulting in a remainder of 60.
The next digit of our result is 7. 
Result so far: 119064.7
If we subtract 4760 from 4820, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
680 can be fit into 600 0 times, resulting in a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 119064.7
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 11:
When dividing 6000 by 680, we get 8 with a remainder of 560.
Use 8 as the next digit of our solution. 
Result so far: 119064.708
Subtracting 5440 from 6000 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 12:
5600 divided by 680 is 8 with a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 119064.7088
If we subtract 5440 from 5600, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

After the division, we end up with 119064.7088 and a remainder of 0.0016.
