We look at the division of 7985928 by 680 
We're looking to find how many times 680 goes into 7985928.

Step 1:
7 divided by 680 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 680

Let's proceed to step 2:
The number 680 fits into 79 0 times, leaving a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Append the next digit (8) from the dividend to 79 and continue with: 798 / 680

On to step 3:
If we divide 798 by 680, we get 1 and a remainder of 118.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 680 away from 798, we end up with 118.
Fetch the next digit (5) from the dividend, attach it to 118 and continue: 1185 / 680

On to step 4:
680 can be fit into 1185 1 times, resulting in a remainder of 505.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 680 from 1185, we get 505.
Append the next digit (9) from the dividend to 505 and continue with: 5059 / 680

Advancing to step 5:
The number 680 fits into 5059 7 times, leaving a remainder of 299.
The next digit of our result is 7. 
Result so far: 117.0
Deduct 4760 from 5059 and we're left with 299.
Append the next digit (2) from the dividend to 299 and continue with: 2992 / 680

On to step 6:
The number 680 fits into 2992 4 times, leaving a remainder of 272.
Write down 4 as next digit of the result. 
Result so far: 1174.0
The remainder is 272 after subtracting 2720 from 2992.
Grab the next digit (8) from the dividend, add it to 272, then carry on: 2728 / 680

Step 7:
680 goes into 2728 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 11744.0
If we take 2720 away from 2728, we end up with 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 8:
680 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 11744.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 9:
680 can be fit into 800 1 times, resulting in a remainder of 120.
Record the quotient 1 as the next digit in the result. 
Result so far: 11744.01
The remainder is 120 after subtracting 680 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
680 can be fit into 1200 1 times, resulting in a remainder of 520.
Write down 1 as next digit of the result. 
Result so far: 11744.011
Subtract 680 from 1200 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Our division results in 11744.011 with a remaining 0.052.
