We're dividing 81491290 by 680 
We're looking to find how many times 680 goes into 81491290.

On to step 1:
8 divided by 680 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 680

Step 2:
When dividing 81 by 680, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Include the next digit (4) from the dividend after 81, then repeat: 814 / 680

Let's proceed to step 3:
The number 680 fits into 814 1 times, leaving a remainder of 134.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 680 from 814 and we're left with 134.
Take the next digit (9) from the dividend and append it to 134, then repeat: 1349 / 680

Going ahead to step 4:
680 goes into 1349 1 times with a remainder of 669.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 680 from 1349 leaves us with 669.
Include the next digit (1) from the dividend after 669, then repeat: 6691 / 680

Going ahead to step 5:
The number 680 fits into 6691 9 times, leaving a remainder of 571.
Write down 9 as next digit of the result. 
Result so far: 119.0
The remainder is 571 after subtracting 6120 from 6691.
Take the next digit (2) from the dividend and append it to 571, then repeat: 5712 / 680

Going ahead to step 6:
If we divide 5712 by 680, we get 8 and a remainder of 272.
Use 8 as the next digit of our solution. 
Result so far: 1198.0
If we take 5440 away from 5712, we end up with 272.
Take the next digit (9) from the dividend and append it to 272, then repeat: 2729 / 680

Let's proceed to step 7:
2729 divided by 680 is 4 with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 11984.0
Deduct 2720 from 2729 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 680

Let's proceed to step 8:
When dividing 90 by 680, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 119840.0
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 9:
680 goes into 900 1 times with a remainder of 220.
Write down 1 as next digit of the result. 
Result so far: 119840.1
The remainder is 220 after subtracting 680 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 10:
When dividing 2200 by 680, we get 3 with a remainder of 160.
Use 3 as the next digit of our solution. 
Result so far: 119840.13
Subtracting 2040 from 2200 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 11:
The number 680 fits into 1600 2 times, leaving a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 119840.132
If we subtract 1360 from 1600, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 12:
680 goes into 2400 3 times with a remainder of 360.
Write down 3 as next digit of the result. 
Result so far: 119840.1323
Subtracting 2040 from 2400 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 13:
3600 divided by 680 is 5 with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 119840.13235
Deduct 3400 from 3600 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 14:
680 can be fit into 2000 2 times, resulting in a remainder of 640.
The next digit of our result is 2. 
Result so far: 119840.132352
Subtracting 1360 from 2000 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 15:
When dividing 6400 by 680, we get 9 with a remainder of 280.
Put 9 as the next digit of the answer. 
Result so far: 119840.1323529
Subtracting 6120 from 6400 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 16:
680 goes into 2800 4 times with a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 119840.13235294
Deduct 2720 from 2800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 119840.13235294 with a remaining 8e-08.
