Let's divide 31184691 by 680
We want to figure out the number of times 31184691 can be divided by 680.

Step 1:
When dividing 3 by 680, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 680

Going ahead to step 2:
31 divided by 680 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 680

Going ahead to step 3:
The number 680 fits into 311 0 times, leaving a remainder of 311.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 311 after subtracting 0 from 311.
Include the next digit (8) from the dividend after 311, then repeat: 3118 / 680

On to step 4:
3118 divided by 680 is 4 with a remainder of 398.
The next digit of our result is 4. 
Result so far: 4.0
If we take 2720 away from 3118, we end up with 398.
Include the next digit (4) from the dividend after 398, then repeat: 3984 / 680

Moving on to step 5:
If we divide 3984 by 680, we get 5 and a remainder of 584.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Deduct 3400 from 3984 and we're left with 584.
Include the next digit (6) from the dividend after 584, then repeat: 5846 / 680

On to step 6:
680 goes into 5846 8 times with a remainder of 406.
Use 8 as the next digit of our solution. 
Result so far: 458.0
If we subtract 5440 from 5846, we get 406.
Fetch the next digit (9) from the dividend, attach it to 406 and continue: 4069 / 680

Moving on to step 7:
The number 680 fits into 4069 5 times, leaving a remainder of 669.
Use 5 as the next digit of our solution. 
Result so far: 4585.0
If we take 3400 away from 4069, we end up with 669.
Take the next digit (1) from the dividend and append it to 669, then repeat: 6691 / 680

Step 8:
6691 divided by 680 is 9 with a remainder of 571.
The next digit of our result is 9. 
Result so far: 45859.0
If we take 6120 away from 6691, we end up with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Moving on to step 9:
If we divide 5710 by 680, we get 8 and a remainder of 270.
The next digit of our result is 8. 
Result so far: 45859.8
Deduct 5440 from 5710 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 10:
When dividing 2700 by 680, we get 3 with a remainder of 660.
Use 3 as the next digit of our solution. 
Result so far: 45859.83
Subtracting 2040 from 2700 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 11:
680 goes into 6600 9 times with a remainder of 480.
The number 9 becomes the next digit in our result. 
Result so far: 45859.839
Subtracting 6120 from 6600 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 12:
If we divide 4800 by 680, we get 7 and a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 45859.8397
If we take 4760 away from 4800, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
680 can be fit into 400 0 times, resulting in a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 45859.8397
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 14:
680 can be fit into 4000 5 times, resulting in a remainder of 600.
The number 5 becomes the next digit in our result. 
Result so far: 45859.839705
Subtracting 3400 from 4000 leaves us 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.

Let's proceed to step 15:
680 goes into 6000 8 times with a remainder of 560.
The number 8 becomes the next digit in our result. 
Result so far: 45859.8397058
If we subtract 5440 from 6000, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 16:
If we divide 5600 by 680, we get 8 and a remainder of 160.
The next digit of our result is 8. 
Result so far: 45859.83970588
Subtract 5440 from 5600 to 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.

The final result is 45859.83970588 with a remainder of 1.6e-07.
