Let's divide 12274829 by 787
Our goal is to divide 12274829 by 787.

On to step 1:
When dividing 1 by 787, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 787

Advancing to step 2:
When dividing 12 by 787, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 787

On to step 3:
787 goes into 122 0 times with a remainder of 122.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 122, we end up with 122.
Take the next digit (7) from the dividend and append it to 122, then repeat: 1227 / 787

Advancing to step 4:
787 can be fit into 1227 1 times, resulting in a remainder of 440.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 440 after subtracting 787 from 1227.
Grab the next digit (4) from the dividend, add it to 440, then carry on: 4404 / 787

Advancing to step 5:
The number 787 fits into 4404 5 times, leaving a remainder of 469.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 3935 from 4404 and we're left with 469.
Fetch the next digit (8) from the dividend, attach it to 469 and continue: 4698 / 787

On to step 6:
If we divide 4698 by 787, we get 5 and a remainder of 763.
The next digit of our result is 5. 
Result so far: 155.0
Subtracting 3935 from 4698 leaves us with 763.
Fetch the next digit (2) from the dividend, attach it to 763 and continue: 7632 / 787

Step 7:
The number 787 fits into 7632 9 times, leaving a remainder of 549.
The next digit of our result is 9. 
Result so far: 1559.0
The remainder is 549 after subtracting 7083 from 7632.
Take the next digit (9) from the dividend and append it to 549, then repeat: 5499 / 787

Step 8:
5499 divided by 787 is 6 with a remainder of 777.
Put 6 as the next digit of the answer. 
Result so far: 15596.0
If we take 4722 away from 5499, we end up with 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Step 9:
When dividing 7770 by 787, we get 9 with a remainder of 687.
Use 9 as the next digit of our solution. 
Result so far: 15596.9
If we subtract 7083 from 7770, we get 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

Advancing to step 10:
When dividing 6870 by 787, we get 8 with a remainder of 574.
Put 8 as the next digit of the answer. 
Result so far: 15596.98
If we take 6296 away from 6870, we end up with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Step 11:
When dividing 5740 by 787, we get 7 with a remainder of 231.
Put 7 as the next digit of the answer. 
Result so far: 15596.987
Subtracting 5509 from 5740 leaves us with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 12:
When dividing 2310 by 787, we get 2 with a remainder of 736.
The next digit of our result is 2. 
Result so far: 15596.9872
If we subtract 1574 from 2310, we get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Going ahead to step 13:
7360 divided by 787 is 9 with a remainder of 277.
Put 9 as the next digit of the answer. 
Result so far: 15596.98729
Subtract 7083 from 7360 to get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Moving on to step 14:
The number 787 fits into 2770 3 times, leaving a remainder of 409.
Use 3 as the next digit of our solution. 
Result so far: 15596.987293
Subtract 2361 from 2770 to get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Step 15:
787 goes into 4090 5 times with a remainder of 155.
The next digit of our result is 5. 
Result so far: 15596.9872935
Deduct 3935 from 4090 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 16:
If we divide 1550 by 787, we get 1 and a remainder of 763.
Record the quotient 1 as the next digit in the result. 
Result so far: 15596.98729351
Deduct 787 from 1550 and we're left with 763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7630, and continue the process.

The final result is 15596.98729351 with a remainder of 7.63e-07.
