Let's divide 12698096 by 646
Let's see how many times 646 fits into 12698096.

Moving on to step 1:
When dividing 1 by 646, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 646

On to step 2:
646 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 646

Advancing to step 3:
126 divided by 646 is 0 with a remainder of 126.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 126, we end up with 126.
Append the next digit (9) from the dividend to 126 and continue with: 1269 / 646

Advancing to step 4:
The number 646 fits into 1269 1 times, leaving a remainder of 623.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 646 away from 1269, we end up with 623.
Bring next digit (8) of the dividend behind the 623 and repeat the process: 6238 / 646

Moving on to step 5:
646 goes into 6238 9 times with a remainder of 424.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 5814 from 6238 leaves us with 424.
Include the next digit (0) from the dividend after 424, then repeat: 4240 / 646

Let's proceed to step 6:
When dividing 4240 by 646, we get 6 with a remainder of 364.
Write down 6 as next digit of the result. 
Result so far: 196.0
Subtract 3876 from 4240 to get 364.
Grab the next digit (9) from the dividend, add it to 364, then carry on: 3649 / 646

Let's proceed to step 7:
646 goes into 3649 5 times with a remainder of 419.
Record the quotient 5 as the next digit in the result. 
Result so far: 1965.0
Subtract 3230 from 3649 to get 419.
Bring next digit (6) of the dividend behind the 419 and repeat the process: 4196 / 646

Step 8:
646 goes into 4196 6 times with a remainder of 320.
The next digit of our result is 6. 
Result so far: 19656.0
Deduct 3876 from 4196 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 9:
The number 646 fits into 3200 4 times, leaving a remainder of 616.
The number 4 becomes the next digit in our result. 
Result so far: 19656.4
Subtracting 2584 from 3200 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Going ahead to step 10:
The number 646 fits into 6160 9 times, leaving a remainder of 346.
Write down 9 as next digit of the result. 
Result so far: 19656.49
Subtracting 5814 from 6160 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Moving on to step 11:
The number 646 fits into 3460 5 times, leaving a remainder of 230.
The number 5 becomes the next digit in our result. 
Result so far: 19656.495
Subtracting 3230 from 3460 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 12:
2300 divided by 646 is 3 with a remainder of 362.
The number 3 becomes the next digit in our result. 
Result so far: 19656.4953
Subtract 1938 from 2300 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 13:
The number 646 fits into 3620 5 times, leaving a remainder of 390.
Put 5 as the next digit of the answer. 
Result so far: 19656.49535
Deduct 3230 from 3620 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 14:
646 goes into 3900 6 times with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 19656.495356
The remainder is 24 after subtracting 3876 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 15:
The number 646 fits into 240 0 times, leaving a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 19656.495356
If we subtract 0 from 240, 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.

Advancing to step 16:
2400 divided by 646 is 3 with a remainder of 462.
The number 3 becomes the next digit in our result. 
Result so far: 19656.49535603
If we take 1938 away from 2400, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

After the division, we end up with 19656.49535603 and a remainder of 4.62e-07.
