We divide 12307642 by 809
Let's see how many times 809 fits into 12307642.

Going ahead to step 1:
809 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 809

On to step 2:
12 divided by 809 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 809

Going ahead to step 3:
The number 809 fits into 123 0 times, leaving a remainder of 123.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 123, we end up with 123.
Include the next digit (0) from the dividend after 123, then repeat: 1230 / 809

On to step 4:
809 goes into 1230 1 times with a remainder of 421.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 421 after subtracting 809 from 1230.
Include the next digit (7) from the dividend after 421, then repeat: 4217 / 809

Step 5:
809 can be fit into 4217 5 times, resulting in a remainder of 172.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 4045 from 4217, we get 172.
Include the next digit (6) from the dividend after 172, then repeat: 1726 / 809

On to step 6:
If we divide 1726 by 809, we get 2 and a remainder of 108.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
Subtract 1618 from 1726 to get 108.
Append the next digit (4) from the dividend to 108 and continue with: 1084 / 809

Moving on to step 7:
809 goes into 1084 1 times with a remainder of 275.
Put 1 as the next digit of the answer. 
Result so far: 1521.0
If we subtract 809 from 1084, we get 275.
Append the next digit (2) from the dividend to 275 and continue with: 2752 / 809

Advancing to step 8:
2752 divided by 809 is 3 with a remainder of 325.
Write down 3 as next digit of the result. 
Result so far: 15213.0
The remainder is 325 after subtracting 2427 from 2752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 9:
The number 809 fits into 3250 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 15213.4
Deduct 3236 from 3250 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
If we divide 140 by 809, we get 0 and a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 15213.4
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 11:
When dividing 1400 by 809, we get 1 with a remainder of 591.
The number 1 becomes the next digit in our result. 
Result so far: 15213.401
Deduct 809 from 1400 and we're left with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Moving on to step 12:
The number 809 fits into 5910 7 times, leaving a remainder of 247.
Write down 7 as next digit of the result. 
Result so far: 15213.4017
Deduct 5663 from 5910 and we're left with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 13:
When dividing 2470 by 809, we get 3 with a remainder of 43.
The next digit of our result is 3. 
Result so far: 15213.40173
The remainder is 43 after subtracting 2427 from 2470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 14:
When dividing 430 by 809, we get 0 with a remainder of 430.
The next digit of our result is 0. 
Result so far: 15213.40173
Subtracting 0 from 430 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 15:
4300 divided by 809 is 5 with a remainder of 255.
Use 5 as the next digit of our solution. 
Result so far: 15213.4017305
The remainder is 255 after subtracting 4045 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 16:
If we divide 2550 by 809, we get 3 and a remainder of 123.
Put 3 as the next digit of the answer. 
Result so far: 15213.40173053
Subtracting 2427 from 2550 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

After the division, we end up with 15213.40173053 and a remainder of 1.23e-07.
