Let's divide 12393667 by 909
We want to figure out the number of times 12393667 can be divided by 909.

Moving on to step 1:
909 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 909

Advancing to step 2:
909 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 909

Let's proceed to step 3:
909 can be fit into 123 0 times, resulting in a remainder of 123.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 123, we end up with 123.
Grab the next digit (9) from the dividend, add it to 123, then carry on: 1239 / 909

Step 4:
When dividing 1239 by 909, we get 1 with a remainder of 330.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 330 after subtracting 909 from 1239.
Fetch the next digit (3) from the dividend, attach it to 330 and continue: 3303 / 909

Advancing to step 5:
The number 909 fits into 3303 3 times, leaving a remainder of 576.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 2727 away from 3303, we end up with 576.
Fetch the next digit (6) from the dividend, attach it to 576 and continue: 5766 / 909

On to step 6:
The number 909 fits into 5766 6 times, leaving a remainder of 312.
Use 6 as the next digit of our solution. 
Result so far: 136.0
The remainder is 312 after subtracting 5454 from 5766.
Fetch the next digit (6) from the dividend, attach it to 312 and continue: 3126 / 909

On to step 7:
3126 divided by 909 is 3 with a remainder of 399.
Record the quotient 3 as the next digit in the result. 
Result so far: 1363.0
If we subtract 2727 from 3126, we get 399.
Bring next digit (7) of the dividend behind the 399 and repeat the process: 3997 / 909

Let's proceed to step 8:
3997 divided by 909 is 4 with a remainder of 361.
Write down 4 as next digit of the result. 
Result so far: 13634.0
Subtracting 3636 from 3997 leaves us with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Advancing to step 9:
If we divide 3610 by 909, we get 3 and a remainder of 883.
The number 3 becomes the next digit in our result. 
Result so far: 13634.3
Deduct 2727 from 3610 and we're left with 883.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8830, and continue the process.

Let's proceed to step 10:
The number 909 fits into 8830 9 times, leaving a remainder of 649.
Put 9 as the next digit of the answer. 
Result so far: 13634.39
Subtracting 8181 from 8830 leaves us with 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Step 11:
If we divide 6490 by 909, we get 7 and a remainder of 127.
Put 7 as the next digit of the answer. 
Result so far: 13634.397
Subtracting 6363 from 6490 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

On to step 12:
909 goes into 1270 1 times with a remainder of 361.
Record the quotient 1 as the next digit in the result. 
Result so far: 13634.3971
Deduct 909 from 1270 and we're left with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Let's proceed to step 13:
909 can be fit into 3610 3 times, resulting in a remainder of 883.
Write down 3 as next digit of the result. 
Result so far: 13634.39713
If we subtract 2727 from 3610, we get 883.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8830, and continue the process.

Moving on to step 14:
When dividing 8830 by 909, we get 9 with a remainder of 649.
The next digit of our result is 9. 
Result so far: 13634.397139
Subtract 8181 from 8830 to get 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Step 15:
909 goes into 6490 7 times with a remainder of 127.
The next digit of our result is 7. 
Result so far: 13634.3971397
If we subtract 6363 from 6490, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 16:
1270 divided by 909 is 1 with a remainder of 361.
The next digit of our result is 1. 
Result so far: 13634.39713971
If we take 909 away from 1270, we end up with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

The final outcome is 13634.39713971, with a leftover of 3.61e-07.
