We look at the division of 13666597 by 907 
We want to figure out the number of times 13666597 can be divided by 907.

On to step 1:
907 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 907

Let's proceed to step 2:
If we divide 13 by 907, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 907

Advancing to step 3:
907 can be fit into 136 0 times, resulting in a remainder of 136.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 136 leaves us with 136.
Bring next digit (6) of the dividend behind the 136 and repeat the process: 1366 / 907

On to step 4:
The number 907 fits into 1366 1 times, leaving a remainder of 459.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 907 from 1366 to get 459.
Take the next digit (6) from the dividend and append it to 459, then repeat: 4596 / 907

Going ahead to step 5:
907 can be fit into 4596 5 times, resulting in a remainder of 61.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 61 after subtracting 4535 from 4596.
Grab the next digit (5) from the dividend, add it to 61, then carry on: 615 / 907

Going ahead to step 6:
907 goes into 615 0 times with a remainder of 615.
Write down 0 as next digit of the result. 
Result so far: 150.0
Subtracting 0 from 615 leaves us with 615.
Grab the next digit (9) from the dividend, add it to 615, then carry on: 6159 / 907

Let's proceed to step 7:
6159 divided by 907 is 6 with a remainder of 717.
Use 6 as the next digit of our solution. 
Result so far: 1506.0
Deduct 5442 from 6159 and we're left with 717.
Append the next digit (7) from the dividend to 717 and continue with: 7177 / 907

Advancing to step 8:
907 goes into 7177 7 times with a remainder of 828.
Write down 7 as next digit of the result. 
Result so far: 15067.0
If we take 6349 away from 7177, we end up with 828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

Advancing to step 9:
8280 divided by 907 is 9 with a remainder of 117.
Write down 9 as next digit of the result. 
Result so far: 15067.9
Subtracting 8163 from 8280 leaves us with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 10:
When dividing 1170 by 907, we get 1 with a remainder of 263.
The number 1 becomes the next digit in our result. 
Result so far: 15067.91
If we subtract 907 from 1170, we get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 11:
907 can be fit into 2630 2 times, resulting in a remainder of 816.
Put 2 as the next digit of the answer. 
Result so far: 15067.912
Subtract 1814 from 2630 to get 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Advancing to step 12:
8160 divided by 907 is 8 with a remainder of 904.
Record the quotient 8 as the next digit in the result. 
Result so far: 15067.9128
Subtract 7256 from 8160 to get 904.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9040, and continue the process.

Step 13:
The number 907 fits into 9040 9 times, leaving a remainder of 877.
Put 9 as the next digit of the answer. 
Result so far: 15067.91289
Deduct 8163 from 9040 and we're left with 877.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8770, and continue the process.

Going ahead to step 14:
8770 divided by 907 is 9 with a remainder of 607.
Write down 9 as next digit of the result. 
Result so far: 15067.912899
Subtracting 8163 from 8770 leaves us with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

The final result is 15067.912899 with a remainder of 6.07e-05.
