Moving on to step 1:
907 goes into 1 0 times 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.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 907

On to step 2:
13 divided by 907 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 907

Advancing to step 3:
The number 907 fits into 131 0 times, leaving a remainder of 131.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 131 leaves us with 131.
Include the next digit (8) from the dividend after 131, then repeat: 1318 / 907

Going ahead to step 4:
When dividing 1318 by 907, we get 1 with a remainder of 411.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 907 from 1318 to get 411.
Append the next digit (8) from the dividend to 411 and continue with: 4118 / 907

Step 5:
When dividing 4118 by 907, we get 4 with a remainder of 490.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 3628 from 4118 and we're left with 490.
Fetch the next digit (7) from the dividend, attach it to 490 and continue: 4907 / 907

Advancing to step 6:
If we divide 4907 by 907, we get 5 and a remainder of 372.
The next digit of our result is 5. 
Result so far: 145.0
If we subtract 4535 from 4907, we get 372.
Append the next digit (9) from the dividend to 372 and continue with: 3729 / 907

Let's proceed to step 7:
907 goes into 3729 4 times with a remainder of 101.
Use 4 as the next digit of our solution. 
Result so far: 1454.0
If we subtract 3628 from 3729, we get 101.
Append the next digit (4) from the dividend to 101 and continue with: 1014 / 907

Advancing to step 8:
907 can be fit into 1014 1 times, resulting in a remainder of 107.
Put 1 as the next digit of the answer. 
Result so far: 14541.0
If we take 907 away from 1014, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 9:
If we divide 1070 by 907, we get 1 and a remainder of 163.
The next digit of our result is 1. 
Result so far: 14541.1
Subtracting 907 from 1070 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 10:
1630 divided by 907 is 1 with a remainder of 723.
Use 1 as the next digit of our solution. 
Result so far: 14541.11
Subtract 907 from 1630 to get 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

The final outcome is 14541.11, with a leftover of 0.723.
