We divide 129455 by 7
Our goal is to divide 129455 by 7.

On to step 1:
When dividing 1 by 7, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 7

Step 2:
7 can be fit into 12 1 times, resulting in a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 5 after subtracting 7 from 12.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 7

Advancing to step 3:
If we divide 59 by 7, we get 8 and a remainder of 3.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 56 from 59 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 7

On to step 4:
34 divided by 7 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 184.0
Deduct 28 from 34 and we're left with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 7

Moving on to step 5:
7 goes into 65 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 1849.0
If we subtract 63 from 65, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 7

Moving on to step 6:
If we divide 25 by 7, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 18493.0
The remainder is 4 after subtracting 21 from 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 18493.5
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
7 goes into 50 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 18493.57
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
7 goes into 10 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 18493.571
Subtract 7 from 10 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
7 goes into 30 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 18493.5714
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 18493.57142
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
If we divide 60 by 7, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 18493.571428
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
If we divide 40 by 7, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 18493.5714285
Subtract 35 from 40 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 18493.57142857
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 18493.57142857, with a leftover of 1e-09.
