We're dividing 129149 by 7 
We're looking to find how many times 7 goes into 129149.

Let's proceed to step 1:
If we divide 1 by 7, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 7

Let's proceed to step 2:
12 divided by 7 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 7 away from 12, we end up with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 7

Let's proceed to step 3:
59 divided by 7 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 56 from 59 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 7

Step 4:
When dividing 31 by 7, we get 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 184.0
If we take 28 away from 31, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 7

Moving on to step 5:
If we divide 34 by 7, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 1844.0
The remainder is 6 after subtracting 28 from 34.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 7

Let's proceed to step 6:
When dividing 69 by 7, we get 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 18449.0
If we subtract 63 from 69, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 18449.8
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 18449.85
If we subtract 35 from 40, we 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.

Advancing to step 9:
If we divide 50 by 7, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 18449.857
Deduct 49 from 50 and we're left 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.

On to step 10:
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: 18449.8571
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.

Let's proceed to step 11:
30 divided by 7 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 18449.85714
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 18449.857142
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.

Going ahead to step 13:
60 divided by 7 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 18449.8571428
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.

Going ahead to step 14:
If we divide 40 by 7, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 18449.85714285
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.

The final result is 18449.85714285 with a remainder of 5e-09.
