134878 divided by 7 
We're looking to find how many times 7 goes into 134878.

Going ahead to step 1:
1 divided by 7 is 0 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.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 7

Going ahead to step 2:
7 can be fit into 13 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 7 from 13 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 7

Advancing to step 3:
When dividing 64 by 7, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 63 from 64 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 7

Going ahead to step 4:
If we divide 18 by 7, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 192.0
The remainder is 4 after subtracting 14 from 18.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 7

On to step 5:
47 divided by 7 is 6 with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 1926.0
Deduct 42 from 47 and we're left with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 7

Advancing to step 6:
When dividing 58 by 7, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 19268.0
If we take 56 away from 58, 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.

On to step 7:
When dividing 20 by 7, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 19268.2
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.

Let's proceed to step 8:
When dividing 60 by 7, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 19268.28
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.

Let's proceed to step 9:
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: 19268.285
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.

Step 10:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 19268.2857
If we take 49 away from 50, we end up 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.

Moving on to step 11:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 19268.28571
If we subtract 7 from 10, we 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.

Moving on to step 12:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 19268.285714
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.

Step 13:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 19268.2857142
If we take 14 away from 20, we end up 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.

On to step 14:
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: 19268.28571428
If we take 56 away from 60, we end up 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.

Our division results in 19268.28571428 with a remaining 4e-09.
