136878 ÷ 1 
We're looking to find how many times 1 goes into 136878.

Let's proceed to step 1:
If we divide 1 by 1, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 1 from 1 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Let's proceed to step 2:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 3 from 3, we get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Advancing to step 3:
If we divide 6 by 1, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 136.0
Deduct 6 from 6 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Advancing to step 4:
8 divided by 1 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 1368.0
Subtract 8 from 8 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

Advancing to step 5:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 13687.0
Subtracting 7 from 7 leaves us with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Advancing to step 6:
When dividing 8 by 1, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 136878.0
Subtracting 8 from 8 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 136878.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 136878.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 136878.0, with a leftover of 0.0.
