We're dividing 867258 by 7 
We're looking to find how many times 7 goes into 867258.

Going ahead to step 1:
When dividing 8 by 7, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 7 away from 8, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 7

On to step 2:
If we divide 16 by 7, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 14 away from 16, we end up with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 7

On to step 3:
If we divide 27 by 7, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Deduct 21 from 27 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 7

Step 4:
7 can be fit into 62 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 1238.0
The remainder is 6 after subtracting 56 from 62.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 7

Advancing to step 5:
The number 7 fits into 65 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 12389.0
Subtracting 63 from 65 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 7

Going ahead to step 6:
The number 7 fits into 28 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 123894.0
If we take 28 away from 28, we end up 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.

Step 7:
7 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 123894.0
If we take 0 away from 0, we end up 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.

On to step 8:
If we divide 0 by 7, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 123894.0
Deduct 0 from 0 and we're left 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.

The final outcome is 123894.0, with a leftover of 0.0.
