We look at the division of 86958 by 7 
Let's see how many times 7 fits into 86958.

Advancing to step 1:
The number 7 fits into 8 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 7 from 8 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 7

Going ahead to step 2:
7 can be fit into 16 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 14 from 16 to get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 7

On to step 3:
29 divided by 7 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 124.0
If we take 28 away from 29, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 7

Moving on to step 4:
15 divided by 7 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 1242.0
Subtracting 14 from 15 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 7

Going ahead to step 5:
If we divide 18 by 7, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 12422.0
The remainder is 4 after subtracting 14 from 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 6:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 12422.5
If we take 35 away from 40, we end up with 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 7:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 12422.57
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.

Let's proceed to step 8:
If we divide 10 by 7, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 12422.571
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.

Going ahead to step 9:
7 goes into 30 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 12422.5714
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 10:
7 goes into 20 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 12422.57142
Subtracting 14 from 20 leaves us 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.

Moving on to step 11:
When dividing 60 by 7, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 12422.571428
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.

Let's proceed to step 12:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 12422.5714285
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.

On to step 13:
7 goes into 50 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 12422.57142857
The remainder is 1 after subtracting 49 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 12422.57142857 with a remaining 1e-09.
