We look at the division of 848686 by 7 
We want to divide 848686 by 7.

On to step 1:
7 can be fit into 8 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 7 from 8.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 7

Advancing to step 2:
If we divide 14 by 7, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 14 from 14 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 7

Let's proceed to step 3:
7 goes into 8 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
Subtract 7 from 8 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 7

Step 4:
16 divided by 7 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 1212.0
Deduct 14 from 16 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 7

Let's proceed to step 5:
When dividing 28 by 7, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 12124.0
The remainder is 0 after subtracting 28 from 28.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 7

Step 6:
6 divided by 7 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 121240.0
If we take 0 away from 6, 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.

Step 7:
7 goes into 60 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 121240.8
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.

On to step 8:
If we divide 40 by 7, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 121240.85
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.

Let's proceed to step 9:
When dividing 50 by 7, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 121240.857
Subtracting 49 from 50 leaves us 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.

Advancing 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: 121240.8571
If we take 7 away from 10, we end up with 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:
7 goes into 30 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 121240.85714
Deduct 28 from 30 and we're left 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 12:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 121240.857142
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 13:
7 goes into 60 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 121240.8571428
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.

On to step 14:
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: 121240.85714285
Deduct 35 from 40 and we're left 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.

The final result is 121240.85714285 with a remainder of 5e-09.
