We look at the division of 168506 by 7 
Let's see how many times 7 fits into 168506.

On to step 1:
The number 7 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 7

Going ahead to step 2:
The number 7 fits into 16 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 2 after subtracting 14 from 16.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 7

Going ahead to step 3:
If we divide 28 by 7, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtracting 28 from 28 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 7

Going ahead to step 4:
7 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 240.0
Subtract 0 from 5 to get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 7

On to step 5:
50 divided by 7 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 2407.0
Subtract 49 from 50 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 7

Let's proceed to step 6:
16 divided by 7 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 24072.0
If we take 14 away from 16, 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.

Let's proceed to step 7:
If we divide 20 by 7, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 24072.2
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.

Moving on to step 8:
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: 24072.28
Subtracting 56 from 60 leaves us 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 9:
40 divided by 7 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 24072.285
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.

On to step 10:
7 goes into 50 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 24072.2857
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.

On to step 11:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 24072.28571
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.

Step 12:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 24072.285714
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.

Let's proceed to step 13:
7 goes into 20 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 24072.2857142
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 14:
If we divide 60 by 7, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 24072.28571428
Deduct 56 from 60 and we're left 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 24072.28571428 with a remaining 4e-09.
