We divide 852851 by 7
We want to figure out the number of times 852851 can be divided by 7.

Step 1:
If we divide 8 by 7, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 1 after subtracting 7 from 8.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 7

Going ahead to step 2:
15 divided by 7 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 1 after subtracting 14 from 15.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 7

On to step 3:
If we divide 12 by 7, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
If we take 7 away from 12, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 7

Advancing to step 4:
58 divided by 7 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1218.0
Deduct 56 from 58 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 7

Moving on to step 5:
If we divide 25 by 7, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 12183.0
The remainder is 4 after subtracting 21 from 25.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 7

Let's proceed to step 6:
If we divide 41 by 7, we get 5 and a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 121835.0
If we subtract 35 from 41, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to 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: 121835.8
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 8:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 121835.85
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 9:
7 goes into 50 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 121835.857
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 10:
7 can be fit into 10 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 121835.8571
The remainder is 3 after subtracting 7 from 10.
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:
When dividing 30 by 7, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 121835.85714
Subtracting 28 from 30 leaves us 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.

Going ahead to step 12:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 121835.857142
Subtract 14 from 20 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
When dividing 60 by 7, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 121835.8571428
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.

Going ahead to step 14:
If we divide 40 by 7, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 121835.85714285
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.

Our division results in 121835.85714285 with a remaining 5e-09.
