We look at the division of 855000 by 7 
We want to figure out the number of times 855000 can be divided by 7.

Advancing to step 1:
The number 7 fits into 8 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 7 away from 8, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 7

Moving on to step 2:
When dividing 15 by 7, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 14 from 15 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 7

On to step 3:
If we divide 15 by 7, we get 2 and a remainder of 1.
The next digit of our result is 2. 
Result so far: 122.0
Deduct 14 from 15 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 7

Step 4:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 1221.0
Subtracting 7 from 10 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 7

On to step 5:
If we divide 30 by 7, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 12214.0
If we subtract 28 from 30, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 7

Step 6:
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: 122142.0
The remainder is 6 after subtracting 14 from 20.
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 7:
7 goes into 60 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 122142.8
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.

Let's proceed to step 8:
7 goes into 40 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 122142.85
Subtracting 35 from 40 leaves us 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 9:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 122142.857
If we take 49 away from 50, we end up 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 10:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 122142.8571
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.

Step 11:
30 divided by 7 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 122142.85714
Subtract 28 from 30 to get 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:
20 divided by 7 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 122142.857142
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.

Step 13:
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: 122142.8571428
Subtract 56 from 60 to 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.

Let's proceed 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: 122142.85714285
Subtract 35 from 40 to 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.

After the division, we end up with 122142.85714285 and a remainder of 5e-09.
