We look at the division of 854880 by 7 
We're looking to find how many times 7 goes into 854880.

Step 1:
The number 7 fits into 8 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we take 7 away from 8, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 7

Moving on to step 2:
The number 7 fits into 15 2 times, leaving 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.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 7

Going ahead to step 3:
14 divided by 7 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 122.0
Subtract 14 from 14 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 7

Let's proceed to step 4:
8 divided by 7 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1221.0
Deduct 7 from 8 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 7

On to step 5:
When dividing 18 by 7, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 12212.0
Deduct 14 from 18 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 7

Advancing to step 6:
7 can be fit into 40 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 122125.0
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.

On to step 7:
50 divided by 7 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 122125.7
If we subtract 49 from 50, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
When dividing 10 by 7, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 122125.71
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.

Step 9:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 122125.714
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 10:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 122125.7142
If we subtract 14 from 20, 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.

On to step 11:
7 goes into 60 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 122125.71428
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.

Moving on to step 12:
If we divide 40 by 7, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 122125.714285
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 13:
7 goes into 50 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 122125.7142857
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.

Let's proceed to step 14:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 122125.71428571
Deduct 7 from 10 and we're left 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.

In conclusion, the division gives 122125.71428571 with a balance of 3e-09.
