We're dividing 862990 by 7 
Let's see how many times 7 fits into 862990.

On to step 1:
7 goes into 8 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
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 2:
7 can be fit into 16 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 14 from 16 and we're left with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 7

Let's proceed to step 3:
When dividing 22 by 7, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 123.0
If we take 21 away from 22, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 7

On to step 4:
7 can be fit into 19 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 1232.0
Subtracting 14 from 19 leaves us with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 7

Advancing to step 5:
If we divide 59 by 7, we get 8 and a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 12328.0
Subtracting 56 from 59 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 7

Going ahead to step 6:
If we divide 30 by 7, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 123284.0
If we subtract 28 from 30, we 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.

Step 7:
If we divide 20 by 7, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 123284.2
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.

On to step 8:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 123284.28
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.

Step 9:
7 goes into 40 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 123284.285
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 10:
If we divide 50 by 7, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 123284.2857
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.

Advancing to step 11:
If we divide 10 by 7, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 123284.28571
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 12:
When dividing 30 by 7, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 123284.285714
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.

Moving on to step 13:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 123284.2857142
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.

On to step 14:
60 divided by 7 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 123284.28571428
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.

Our division results in 123284.28571428 with a remaining 4e-09.
