861768 ÷ 7 
Let's see how many times 7 fits into 861768.

On to step 1:
The number 7 fits into 8 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 7 away from 8, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 7

Advancing to step 2:
If we divide 16 by 7, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 14 from 16 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 7

Advancing to step 3:
7 can be fit into 21 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 123.0
The remainder is 0 after subtracting 21 from 21.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 7

Advancing to step 4:
7 divided by 7 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1231.0
Subtract 7 from 7 to get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 7

On to step 5:
7 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 12310.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 7

Going ahead to step 6:
68 divided by 7 is 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 123109.0
Subtracting 63 from 68 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.

Going ahead to step 7:
7 goes into 50 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 123109.7
Subtracting 49 from 50 leaves us 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 8:
7 goes into 10 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 123109.71
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.

Going ahead to step 9:
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: 123109.714
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.

On to step 10:
7 goes into 20 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 123109.7142
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.

Let's proceed to step 11:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 123109.71428
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 12:
7 goes into 40 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 123109.714285
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.

Step 13:
When dividing 50 by 7, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 123109.7142857
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.

Advancing to step 14:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 123109.71428571
Subtracting 7 from 10 leaves us 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.

Our division results in 123109.71428571 with a remaining 3e-09.
