Let's divide 66787897 by 7
Let's see how many times 7 fits into 66787897.

Advancing to step 1:
The number 7 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 7

Step 2:
The number 7 fits into 66 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 63 from 66 leaves us with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 7

Advancing to step 3:
7 goes into 37 5 times with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 95.0
If we take 35 away from 37, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 7

Advancing to step 4:
7 can be fit into 28 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 954.0
The remainder is 0 after subtracting 28 from 28.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 7

Moving on to step 5:
7 divided by 7 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 9541.0
If we subtract 7 from 7, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 7

Let's proceed to step 6:
8 divided by 7 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 95411.0
If we take 7 away from 8, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 7

Moving on to step 7:
The number 7 fits into 19 2 times, leaving a remainder of 5.
The next digit of our result is 2. 
Result so far: 954112.0
The remainder is 5 after subtracting 14 from 19.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 7

Advancing to step 8:
7 goes into 57 8 times with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 9541128.0
The remainder is 1 after subtracting 56 from 57.
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 9:
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: 9541128.1
Subtract 7 from 10 to get 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 10:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 9541128.14
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.

Step 11:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 9541128.142
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.

Moving on to step 12:
When dividing 60 by 7, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 9541128.1428
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 13:
40 divided by 7 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 9541128.14285
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.

On to step 14:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 9541128.142857
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.

Advancing to step 15:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 9541128.1428571
If we subtract 7 from 10, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 16:
If we divide 30 by 7, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 9541128.14285714
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.

After the division, we end up with 9541128.14285714 and a remainder of 2e-09.
