27638703 ÷ 7 
We want to figure out the number of times 27638703 can be divided by 7.

Going ahead to step 1:
The number 7 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 7

On to step 2:
7 can be fit into 27 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 21 from 27, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 7

Advancing to step 3:
The number 7 fits into 66 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 39.0
The remainder is 3 after subtracting 63 from 66.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 7

Step 4:
If we divide 33 by 7, we get 4 and a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 394.0
Subtract 28 from 33 to get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 7

On to step 5:
58 divided by 7 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 3948.0
If we take 56 away from 58, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 7

On to step 6:
7 goes into 27 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 39483.0
Subtracting 21 from 27 leaves us with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 7

Let's proceed to step 7:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 394838.0
Subtract 56 from 60 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 7

Going ahead to step 8:
7 can be fit into 43 6 times, resulting in a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 3948386.0
If we subtract 42 from 43, 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.

Going ahead to step 9:
10 divided by 7 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 3948386.1
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.

Step 10:
7 can be fit into 30 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 3948386.14
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.

Advancing to step 11:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 3948386.142
If we take 14 away from 20, we end up 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.

Going ahead to step 12:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 3948386.1428
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.

Let's proceed to step 13:
7 goes into 40 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 3948386.14285
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:
If we divide 50 by 7, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 3948386.142857
Subtract 49 from 50 to 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.

Going ahead to step 15:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 3948386.1428571
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.

On to step 16:
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: 3948386.14285714
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.

The final result is 3948386.14285714 with a remainder of 2e-09.
