3 divided by 7 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 3, we end up with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 7

Let's proceed to step 3:
36 divided by 7 is 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
Deduct 35 from 36 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 7

On to step 4:
7 can be fit into 11 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1051.0
Deduct 7 from 11 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 7

Advancing to step 5:
When dividing 42 by 7, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 10516.0
Subtract 42 from 42 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 7

Let's proceed to step 6:
When dividing 9 by 7, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 105161.0
Deduct 7 from 9 and we're left with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 7

Going ahead to step 7:
7 can be fit into 22 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 1051613.0
If we subtract 21 from 22, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 7

Let's proceed to step 8:
If we divide 19 by 7, we get 2 and a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 10516132.0
Deduct 14 from 19 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.

Step 9:
When dividing 50 by 7, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 10516132.7
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 10:
10 divided by 7 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 10516132.71
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.

Let's proceed to step 11:
When dividing 30 by 7, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 10516132.714
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 12:
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: 10516132.7142
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 13:
When dividing 60 by 7, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 10516132.71428
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.

Let's proceed to step 14:
7 can be fit into 40 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 10516132.714285
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.

Moving on to step 15:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 10516132.7142857
The remainder is 1 after subtracting 49 from 50.
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 16:
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: 10516132.71428571
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.

The quotient of the division is 10516132.71428571, and the remainder is 3e-09.
