Let's divide 210799 by 7
Our goal is to divide 210799 by 7.

On to step 1:
The number 7 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 7

Advancing to step 2:
7 can be fit into 21 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 21 away from 21, we end up with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 7

Let's proceed to step 3:
0 divided by 7 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 7

On to step 4:
When dividing 7 by 7, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 301.0
The remainder is 0 after subtracting 7 from 7.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 7

On to step 5:
9 divided by 7 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 3011.0
Subtracting 7 from 9 leaves us with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 7

Advancing to step 6:
If we divide 29 by 7, we get 4 and a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 30114.0
Subtract 28 from 29 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.

Advancing to step 7:
10 divided by 7 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 30114.1
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.

Let's proceed to step 8:
If we divide 30 by 7, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 30114.14
Deduct 28 from 30 and we're left 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 9:
If we divide 20 by 7, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 30114.142
Subtract 14 from 20 to 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 10:
When dividing 60 by 7, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 30114.1428
If we subtract 56 from 60, we get 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 11:
40 divided by 7 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 30114.14285
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.

Step 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 30114.142857
Deduct 49 from 50 and we're left 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.

On to step 13:
If we divide 10 by 7, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 30114.1428571
If we take 7 away from 10, we end up 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 14:
When dividing 30 by 7, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 30114.14285714
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.

The quotient of the division is 30114.14285714, and the remainder is 2e-09.
