213243 ÷ 7 
We're looking to find how many times 7 goes into 213243.

Let's proceed to step 1:
7 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 7

Moving on to step 2:
The number 7 fits into 21 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 21 from 21 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 7

Moving on to step 3:
7 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 7

On to step 4:
If we divide 32 by 7, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 304.0
If we subtract 28 from 32, we get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 7

Step 5:
44 divided by 7 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 3046.0
The remainder is 2 after subtracting 42 from 44.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 7

Let's proceed to step 6:
When dividing 23 by 7, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 30463.0
If we take 21 away from 23, 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.

Step 7:
20 divided by 7 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 30463.2
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 8:
If we divide 60 by 7, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 30463.28
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
If we divide 40 by 7, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 30463.285
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
50 divided by 7 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 30463.2857
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.

Moving on to step 11:
If we divide 10 by 7, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 30463.28571
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.

Going ahead to step 12:
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: 30463.285714
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.

Going ahead to step 13:
20 divided by 7 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 30463.2857142
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.

Step 14:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 30463.28571428
Subtract 56 from 60 to 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.

After the division, we end up with 30463.28571428 and a remainder of 4e-09.
