216438 ÷ 7 
Our goal is to divide 216438 by 7.

Moving on to step 1:
The number 7 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 7

Step 2:
When dividing 21 by 7, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 21 from 21 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 7

Advancing to step 3:
If we divide 6 by 7, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 7

On to step 4:
64 divided by 7 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 309.0
Subtracting 63 from 64 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 7

Let's proceed to step 5:
7 goes into 13 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 3091.0
Subtracting 7 from 13 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 7

Let's proceed to step 6:
7 can be fit into 68 9 times, resulting in a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 30919.0
Subtracting 63 from 68 leaves us 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.

Moving on to step 7:
If we divide 50 by 7, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 30919.7
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.

Moving on to step 8:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 30919.71
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.

Advancing to step 9:
If we divide 30 by 7, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 30919.714
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.

On to step 10:
20 divided by 7 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 30919.7142
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.

Moving on to step 11:
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: 30919.71428
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.

Moving on to step 12:
If we divide 40 by 7, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 30919.714285
If we take 35 away from 40, we end up 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 13:
50 divided by 7 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 30919.7142857
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.

Step 14:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 30919.71428571
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 final outcome is 30919.71428571, with a leftover of 3e-09.
