221583 divided by 7 
Our goal is to divide 221583 by 7.

Step 1:
7 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 7

On to step 2:
The number 7 fits into 22 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 21 from 22 to get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 7

Going ahead to step 3:
If we divide 11 by 7, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we subtract 7 from 11, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 7

Let's proceed to step 4:
45 divided by 7 is 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 316.0
The remainder is 3 after subtracting 42 from 45.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 7

Step 5:
7 can be fit into 38 5 times, resulting in a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 3165.0
Subtracting 35 from 38 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 7

Step 6:
7 can be fit into 33 4 times, resulting in a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 31654.0
If we take 28 away from 33, 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.

Let's proceed to step 7:
When dividing 50 by 7, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 31654.7
Subtracting 49 from 50 leaves us 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.

Going ahead to step 8:
10 divided by 7 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 31654.71
If we subtract 7 from 10, we get 3.
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 9:
30 divided by 7 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 31654.714
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
7 goes into 20 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 31654.7142
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.

Going ahead to step 11:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 31654.71428
If we take 56 away from 60, we end up 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.

Advancing to step 12:
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: 31654.714285
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.

On to step 13:
7 can be fit into 50 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 31654.7142857
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.

Let's proceed to step 14:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 31654.71428571
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.

The final outcome is 31654.71428571, with a leftover of 3e-09.
