Let's divide 221315 by 7
We're looking to find how many times 7 goes into 221315.

Moving on to step 1:
The number 7 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 7

Advancing to step 2:
When dividing 22 by 7, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 21 away from 22, we end up with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 7

Moving on to step 3:
The number 7 fits into 11 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 31.0
The remainder is 4 after subtracting 7 from 11.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 7

On to step 4:
If we divide 43 by 7, we get 6 and a remainder of 1.
The next digit of our result is 6. 
Result so far: 316.0
Subtract 42 from 43 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 7

Let's proceed to step 5:
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: 3161.0
Subtracting 7 from 11 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 7

Going ahead to step 6:
When dividing 45 by 7, we get 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 31616.0
Deduct 42 from 45 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.

Moving on to step 7:
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: 31616.4
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.

Advancing to step 8:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 31616.42
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 9:
60 divided by 7 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 31616.428
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.

Advancing to step 10:
7 goes into 40 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 31616.4285
If we subtract 35 from 40, we 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 11:
7 goes into 50 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 31616.42857
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.

Let's proceed to step 12:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 31616.428571
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.

Going ahead to step 13:
When dividing 30 by 7, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 31616.4285714
If we subtract 28 from 30, we get 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 14:
When dividing 20 by 7, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 31616.42857142
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.

After the division, we end up with 31616.42857142 and a remainder of 6e-09.
