We're dividing 215131 by 22 
We want to figure out the number of times 215131 can be divided by 22.

Advancing to step 1:
If we divide 2 by 22, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 22

Step 2:
21 divided by 22 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 22

Moving on to step 3:
22 can be fit into 215 9 times, resulting in a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 198 from 215 and we're left with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 22

Advancing to step 4:
22 goes into 171 7 times with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
The remainder is 17 after subtracting 154 from 171.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 22

Moving on to step 5:
173 divided by 22 is 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 977.0
If we take 154 away from 173, we end up with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 22

Going ahead to step 6:
22 can be fit into 191 8 times, resulting in a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 9778.0
Subtracting 176 from 191 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
When dividing 150 by 22, we get 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 9778.6
Deduct 132 from 150 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
If we divide 180 by 22, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 9778.68
If we subtract 176 from 180, 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 9:
When dividing 40 by 22, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 9778.681
If we take 22 away from 40, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
22 goes into 180 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 9778.6818
Deduct 176 from 180 and we're left 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.

Moving on to step 11:
If we divide 40 by 22, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 9778.68181
Subtracting 22 from 40 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 12:
180 divided by 22 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 9778.681818
The remainder is 4 after subtracting 176 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
When dividing 40 by 22, we get 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 9778.6818181
Deduct 22 from 40 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
180 divided by 22 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 9778.68181818
Deduct 176 from 180 and we're left 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.

The final result is 9778.68181818 with a remainder of 4e-09.
