We're dividing 172191 by 22 
Let's see how many times 22 fits into 172191.

Advancing to step 1:
22 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 22

Going ahead to step 2:
If we divide 17 by 22, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 22

Moving on to step 3:
The number 22 fits into 172 7 times, leaving a remainder of 18.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 154 from 172, we get 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 22

Advancing to step 4:
When dividing 181 by 22, we get 8 with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 78.0
Deduct 176 from 181 and we're left with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 22

Moving on to step 5:
22 can be fit into 59 2 times, resulting in a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 782.0
Subtract 44 from 59 to get 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 22

Let's proceed to step 6:
22 can be fit into 151 6 times, resulting in a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 7826.0
Subtracting 132 from 151 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
22 goes into 190 8 times with a remainder of 14.
The next digit of our result is 8. 
Result so far: 7826.8
Subtracting 176 from 190 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
22 goes into 140 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 7826.86
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
22 can be fit into 80 3 times, resulting in a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 7826.863
Subtracting 66 from 80 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
22 can be fit into 140 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 7826.8636
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
80 divided by 22 is 3 with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 7826.86363
If we take 66 away from 80, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
The number 22 fits into 140 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 7826.863636
If we take 132 away from 140, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
If we divide 80 by 22, we get 3 and a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 7826.8636363
If we take 66 away from 80, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
22 goes into 140 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 7826.86363636
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 7826.86363636 with a balance of 8e-09.
