We're dividing 172217 by 87 
We're looking to find how many times 87 goes into 172217.

On to step 1:
87 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 87

Advancing to step 2:
17 divided by 87 is 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 87

Let's proceed to step 3:
172 divided by 87 is 1 with a remainder of 85.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 87 from 172 and we're left with 85.
Take the next digit (2) from the dividend and append it to 85, then repeat: 852 / 87

Let's proceed to step 4:
When dividing 852 by 87, we get 9 with a remainder of 69.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 783 from 852 and we're left with 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 87

Step 5:
87 goes into 691 7 times with a remainder of 82.
Use 7 as the next digit of our solution. 
Result so far: 197.0
The remainder is 82 after subtracting 609 from 691.
Grab the next digit (7) from the dividend, add it to 82, then carry on: 827 / 87

Going ahead to step 6:
87 can be fit into 827 9 times, resulting in a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 1979.0
Deduct 783 from 827 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 7:
440 divided by 87 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1979.5
Subtract 435 from 440 to 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.

On to step 8:
50 divided by 87 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 1979.5
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
If we divide 500 by 87, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 1979.505
Subtract 435 from 500 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 10:
87 goes into 650 7 times with a remainder of 41.
The next digit of our result is 7. 
Result so far: 1979.5057
Subtract 609 from 650 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 11:
87 can be fit into 410 4 times, resulting in a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 1979.50574
If we take 348 away from 410, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
The number 87 fits into 620 7 times, leaving a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 1979.505747
Subtracting 609 from 620 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 13:
87 goes into 110 1 times with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1979.5057471
Deduct 87 from 110 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 14:
230 divided by 87 is 2 with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 1979.50574712
Subtracting 174 from 230 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 1979.50574712, and the remainder is 5.6e-08.
