We're dividing 109017 by 87 
We want to figure out the number of times 109017 can be divided by 87.

Advancing to step 1:
87 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 87

Step 2:
If we divide 10 by 87, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 87

Let's proceed to step 3:
87 goes into 109 1 times with a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 87 from 109 to get 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 87

On to step 4:
The number 87 fits into 220 2 times, leaving a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 174 from 220 to get 46.
Bring next digit (1) of the dividend behind the 46 and repeat the process: 461 / 87

Advancing to step 5:
461 divided by 87 is 5 with a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtracting 435 from 461 leaves us with 26.
Bring next digit (7) of the dividend behind the 26 and repeat the process: 267 / 87

Going ahead to step 6:
267 divided by 87 is 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 1253.0
Subtracting 261 from 267 leaves us 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.

On to step 7:
If we divide 60 by 87, we get 0 and a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 1253.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
When dividing 600 by 87, we get 6 with a remainder of 78.
Record the quotient 6 as the next digit in the result. 
Result so far: 1253.06
Subtract 522 from 600 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 9:
87 goes into 780 8 times with a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 1253.068
Subtracting 696 from 780 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 10:
840 divided by 87 is 9 with a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 1253.0689
The remainder is 57 after subtracting 783 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 11:
87 can be fit into 570 6 times, resulting in a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 1253.06896
If we subtract 522 from 570, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
87 goes into 480 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 1253.068965
Subtracting 435 from 480 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 13:
When dividing 450 by 87, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1253.0689655
Subtracting 435 from 450 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.

In conclusion, the division gives 1253.0689655 with a balance of 1.5e-07.
