Let's divide 106515 by 87
Our goal is to divide 106515 by 87.

Let's proceed to step 1:
87 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 87

Let's proceed to step 2:
87 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 87

Let's proceed to step 3:
If we divide 106 by 87, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 87 away from 106, we end up with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 87

Moving on to step 4:
195 divided by 87 is 2 with a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 174 away from 195, we end up with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 87

Let's proceed to step 5:
The number 87 fits into 211 2 times, leaving a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
Deduct 174 from 211 and we're left with 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 87

Moving on to step 6:
87 can be fit into 375 4 times, resulting in a remainder of 27.
The next digit of our result is 4. 
Result so far: 1224.0
Subtracting 348 from 375 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
87 can be fit into 270 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 1224.3
Subtract 261 from 270 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
87 goes into 90 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1224.31
If we subtract 87 from 90, 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.

Step 9:
If we divide 30 by 87, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1224.31
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
300 divided by 87 is 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 1224.3103
The remainder is 39 after subtracting 261 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
87 goes into 390 4 times with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 1224.31034
Subtracting 348 from 390 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
420 divided by 87 is 4 with a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 1224.310344
The remainder is 72 after subtracting 348 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 1224.310344 with a remainder of 7.2e-06.
