Let's divide 12171515 by 125
Let's see how many times 125 fits into 12171515.

Advancing to step 1:
125 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
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 125

Advancing to step 2:
12 divided by 125 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 125

Step 3:
121 divided by 125 is 0 with a remainder of 121.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 121, we get 121.
Append the next digit (7) from the dividend to 121 and continue with: 1217 / 125

Step 4:
The number 125 fits into 1217 9 times, leaving a remainder of 92.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 1125 from 1217, we get 92.
Bring next digit (1) of the dividend behind the 92 and repeat the process: 921 / 125

Let's proceed to step 5:
125 can be fit into 921 7 times, resulting in a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 97.0
The remainder is 46 after subtracting 875 from 921.
Fetch the next digit (5) from the dividend, attach it to 46 and continue: 465 / 125

Moving on to step 6:
The number 125 fits into 465 3 times, leaving a remainder of 90.
Record the quotient 3 as the next digit in the result. 
Result so far: 973.0
If we subtract 375 from 465, we get 90.
Append the next digit (1) from the dividend to 90 and continue with: 901 / 125

Moving on to step 7:
The number 125 fits into 901 7 times, leaving a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 9737.0
If we subtract 875 from 901, we get 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 125

Advancing to step 8:
When dividing 265 by 125, we get 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 97372.0
Subtract 250 from 265 to get 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 9:
If we divide 150 by 125, we get 1 and a remainder of 25.
The next digit of our result is 1. 
Result so far: 97372.1
Subtracting 125 from 150 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
The number 125 fits into 250 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 97372.12
The remainder is 0 after subtracting 250 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
When dividing 0 by 125, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 97372.12
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
125 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 97372.12
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 97372.12, and the remainder is 0.0.
