We look at the division of 17125869 by 108 
Our goal is to divide 17125869 by 108.

Step 1:
The number 108 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 108

Advancing to step 2:
When dividing 17 by 108, we get 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 108

Let's proceed to step 3:
When dividing 171 by 108, we get 1 with a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 108 from 171, we get 63.
Fetch the next digit (2) from the dividend, attach it to 63 and continue: 632 / 108

Moving on to step 4:
When dividing 632 by 108, we get 5 with a remainder of 92.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 540 from 632 leaves us with 92.
Bring next digit (5) of the dividend behind the 92 and repeat the process: 925 / 108

Going ahead to step 5:
If we divide 925 by 108, we get 8 and a remainder of 61.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
Deduct 864 from 925 and we're left with 61.
Append the next digit (8) from the dividend to 61 and continue with: 618 / 108

Let's proceed to step 6:
When dividing 618 by 108, we get 5 with a remainder of 78.
Put 5 as the next digit of the answer. 
Result so far: 1585.0
If we take 540 away from 618, we end up with 78.
Append the next digit (6) from the dividend to 78 and continue with: 786 / 108

Going ahead to step 7:
108 goes into 786 7 times with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 15857.0
Subtract 756 from 786 to get 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 108

Advancing to step 8:
When dividing 309 by 108, we get 2 with a remainder of 93.
The next digit of our result is 2. 
Result so far: 158572.0
If we take 216 away from 309, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 9:
108 can be fit into 930 8 times, resulting in a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 158572.8
Deduct 864 from 930 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 10:
If we divide 660 by 108, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 158572.86
Subtracting 648 from 660 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
120 divided by 108 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 158572.861
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
108 goes into 120 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 158572.8611
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 158572.8611 and a remainder of 0.00012.
