We look at the division of 18172543 by 975 
We want to figure out the number of times 18172543 can be divided by 975.

Moving on to step 1:
If we divide 1 by 975, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 975

Moving on to step 2:
18 divided by 975 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 975

Going ahead to step 3:
If we divide 181 by 975, we get 0 and a remainder of 181.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 181 leaves us with 181.
Fetch the next digit (7) from the dividend, attach it to 181 and continue: 1817 / 975

On to step 4:
The number 975 fits into 1817 1 times, leaving a remainder of 842.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 842 after subtracting 975 from 1817.
Fetch the next digit (2) from the dividend, attach it to 842 and continue: 8422 / 975

Moving on to step 5:
If we divide 8422 by 975, we get 8 and a remainder of 622.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 7800 from 8422, we get 622.
Include the next digit (5) from the dividend after 622, then repeat: 6225 / 975

Going ahead to step 6:
If we divide 6225 by 975, we get 6 and a remainder of 375.
The next digit of our result is 6. 
Result so far: 186.0
Subtract 5850 from 6225 to get 375.
Fetch the next digit (4) from the dividend, attach it to 375 and continue: 3754 / 975

On to step 7:
If we divide 3754 by 975, we get 3 and a remainder of 829.
The next digit of our result is 3. 
Result so far: 1863.0
Subtracting 2925 from 3754 leaves us with 829.
Fetch the next digit (3) from the dividend, attach it to 829 and continue: 8293 / 975

Moving on to step 8:
The number 975 fits into 8293 8 times, leaving a remainder of 493.
The number 8 becomes the next digit in our result. 
Result so far: 18638.0
Deduct 7800 from 8293 and we're left with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Advancing to step 9:
975 goes into 4930 5 times with a remainder of 55.
The next digit of our result is 5. 
Result so far: 18638.5
The remainder is 55 after subtracting 4875 from 4930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 10:
975 goes into 550 0 times with a remainder of 550.
Use 0 as the next digit of our solution. 
Result so far: 18638.5
Deduct 0 from 550 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 11:
The number 975 fits into 5500 5 times, leaving a remainder of 625.
Record the quotient 5 as the next digit in the result. 
Result so far: 18638.505
Subtracting 4875 from 5500 leaves us with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Going ahead to step 12:
The number 975 fits into 6250 6 times, leaving a remainder of 400.
Record the quotient 6 as the next digit in the result. 
Result so far: 18638.5056
Subtracting 5850 from 6250 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 13:
4000 divided by 975 is 4 with a remainder of 100.
Use 4 as the next digit of our solution. 
Result so far: 18638.50564
Subtracting 3900 from 4000 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 14:
If we divide 1000 by 975, we get 1 and a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 18638.505641
Subtract 975 from 1000 to get 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 15:
975 can be fit into 250 0 times, resulting in a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 18638.505641
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 16:
2500 divided by 975 is 2 with a remainder of 550.
Write down 2 as next digit of the result. 
Result so far: 18638.50564102
If we take 1950 away from 2500, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

After the division, we end up with 18638.50564102 and a remainder of 5.5e-07.
