We look at the division of 18117980 by 975 
Let's see how many times 975 fits into 18117980.

Going ahead to step 1:
975 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 975

On to step 2:
18 divided by 975 is 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 975

Advancing to step 3:
The number 975 fits into 181 0 times, leaving a remainder of 181.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 181 to get 181.
Include the next digit (1) from the dividend after 181, then repeat: 1811 / 975

Moving on to step 4:
The number 975 fits into 1811 1 times, leaving a remainder of 836.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 975 from 1811 leaves us with 836.
Bring next digit (7) of the dividend behind the 836 and repeat the process: 8367 / 975

On to step 5:
975 can be fit into 8367 8 times, resulting in a remainder of 567.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 567 after subtracting 7800 from 8367.
Bring next digit (9) of the dividend behind the 567 and repeat the process: 5679 / 975

Let's proceed to step 6:
5679 divided by 975 is 5 with a remainder of 804.
Use 5 as the next digit of our solution. 
Result so far: 185.0
If we take 4875 away from 5679, we end up with 804.
Fetch the next digit (8) from the dividend, attach it to 804 and continue: 8048 / 975

Going ahead to step 7:
8048 divided by 975 is 8 with a remainder of 248.
Write down 8 as next digit of the result. 
Result so far: 1858.0
Subtracting 7800 from 8048 leaves us with 248.
Bring next digit (0) of the dividend behind the 248 and repeat the process: 2480 / 975

Let's proceed to step 8:
When dividing 2480 by 975, we get 2 with a remainder of 530.
The number 2 becomes the next digit in our result. 
Result so far: 18582.0
Subtracting 1950 from 2480 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 9:
5300 divided by 975 is 5 with a remainder of 425.
Put 5 as the next digit of the answer. 
Result so far: 18582.5
Deduct 4875 from 5300 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

On to step 10:
975 goes into 4250 4 times with a remainder of 350.
Record the quotient 4 as the next digit in the result. 
Result so far: 18582.54
Deduct 3900 from 4250 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 11:
If we divide 3500 by 975, we get 3 and a remainder of 575.
The next digit of our result is 3. 
Result so far: 18582.543
The remainder is 575 after subtracting 2925 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Advancing to step 12:
975 can be fit into 5750 5 times, resulting in a remainder of 875.
Write down 5 as next digit of the result. 
Result so far: 18582.5435
Subtract 4875 from 5750 to get 875.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8750, and continue the process.

Let's proceed to step 13:
975 goes into 8750 8 times with a remainder of 950.
Use 8 as the next digit of our solution. 
Result so far: 18582.54358
Subtracting 7800 from 8750 leaves us with 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9500, and continue the process.

Moving on to step 14:
When dividing 9500 by 975, we get 9 with a remainder of 725.
Record the quotient 9 as the next digit in the result. 
Result so far: 18582.543589
If we subtract 8775 from 9500, we get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Advancing to step 15:
975 goes into 7250 7 times with a remainder of 425.
Write down 7 as next digit of the result. 
Result so far: 18582.5435897
Deduct 6825 from 7250 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 16:
975 goes into 4250 4 times with a remainder of 350.
Record the quotient 4 as the next digit in the result. 
Result so far: 18582.54358974
Deduct 3900 from 4250 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

In conclusion, the division gives 18582.54358974 with a balance of 3.5e-07.
