Let's divide 187972 by 9
Our goal is to divide 187972 by 9.

Step 1:
If we divide 1 by 9, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 9

Step 2:
When dividing 18 by 9, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 18 away from 18, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 9

Going ahead to step 3:
9 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 9

On to step 4:
79 divided by 9 is 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 208.0
Subtract 72 from 79 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 9

On to step 5:
When dividing 77 by 9, we get 8 with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 2088.0
If we subtract 72 from 77, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 9

Going ahead to step 6:
If we divide 52 by 9, we get 5 and a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 20885.0
If we take 45 away from 52, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
70 divided by 9 is 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 20885.7
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
9 goes into 70 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 20885.77
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 20885.77 and a remainder of 0.007.
