991690 ÷ 75 
Our goal is to divide 991690 by 75.

Moving on to step 1:
75 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 75

On to step 2:
75 goes into 99 1 times with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 75 from 99 and we're left with 24.
Bring next digit (1) of the dividend behind the 24 and repeat the process: 241 / 75

Step 3:
When dividing 241 by 75, we get 3 with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 225 from 241, we get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 75

Let's proceed to step 4:
166 divided by 75 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 132.0
Subtract 150 from 166 to get 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 75

Advancing to step 5:
169 divided by 75 is 2 with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 1322.0
If we take 150 away from 169, we end up with 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 75

Going ahead to step 6:
When dividing 190 by 75, we get 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 13222.0
Subtract 150 from 190 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
The number 75 fits into 400 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 13222.5
If we subtract 375 from 400, we 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.

Step 8:
75 goes into 250 3 times with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 13222.53
If we take 225 away from 250, we end up 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.

Moving on to step 9:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 13222.533
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 13222.533 and a remainder of 0.0025.
