Let's divide 79909 by 75
We want to figure out the number of times 79909 can be divided by 75.

Advancing to step 1:
The number 75 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 75

Going ahead to step 2:
79 divided by 75 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 4 after subtracting 75 from 79.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 75

Let's proceed to step 3:
75 can be fit into 49 0 times, resulting in a remainder of 49.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 49 and we're left with 49.
Include the next digit (0) from the dividend after 49, then repeat: 490 / 75

On to step 4:
The number 75 fits into 490 6 times, leaving a remainder of 40.
The next digit of our result is 6. 
Result so far: 106.0
Subtract 450 from 490 to get 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 75

Going ahead to step 5:
409 divided by 75 is 5 with a remainder of 34.
Record the quotient 5 as the next digit in the result. 
Result so far: 1065.0
Subtract 375 from 409 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 6:
340 divided by 75 is 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 1065.4
If we subtract 300 from 340, we 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.

Let's proceed to step 7:
75 goes into 400 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 1065.45
If we take 375 away from 400, 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.

On to step 8:
When dividing 250 by 75, we get 3 with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 1065.453
If we subtract 225 from 250, 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.

Going ahead to step 9:
75 goes into 250 3 times with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 1065.4533
Subtract 225 from 250 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.

The final result is 1065.4533 with a remainder of 0.00025.
