7989959 divided by 75 
Our goal is to divide 7989959 by 75.

Let's proceed to step 1:
When dividing 7 by 75, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 75

On to step 2:
The number 75 fits into 79 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
If we take 75 away from 79, we end up with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 75

Let's proceed to step 3:
48 divided by 75 is 0 with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 48 after subtracting 0 from 48.
Grab the next digit (9) from the dividend, add it to 48, then carry on: 489 / 75

On to step 4:
When dividing 489 by 75, we get 6 with a remainder of 39.
The next digit of our result is 6. 
Result so far: 106.0
If we take 450 away from 489, we end up with 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 75

On to step 5:
When dividing 399 by 75, we get 5 with a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 1065.0
If we take 375 away from 399, we end up with 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 75

Going ahead to step 6:
245 divided by 75 is 3 with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 10653.0
Subtracting 225 from 245 leaves us with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 75

Going ahead to step 7:
The number 75 fits into 209 2 times, leaving a remainder of 59.
Put 2 as the next digit of the answer. 
Result so far: 106532.0
Deduct 150 from 209 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 8:
The number 75 fits into 590 7 times, leaving a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 106532.7
Subtracting 525 from 590 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 9:
75 goes into 650 8 times with a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 106532.78
The remainder is 50 after subtracting 600 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
If we divide 500 by 75, we get 6 and a remainder of 50.
The next digit of our result is 6. 
Result so far: 106532.786
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
When dividing 500 by 75, we get 6 with a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 106532.7866
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 106532.7866 and a remainder of 0.0005.
