We look at the division of 77709942 by 75 
We want to figure out the number of times 77709942 can be divided by 75.

Let's proceed to step 1:
When dividing 7 by 75, we get 0 with 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.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 75

Going ahead to step 2:
75 goes into 77 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 75 from 77 and we're left with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 75

On to step 3:
When dividing 27 by 75, we get 0 with a remainder of 27.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 27, we get 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 75

Step 4:
75 goes into 270 3 times with a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
If we subtract 225 from 270, we get 45.
Fetch the next digit (9) from the dividend, attach it to 45 and continue: 459 / 75

Advancing to step 5:
75 goes into 459 6 times with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 1036.0
Subtracting 450 from 459 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 75

Step 6:
99 divided by 75 is 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 10361.0
If we take 75 away from 99, we end up with 24.
Append the next digit (4) from the dividend to 24 and continue with: 244 / 75

Moving on to step 7:
75 goes into 244 3 times with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 103613.0
Subtract 225 from 244 to get 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 75

Step 8:
75 goes into 192 2 times with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 1036132.0
Deduct 150 from 192 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
The number 75 fits into 420 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 1036132.5
If we take 375 away from 420, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
450 divided by 75 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 1036132.56
Subtract 450 from 450 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
75 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1036132.56
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
0 divided by 75 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1036132.56
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1036132.56, with a leftover of 0.0.
