77957 divided by 75 
We're looking to find how many times 75 goes into 77957.

Step 1:
If we divide 7 by 75, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 75

Going ahead to step 2:
If we divide 77 by 75, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 75 from 77 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 75

Advancing to step 3:
When dividing 29 by 75, we get 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 29 after subtracting 0 from 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 75

Advancing to step 4:
75 can be fit into 295 3 times, resulting in a remainder of 70.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
If we take 225 away from 295, we end up with 70.
Bring next digit (7) of the dividend behind the 70 and repeat the process: 707 / 75

On to step 5:
When dividing 707 by 75, we get 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 1039.0
Deduct 675 from 707 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 6:
75 can be fit into 320 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 1039.4
Subtracting 300 from 320 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
The number 75 fits into 200 2 times, leaving a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 1039.42
If we subtract 150 from 200, we 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.

Let's proceed to step 8:
If we divide 500 by 75, we get 6 and a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 1039.426
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.

Let's proceed to step 9:
When dividing 500 by 75, we get 6 with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 1039.4266
If we take 450 away from 500, we end up 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.

The final outcome is 1039.4266, with a leftover of 0.0005.
