77309453 ÷ 955 
We're looking to find how many times 955 goes into 77309453.

Moving on to step 1:
The number 955 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 955

Advancing to step 2:
When dividing 77 by 955, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 955

Going ahead to step 3:
The number 955 fits into 773 0 times, leaving a remainder of 773.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 773 after subtracting 0 from 773.
Append the next digit (0) from the dividend to 773 and continue with: 7730 / 955

Going ahead to step 4:
7730 divided by 955 is 8 with a remainder of 90.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 7640 from 7730 and we're left with 90.
Fetch the next digit (9) from the dividend, attach it to 90 and continue: 909 / 955

Step 5:
The number 955 fits into 909 0 times, leaving a remainder of 909.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtracting 0 from 909 leaves us with 909.
Append the next digit (4) from the dividend to 909 and continue with: 9094 / 955

On to step 6:
9094 divided by 955 is 9 with a remainder of 499.
Use 9 as the next digit of our solution. 
Result so far: 809.0
If we take 8595 away from 9094, we end up with 499.
Fetch the next digit (5) from the dividend, attach it to 499 and continue: 4995 / 955

Let's proceed to step 7:
If we divide 4995 by 955, we get 5 and a remainder of 220.
Write down 5 as next digit of the result. 
Result so far: 8095.0
Deduct 4775 from 4995 and we're left with 220.
Take the next digit (3) from the dividend and append it to 220, then repeat: 2203 / 955

On to step 8:
955 can be fit into 2203 2 times, resulting in a remainder of 293.
Put 2 as the next digit of the answer. 
Result so far: 80952.0
Deduct 1910 from 2203 and we're left with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Advancing to step 9:
The number 955 fits into 2930 3 times, leaving a remainder of 65.
Put 3 as the next digit of the answer. 
Result so far: 80952.3
If we take 2865 away from 2930, we end up 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.

Advancing to step 10:
955 can be fit into 650 0 times, resulting in a remainder of 650.
The next digit of our result is 0. 
Result so far: 80952.3
If we subtract 0 from 650, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Going ahead to step 11:
955 can be fit into 6500 6 times, resulting in a remainder of 770.
Put 6 as the next digit of the answer. 
Result so far: 80952.306
Deduct 5730 from 6500 and we're left with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

On to step 12:
7700 divided by 955 is 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 80952.3068
If we take 7640 away from 7700, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
600 divided by 955 is 0 with a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 80952.3068
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 14:
When dividing 6000 by 955, we get 6 with a remainder of 270.
Write down 6 as next digit of the result. 
Result so far: 80952.306806
If we take 5730 away from 6000, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 15:
The number 955 fits into 2700 2 times, leaving a remainder of 790.
Write down 2 as next digit of the result. 
Result so far: 80952.3068062
If we take 1910 away from 2700, we end up with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Moving on to step 16:
955 goes into 7900 8 times with a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 80952.30680628
Subtracting 7640 from 7900 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 80952.30680628, with a leftover of 2.6e-07.
