99952581 ÷ 778 
We want to figure out the number of times 99952581 can be divided by 778.

Going ahead to step 1:
If we divide 9 by 778, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 778

Moving on to step 2:
99 divided by 778 is 0 with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Bring next digit (9) of the dividend behind the 99 and repeat the process: 999 / 778

Step 3:
778 can be fit into 999 1 times, resulting in a remainder of 221.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 778 from 999 leaves us with 221.
Fetch the next digit (5) from the dividend, attach it to 221 and continue: 2215 / 778

Let's proceed to step 4:
778 can be fit into 2215 2 times, resulting in a remainder of 659.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 1556 away from 2215, we end up with 659.
Include the next digit (2) from the dividend after 659, then repeat: 6592 / 778

Going ahead to step 5:
If we divide 6592 by 778, we get 8 and a remainder of 368.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Subtracting 6224 from 6592 leaves us with 368.
Fetch the next digit (5) from the dividend, attach it to 368 and continue: 3685 / 778

Advancing to step 6:
If we divide 3685 by 778, we get 4 and a remainder of 573.
The number 4 becomes the next digit in our result. 
Result so far: 1284.0
If we take 3112 away from 3685, we end up with 573.
Include the next digit (8) from the dividend after 573, then repeat: 5738 / 778

On to step 7:
778 goes into 5738 7 times with a remainder of 292.
Put 7 as the next digit of the answer. 
Result so far: 12847.0
Subtracting 5446 from 5738 leaves us with 292.
Bring next digit (1) of the dividend behind the 292 and repeat the process: 2921 / 778

On to step 8:
When dividing 2921 by 778, we get 3 with a remainder of 587.
Write down 3 as next digit of the result. 
Result so far: 128473.0
Deduct 2334 from 2921 and we're left with 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Advancing to step 9:
5870 divided by 778 is 7 with a remainder of 424.
Use 7 as the next digit of our solution. 
Result so far: 128473.7
Subtract 5446 from 5870 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 10:
If we divide 4240 by 778, we get 5 and a remainder of 350.
The next digit of our result is 5. 
Result so far: 128473.75
If we subtract 3890 from 4240, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 11:
When dividing 3500 by 778, we get 4 with a remainder of 388.
Write down 4 as next digit of the result. 
Result so far: 128473.754
Subtracting 3112 from 3500 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 12:
778 goes into 3880 4 times with a remainder of 768.
Use 4 as the next digit of our solution. 
Result so far: 128473.7544
If we subtract 3112 from 3880, we get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

The final outcome is 128473.7544, with a leftover of 0.00768.
