99253316 ÷ 860 
We want to figure out the number of times 99253316 can be divided by 860.

Moving on to step 1:
860 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 860

On to step 2:
The number 860 fits into 99 0 times, leaving a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Grab the next digit (2) from the dividend, add it to 99, then carry on: 992 / 860

Step 3:
992 divided by 860 is 1 with a remainder of 132.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 132 after subtracting 860 from 992.
Include the next digit (5) from the dividend after 132, then repeat: 1325 / 860

Going ahead to step 4:
1325 divided by 860 is 1 with a remainder of 465.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 465 after subtracting 860 from 1325.
Take the next digit (3) from the dividend and append it to 465, then repeat: 4653 / 860

Step 5:
If we divide 4653 by 860, we get 5 and a remainder of 353.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Subtracting 4300 from 4653 leaves us with 353.
Bring next digit (3) of the dividend behind the 353 and repeat the process: 3533 / 860

Step 6:
The number 860 fits into 3533 4 times, leaving a remainder of 93.
The number 4 becomes the next digit in our result. 
Result so far: 1154.0
If we subtract 3440 from 3533, we get 93.
Include the next digit (1) from the dividend after 93, then repeat: 931 / 860

On to step 7:
860 goes into 931 1 times with a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 11541.0
Subtract 860 from 931 to get 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 860

On to step 8:
If we divide 716 by 860, we get 0 and a remainder of 716.
Write down 0 as next digit of the result. 
Result so far: 115410.0
Subtract 0 from 716 to get 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Advancing to step 9:
The number 860 fits into 7160 8 times, leaving a remainder of 280.
Use 8 as the next digit of our solution. 
Result so far: 115410.8
Deduct 6880 from 7160 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 10:
860 can be fit into 2800 3 times, resulting in a remainder of 220.
The number 3 becomes the next digit in our result. 
Result so far: 115410.83
Deduct 2580 from 2800 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 11:
860 can be fit into 2200 2 times, resulting in a remainder of 480.
Put 2 as the next digit of the answer. 
Result so far: 115410.832
If we take 1720 away from 2200, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 12:
The number 860 fits into 4800 5 times, leaving a remainder of 500.
Put 5 as the next digit of the answer. 
Result so far: 115410.8325
Subtract 4300 from 4800 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 13:
860 can be fit into 5000 5 times, resulting in a remainder of 700.
Write down 5 as next digit of the result. 
Result so far: 115410.83255
Deduct 4300 from 5000 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

After the division, we end up with 115410.83255 and a remainder of 0.0007.
