We look at the division of 81992540 by 858 
We want to figure out the number of times 81992540 can be divided by 858.

Step 1:
8 divided by 858 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 858

Moving on to step 2:
When dividing 81 by 858, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 858

Let's proceed to step 3:
If we divide 819 by 858, we get 0 and a remainder of 819.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 819 leaves us with 819.
Append the next digit (9) from the dividend to 819 and continue with: 8199 / 858

Moving on to step 4:
858 goes into 8199 9 times with a remainder of 477.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 7722 from 8199 leaves us with 477.
Take the next digit (2) from the dividend and append it to 477, then repeat: 4772 / 858

Going ahead to step 5:
858 goes into 4772 5 times with a remainder of 482.
Put 5 as the next digit of the answer. 
Result so far: 95.0
Subtract 4290 from 4772 to get 482.
Include the next digit (5) from the dividend after 482, then repeat: 4825 / 858

Moving on to step 6:
The number 858 fits into 4825 5 times, leaving a remainder of 535.
Record the quotient 5 as the next digit in the result. 
Result so far: 955.0
The remainder is 535 after subtracting 4290 from 4825.
Grab the next digit (4) from the dividend, add it to 535, then carry on: 5354 / 858

On to step 7:
If we divide 5354 by 858, we get 6 and a remainder of 206.
Put 6 as the next digit of the answer. 
Result so far: 9556.0
Subtracting 5148 from 5354 leaves us with 206.
Take the next digit (0) from the dividend and append it to 206, then repeat: 2060 / 858

Moving on to step 8:
If we divide 2060 by 858, we get 2 and a remainder of 344.
Use 2 as the next digit of our solution. 
Result so far: 95562.0
The remainder is 344 after subtracting 1716 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 9:
858 goes into 3440 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 95562.4
If we take 3432 away from 3440, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
The number 858 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 95562.4
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
858 can be fit into 800 0 times, resulting in a remainder of 800.
Write down 0 as next digit of the result. 
Result so far: 95562.4
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

After the division, we end up with 95562.4 and a remainder of 0.08.
