We look at the division of 81315985 by 828 
We want to figure out the number of times 81315985 can be divided by 828.

Moving on to step 1:
If we divide 8 by 828, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 828

Advancing to step 2:
828 can be fit into 81 0 times, resulting in a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (3) from the dividend and append it to 81, then repeat: 813 / 828

Moving on to step 3:
828 can be fit into 813 0 times, resulting in a remainder of 813.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 813, we get 813.
Bring next digit (1) of the dividend behind the 813 and repeat the process: 8131 / 828

Step 4:
8131 divided by 828 is 9 with a remainder of 679.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 7452 from 8131, we get 679.
Take the next digit (5) from the dividend and append it to 679, then repeat: 6795 / 828

Step 5:
The number 828 fits into 6795 8 times, leaving a remainder of 171.
The next digit of our result is 8. 
Result so far: 98.0
The remainder is 171 after subtracting 6624 from 6795.
Bring next digit (9) of the dividend behind the 171 and repeat the process: 1719 / 828

Step 6:
828 can be fit into 1719 2 times, resulting in a remainder of 63.
Write down 2 as next digit of the result. 
Result so far: 982.0
Subtracting 1656 from 1719 leaves us with 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 828

Let's proceed to step 7:
When dividing 638 by 828, we get 0 with a remainder of 638.
Write down 0 as next digit of the result. 
Result so far: 9820.0
If we subtract 0 from 638, we get 638.
Take the next digit (5) from the dividend and append it to 638, then repeat: 6385 / 828

Advancing to step 8:
828 can be fit into 6385 7 times, resulting in a remainder of 589.
Write down 7 as next digit of the result. 
Result so far: 98207.0
If we take 5796 away from 6385, we end up with 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Advancing to step 9:
828 goes into 5890 7 times with a remainder of 94.
The number 7 becomes the next digit in our result. 
Result so far: 98207.7
If we take 5796 away from 5890, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 10:
When dividing 940 by 828, we get 1 with a remainder of 112.
The next digit of our result is 1. 
Result so far: 98207.71
Subtract 828 from 940 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 11:
1120 divided by 828 is 1 with a remainder of 292.
Put 1 as the next digit of the answer. 
Result so far: 98207.711
Subtract 828 from 1120 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

After the division, we end up with 98207.711 and a remainder of 0.0292.
