We look at the division of 84257540 by 815 
We want to figure out the number of times 84257540 can be divided by 815.

Moving on to step 1:
8 divided by 815 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 815

On to step 2:
84 divided by 815 is 0 with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Include the next digit (2) from the dividend after 84, then repeat: 842 / 815

Advancing to step 3:
842 divided by 815 is 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 815 from 842 leaves us with 27.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 815

Going ahead to step 4:
The number 815 fits into 275 0 times, leaving a remainder of 275.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 275 and we're left with 275.
Fetch the next digit (7) from the dividend, attach it to 275 and continue: 2757 / 815

Going ahead to step 5:
815 can be fit into 2757 3 times, resulting in a remainder of 312.
Write down 3 as next digit of the result. 
Result so far: 103.0
If we take 2445 away from 2757, we end up with 312.
Bring next digit (5) of the dividend behind the 312 and repeat the process: 3125 / 815

Step 6:
If we divide 3125 by 815, we get 3 and a remainder of 680.
Use 3 as the next digit of our solution. 
Result so far: 1033.0
Subtract 2445 from 3125 to get 680.
Append the next digit (4) from the dividend to 680 and continue with: 6804 / 815

Step 7:
The number 815 fits into 6804 8 times, leaving a remainder of 284.
Write down 8 as next digit of the result. 
Result so far: 10338.0
Deduct 6520 from 6804 and we're left with 284.
Fetch the next digit (0) from the dividend, attach it to 284 and continue: 2840 / 815

Going ahead to step 8:
If we divide 2840 by 815, we get 3 and a remainder of 395.
Use 3 as the next digit of our solution. 
Result so far: 103383.0
The remainder is 395 after subtracting 2445 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Step 9:
When dividing 3950 by 815, we get 4 with a remainder of 690.
Put 4 as the next digit of the answer. 
Result so far: 103383.4
Subtracting 3260 from 3950 leaves us with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Step 10:
The number 815 fits into 6900 8 times, leaving a remainder of 380.
Put 8 as the next digit of the answer. 
Result so far: 103383.48
The remainder is 380 after subtracting 6520 from 6900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 11:
When dividing 3800 by 815, we get 4 with a remainder of 540.
Record the quotient 4 as the next digit in the result. 
Result so far: 103383.484
If we subtract 3260 from 3800, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 12:
815 goes into 5400 6 times with a remainder of 510.
The next digit of our result is 6. 
Result so far: 103383.4846
If we take 4890 away from 5400, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 13:
5100 divided by 815 is 6 with a remainder of 210.
Use 6 as the next digit of our solution. 
Result so far: 103383.48466
The remainder is 210 after subtracting 4890 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

In conclusion, the division gives 103383.48466 with a balance of 0.00021.
