58530453 divided by 815 
We want to figure out the number of times 58530453 can be divided by 815.

Moving on to step 1:
When dividing 5 by 815, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 815

Going ahead to step 2:
If we divide 58 by 815, we get 0 and a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Bring next digit (5) of the dividend behind the 58 and repeat the process: 585 / 815

On to step 3:
The number 815 fits into 585 0 times, leaving a remainder of 585.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 585, we get 585.
Append the next digit (3) from the dividend to 585 and continue with: 5853 / 815

Let's proceed to step 4:
815 goes into 5853 7 times with a remainder of 148.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 5705 away from 5853, we end up with 148.
Grab the next digit (0) from the dividend, add it to 148, then carry on: 1480 / 815

Advancing to step 5:
1480 divided by 815 is 1 with a remainder of 665.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Subtract 815 from 1480 to get 665.
Fetch the next digit (4) from the dividend, attach it to 665 and continue: 6654 / 815

Step 6:
815 goes into 6654 8 times with a remainder of 134.
Record the quotient 8 as the next digit in the result. 
Result so far: 718.0
If we take 6520 away from 6654, we end up with 134.
Append the next digit (5) from the dividend to 134 and continue with: 1345 / 815

Step 7:
When dividing 1345 by 815, we get 1 with a remainder of 530.
The next digit of our result is 1. 
Result so far: 7181.0
If we subtract 815 from 1345, we get 530.
Include the next digit (3) from the dividend after 530, then repeat: 5303 / 815

Let's proceed to step 8:
The number 815 fits into 5303 6 times, leaving a remainder of 413.
Put 6 as the next digit of the answer. 
Result so far: 71816.0
If we take 4890 away from 5303, we end up with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Moving on to step 9:
When dividing 4130 by 815, we get 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 71816.5
Deduct 4075 from 4130 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 10:
When dividing 550 by 815, we get 0 with a remainder of 550.
Put 0 as the next digit of the answer. 
Result so far: 71816.5
Deduct 0 from 550 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 11:
815 goes into 5500 6 times with a remainder of 610.
Write down 6 as next digit of the result. 
Result so far: 71816.506
The remainder is 610 after subtracting 4890 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 12:
815 goes into 6100 7 times with a remainder of 395.
The number 7 becomes the next digit in our result. 
Result so far: 71816.5067
The remainder is 395 after subtracting 5705 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Step 13:
815 can be fit into 3950 4 times, resulting in a remainder of 690.
The number 4 becomes the next digit in our result. 
Result so far: 71816.50674
Deduct 3260 from 3950 and we're left 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.

Advancing to step 14:
When dividing 6900 by 815, we get 8 with a remainder of 380.
The next digit of our result is 8. 
Result so far: 71816.506748
If we take 6520 away from 6900, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 15:
The number 815 fits into 3800 4 times, leaving a remainder of 540.
Put 4 as the next digit of the answer. 
Result so far: 71816.5067484
Subtract 3260 from 3800 to 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.

Let's proceed to step 16:
815 can be fit into 5400 6 times, resulting in a remainder of 510.
Put 6 as the next digit of the answer. 
Result so far: 71816.50674846
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.

The final result is 71816.50674846 with a remainder of 5.1e-07.
