We look at the division of 510291 by 58 
We want to figure out the number of times 510291 can be divided by 58.

On to step 1:
The number 58 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 58

Step 2:
58 goes into 51 0 times with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 58

Advancing to step 3:
The number 58 fits into 510 8 times, leaving a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 464 from 510 to get 46.
Take the next digit (2) from the dividend and append it to 46, then repeat: 462 / 58

Let's proceed to step 4:
462 divided by 58 is 7 with a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Subtracting 406 from 462 leaves us with 56.
Bring next digit (9) of the dividend behind the 56 and repeat the process: 569 / 58

Advancing to step 5:
When dividing 569 by 58, we get 9 with a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 879.0
Deduct 522 from 569 and we're left with 47.
Include the next digit (1) from the dividend after 47, then repeat: 471 / 58

Going ahead to step 6:
The number 58 fits into 471 8 times, leaving a remainder of 7.
The next digit of our result is 8. 
Result so far: 8798.0
Deduct 464 from 471 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
58 goes into 70 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 8798.1
Subtracting 58 from 70 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
120 divided by 58 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 8798.12
If we take 116 away from 120, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
If we divide 40 by 58, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 8798.12
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
58 goes into 400 6 times with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 8798.1206
Subtracting 348 from 400 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
The number 58 fits into 520 8 times, leaving a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 8798.12068
The remainder is 56 after subtracting 464 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 12:
58 goes into 560 9 times with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 8798.120689
Subtracting 522 from 560 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
58 can be fit into 380 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 8798.1206896
If we subtract 348 from 380, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
320 divided by 58 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 8798.12068965
Subtract 290 from 320 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 8798.12068965 and a remainder of 3e-08.
