We look at the division of 58054809 by 721 
We want to figure out the number of times 58054809 can be divided by 721.

On to step 1:
If we divide 5 by 721, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 721

Step 2:
The number 721 fits into 58 0 times, leaving a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Take the next digit (0) from the dividend and append it to 58, then repeat: 580 / 721

On to step 3:
721 goes into 580 0 times with a remainder of 580.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 580, we end up with 580.
Grab the next digit (5) from the dividend, add it to 580, then carry on: 5805 / 721

Going ahead to step 4:
When dividing 5805 by 721, we get 8 with a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 5768 from 5805 leaves us with 37.
Append the next digit (4) from the dividend to 37 and continue with: 374 / 721

Step 5:
The number 721 fits into 374 0 times, leaving a remainder of 374.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Deduct 0 from 374 and we're left with 374.
Include the next digit (8) from the dividend after 374, then repeat: 3748 / 721

On to step 6:
721 can be fit into 3748 5 times, resulting in a remainder of 143.
The next digit of our result is 5. 
Result so far: 805.0
The remainder is 143 after subtracting 3605 from 3748.
Bring next digit (0) of the dividend behind the 143 and repeat the process: 1430 / 721

Let's proceed to step 7:
721 goes into 1430 1 times with a remainder of 709.
Write down 1 as next digit of the result. 
Result so far: 8051.0
The remainder is 709 after subtracting 721 from 1430.
Bring next digit (9) of the dividend behind the 709 and repeat the process: 7099 / 721

Advancing to step 8:
The number 721 fits into 7099 9 times, leaving a remainder of 610.
Put 9 as the next digit of the answer. 
Result so far: 80519.0
Deduct 6489 from 7099 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Going ahead to step 9:
When dividing 6100 by 721, we get 8 with a remainder of 332.
Use 8 as the next digit of our solution. 
Result so far: 80519.8
If we take 5768 away from 6100, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Let's proceed to step 10:
721 can be fit into 3320 4 times, resulting in a remainder of 436.
The number 4 becomes the next digit in our result. 
Result so far: 80519.84
If we take 2884 away from 3320, we end up with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 11:
4360 divided by 721 is 6 with a remainder of 34.
The next digit of our result is 6. 
Result so far: 80519.846
The remainder is 34 after subtracting 4326 from 4360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
721 goes into 340 0 times with a remainder of 340.
The next digit of our result is 0. 
Result so far: 80519.846
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 13:
When dividing 3400 by 721, we get 4 with a remainder of 516.
Record the quotient 4 as the next digit in the result. 
Result so far: 80519.84604
If we take 2884 away from 3400, we end up with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 14:
721 goes into 5160 7 times with a remainder of 113.
The number 7 becomes the next digit in our result. 
Result so far: 80519.846047
Deduct 5047 from 5160 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 15:
If we divide 1130 by 721, we get 1 and a remainder of 409.
Record the quotient 1 as the next digit in the result. 
Result so far: 80519.8460471
If we take 721 away from 1130, we end up with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Going ahead to step 16:
721 can be fit into 4090 5 times, resulting in a remainder of 485.
Put 5 as the next digit of the answer. 
Result so far: 80519.84604715
If we subtract 3605 from 4090, we get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

The final result is 80519.84604715 with a remainder of 4.85e-07.
