58612039 ÷ 73 
We want to figure out the number of times 58612039 can be divided by 73.

Step 1:
When dividing 5 by 73, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 73

Let's proceed to step 2:
58 divided by 73 is 0 with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Append the next digit (6) from the dividend to 58 and continue with: 586 / 73

Let's proceed to step 3:
The number 73 fits into 586 8 times, leaving a remainder of 2.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 2 after subtracting 584 from 586.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 73

Step 4:
73 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 73

Moving on to step 5:
73 can be fit into 212 2 times, resulting in a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 802.0
Deduct 146 from 212 and we're left with 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 73

Step 6:
If we divide 660 by 73, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 8029.0
Subtract 657 from 660 to get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 73

Going ahead to step 7:
The number 73 fits into 33 0 times, leaving a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 80290.0
The remainder is 33 after subtracting 0 from 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 73

On to step 8:
The number 73 fits into 339 4 times, leaving a remainder of 47.
The number 4 becomes the next digit in our result. 
Result so far: 802904.0
Subtracting 292 from 339 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 9:
470 divided by 73 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 802904.6
Subtracting 438 from 470 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
320 divided by 73 is 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 802904.64
If we take 292 away from 320, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
73 can be fit into 280 3 times, resulting in a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 802904.643
If we subtract 219 from 280, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 12:
When dividing 610 by 73, we get 8 with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 802904.6438
The remainder is 26 after subtracting 584 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
73 can be fit into 260 3 times, resulting in a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 802904.64383
Deduct 219 from 260 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 14:
73 can be fit into 410 5 times, resulting in a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 802904.643835
If we take 365 away from 410, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 15:
If we divide 450 by 73, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 802904.6438356
If we subtract 438 from 450, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 16:
If we divide 120 by 73, we get 1 and a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 802904.64383561
Deduct 73 from 120 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final result is 802904.64383561 with a remainder of 4.7e-08.
