We look at the division of 73039061 by 258 
We're looking to find how many times 258 goes into 73039061.

Let's proceed to step 1:
When dividing 7 by 258, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 258

On to step 2:
258 goes into 73 0 times with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Fetch the next digit (0) from the dividend, attach it to 73 and continue: 730 / 258

Let's proceed to step 3:
The number 258 fits into 730 2 times, leaving a remainder of 214.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 516 from 730 leaves us with 214.
Fetch the next digit (3) from the dividend, attach it to 214 and continue: 2143 / 258

Advancing to step 4:
If we divide 2143 by 258, we get 8 and a remainder of 79.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtract 2064 from 2143 to get 79.
Bring next digit (9) of the dividend behind the 79 and repeat the process: 799 / 258

Going ahead to step 5:
When dividing 799 by 258, we get 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 283.0
Deduct 774 from 799 and we're left with 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 258

Going ahead to step 6:
If we divide 250 by 258, we get 0 and a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 2830.0
If we take 0 away from 250, we end up with 250.
Grab the next digit (6) from the dividend, add it to 250, then carry on: 2506 / 258

Advancing to step 7:
258 can be fit into 2506 9 times, resulting in a remainder of 184.
The next digit of our result is 9. 
Result so far: 28309.0
If we take 2322 away from 2506, we end up with 184.
Append the next digit (1) from the dividend to 184 and continue with: 1841 / 258

Step 8:
258 can be fit into 1841 7 times, resulting in a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 283097.0
If we subtract 1806 from 1841, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
350 divided by 258 is 1 with a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 283097.1
Subtract 258 from 350 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 10:
When dividing 920 by 258, we get 3 with a remainder of 146.
Put 3 as the next digit of the answer. 
Result so far: 283097.13
Deduct 774 from 920 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 11:
258 can be fit into 1460 5 times, resulting in a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 283097.135
If we subtract 1290 from 1460, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 12:
258 goes into 1700 6 times with a remainder of 152.
Record the quotient 6 as the next digit in the result. 
Result so far: 283097.1356
Subtract 1548 from 1700 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 13:
When dividing 1520 by 258, we get 5 with a remainder of 230.
Put 5 as the next digit of the answer. 
Result so far: 283097.13565
If we subtract 1290 from 1520, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 14:
2300 divided by 258 is 8 with a remainder of 236.
The next digit of our result is 8. 
Result so far: 283097.135658
Subtract 2064 from 2300 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 15:
When dividing 2360 by 258, we get 9 with a remainder of 38.
The next digit of our result is 9. 
Result so far: 283097.1356589
Subtracting 2322 from 2360 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.

Going ahead to step 16:
The number 258 fits into 380 1 times, leaving a remainder of 122.
The number 1 becomes the next digit in our result. 
Result so far: 283097.13565891
Deduct 258 from 380 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

The final outcome is 283097.13565891, with a leftover of 1.22e-07.
