We're dividing 17420224 by 258 
We want to figure out the number of times 17420224 can be divided by 258.

Step 1:
258 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 258

Advancing to step 2:
258 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 258

Advancing to step 3:
The number 258 fits into 174 0 times, leaving a remainder of 174.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 174 after subtracting 0 from 174.
Fetch the next digit (2) from the dividend, attach it to 174 and continue: 1742 / 258

Moving on to step 4:
When dividing 1742 by 258, we get 6 with a remainder of 194.
The next digit of our result is 6. 
Result so far: 6.0
If we take 1548 away from 1742, we end up with 194.
Fetch the next digit (0) from the dividend, attach it to 194 and continue: 1940 / 258

On to step 5:
The number 258 fits into 1940 7 times, leaving a remainder of 134.
Use 7 as the next digit of our solution. 
Result so far: 67.0
If we subtract 1806 from 1940, we get 134.
Take the next digit (2) from the dividend and append it to 134, then repeat: 1342 / 258

Let's proceed to step 6:
When dividing 1342 by 258, we get 5 with a remainder of 52.
The number 5 becomes the next digit in our result. 
Result so far: 675.0
If we subtract 1290 from 1342, we get 52.
Include the next digit (2) from the dividend after 52, then repeat: 522 / 258

Moving on to step 7:
258 can be fit into 522 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 6752.0
Deduct 516 from 522 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 258

Step 8:
When dividing 64 by 258, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 67520.0
Subtract 0 from 64 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
When dividing 640 by 258, we get 2 with a remainder of 124.
The next digit of our result is 2. 
Result so far: 67520.2
The remainder is 124 after subtracting 516 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 10:
258 can be fit into 1240 4 times, resulting in a remainder of 208.
Record the quotient 4 as the next digit in the result. 
Result so far: 67520.24
Subtract 1032 from 1240 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 11:
2080 divided by 258 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 67520.248
Deduct 2064 from 2080 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
160 divided by 258 is 0 with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 67520.248
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
When dividing 1600 by 258, we get 6 with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 67520.24806
Subtracting 1548 from 1600 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.

Step 14:
When dividing 520 by 258, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 67520.248062
If we subtract 516 from 520, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 15:
258 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 67520.248062
If we take 0 away from 40, we end up 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.

On to step 16:
258 can be fit into 400 1 times, resulting in a remainder of 142.
Use 1 as the next digit of our solution. 
Result so far: 67520.24806201
The remainder is 142 after subtracting 258 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The final result is 67520.24806201 with a remainder of 1.42e-07.
