74721802 ÷ 258 
The aim is to understand the frequency of 258 in 74721802.

Moving on to step 1:
If we divide 7 by 258, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 258

Step 2:
258 can be fit into 74 0 times, resulting in a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Bring next digit (7) of the dividend behind the 74 and repeat the process: 747 / 258

Step 3:
When dividing 747 by 258, we get 2 with a remainder of 231.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 516 from 747, we get 231.
Include the next digit (2) from the dividend after 231, then repeat: 2312 / 258

Advancing to step 4:
If we divide 2312 by 258, we get 8 and a remainder of 248.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 2064 from 2312 and we're left with 248.
Fetch the next digit (1) from the dividend, attach it to 248 and continue: 2481 / 258

Moving on to step 5:
2481 divided by 258 is 9 with a remainder of 159.
The next digit of our result is 9. 
Result so far: 289.0
Subtract 2322 from 2481 to get 159.
Bring next digit (8) of the dividend behind the 159 and repeat the process: 1598 / 258

Step 6:
258 goes into 1598 6 times with a remainder of 50.
The next digit of our result is 6. 
Result so far: 2896.0
Subtract 1548 from 1598 to get 50.
Grab the next digit (0) from the dividend, add it to 50, then carry on: 500 / 258

Advancing to step 7:
When dividing 500 by 258, we get 1 with a remainder of 242.
Record the quotient 1 as the next digit in the result. 
Result so far: 28961.0
Subtracting 258 from 500 leaves us with 242.
Take the next digit (2) from the dividend and append it to 242, then repeat: 2422 / 258

Going ahead to step 8:
258 can be fit into 2422 9 times, resulting in a remainder of 100.
Record the quotient 9 as the next digit in the result. 
Result so far: 289619.0
Deduct 2322 from 2422 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 9:
The number 258 fits into 1000 3 times, leaving a remainder of 226.
Write down 3 as next digit of the result. 
Result so far: 289619.3
Subtract 774 from 1000 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 10:
258 goes into 2260 8 times with a remainder of 196.
Put 8 as the next digit of the answer. 
Result so far: 289619.38
The remainder is 196 after subtracting 2064 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 11:
258 goes into 1960 7 times with a remainder of 154.
Put 7 as the next digit of the answer. 
Result so far: 289619.387
Subtract 1806 from 1960 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 12:
1540 divided by 258 is 5 with a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 289619.3875
Deduct 1290 from 1540 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 13:
258 can be fit into 2500 9 times, resulting in a remainder of 178.
Use 9 as the next digit of our solution. 
Result so far: 289619.38759
If we subtract 2322 from 2500, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 14:
258 goes into 1780 6 times with a remainder of 232.
The number 6 becomes the next digit in our result. 
Result so far: 289619.387596
Subtract 1548 from 1780 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 15:
When dividing 2320 by 258, we get 8 with a remainder of 256.
Put 8 as the next digit of the answer. 
Result so far: 289619.3875968
Deduct 2064 from 2320 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 16:
The number 258 fits into 2560 9 times, leaving a remainder of 238.
The number 9 becomes the next digit in our result. 
Result so far: 289619.38759689
Subtract 2322 from 2560 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

In conclusion, the division gives 289619.38759689 with a balance of 2.38e-07.
