Let's divide 39840053 by 258
The aim is to understand the frequency of 258 in 39840053.

Let's proceed to step 1:
If we divide 3 by 258, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 258

Step 2:
The number 258 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (8) from the dividend, attach it to 39 and continue: 398 / 258

On to step 3:
When dividing 398 by 258, we get 1 with a remainder of 140.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 258 away from 398, we end up with 140.
Fetch the next digit (4) from the dividend, attach it to 140 and continue: 1404 / 258

Moving on to step 4:
258 goes into 1404 5 times with a remainder of 114.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 1290 from 1404 leaves us with 114.
Bring next digit (0) of the dividend behind the 114 and repeat the process: 1140 / 258

Let's proceed to step 5:
258 can be fit into 1140 4 times, resulting in a remainder of 108.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
Subtract 1032 from 1140 to get 108.
Append the next digit (0) from the dividend to 108 and continue with: 1080 / 258

Step 6:
If we divide 1080 by 258, we get 4 and a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 1544.0
The remainder is 48 after subtracting 1032 from 1080.
Grab the next digit (5) from the dividend, add it to 48, then carry on: 485 / 258

Advancing to step 7:
The number 258 fits into 485 1 times, leaving a remainder of 227.
Record the quotient 1 as the next digit in the result. 
Result so far: 15441.0
Subtract 258 from 485 to get 227.
Fetch the next digit (3) from the dividend, attach it to 227 and continue: 2273 / 258

Step 8:
258 goes into 2273 8 times with a remainder of 209.
Put 8 as the next digit of the answer. 
Result so far: 154418.0
Subtracting 2064 from 2273 leaves us with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 9:
258 can be fit into 2090 8 times, resulting in a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 154418.8
Subtracting 2064 from 2090 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
The number 258 fits into 260 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 154418.81
Subtracting 258 from 260 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
258 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 154418.81
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
258 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 154418.81
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 154418.81, and the remainder is 0.002.
