We're dividing 24746136 by 621 
The aim is to understand the frequency of 621 in 24746136.

Step 1:
When dividing 2 by 621, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 621

Step 2:
When dividing 24 by 621, we get 0 with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Grab the next digit (7) from the dividend, add it to 24, then carry on: 247 / 621

Step 3:
247 divided by 621 is 0 with a remainder of 247.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 247 after subtracting 0 from 247.
Append the next digit (4) from the dividend to 247 and continue with: 2474 / 621

Advancing to step 4:
When dividing 2474 by 621, we get 3 with a remainder of 611.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 611 after subtracting 1863 from 2474.
Grab the next digit (6) from the dividend, add it to 611, then carry on: 6116 / 621

Going ahead to step 5:
621 can be fit into 6116 9 times, resulting in a remainder of 527.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we subtract 5589 from 6116, we get 527.
Fetch the next digit (1) from the dividend, attach it to 527 and continue: 5271 / 621

On to step 6:
621 can be fit into 5271 8 times, resulting in a remainder of 303.
Record the quotient 8 as the next digit in the result. 
Result so far: 398.0
Deduct 4968 from 5271 and we're left with 303.
Append the next digit (3) from the dividend to 303 and continue with: 3033 / 621

Step 7:
The number 621 fits into 3033 4 times, leaving a remainder of 549.
The next digit of our result is 4. 
Result so far: 3984.0
Deduct 2484 from 3033 and we're left with 549.
Include the next digit (6) from the dividend after 549, then repeat: 5496 / 621

Advancing to step 8:
621 goes into 5496 8 times with a remainder of 528.
Use 8 as the next digit of our solution. 
Result so far: 39848.0
Deduct 4968 from 5496 and we're left with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Advancing to step 9:
The number 621 fits into 5280 8 times, leaving a remainder of 312.
Write down 8 as next digit of the result. 
Result so far: 39848.8
Subtract 4968 from 5280 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 10:
When dividing 3120 by 621, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 39848.85
If we subtract 3105 from 3120, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
150 divided by 621 is 0 with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 39848.85
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 12:
1500 divided by 621 is 2 with a remainder of 258.
Use 2 as the next digit of our solution. 
Result so far: 39848.8502
The remainder is 258 after subtracting 1242 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 13:
621 can be fit into 2580 4 times, resulting in a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 39848.85024
Deduct 2484 from 2580 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 14:
960 divided by 621 is 1 with a remainder of 339.
Use 1 as the next digit of our solution. 
Result so far: 39848.850241
The remainder is 339 after subtracting 621 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Going ahead to step 15:
When dividing 3390 by 621, we get 5 with a remainder of 285.
Write down 5 as next digit of the result. 
Result so far: 39848.8502415
Subtracting 3105 from 3390 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 16:
If we divide 2850 by 621, we get 4 and a remainder of 366.
Put 4 as the next digit of the answer. 
Result so far: 39848.85024154
The remainder is 366 after subtracting 2484 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

The quotient of the division is 39848.85024154, and the remainder is 3.66e-07.
