We look at the division of 2021912 by 463 
The aim is to understand the frequency of 463 in 2021912.

On to step 1:
When dividing 2 by 463, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 463

Advancing to step 2:
20 divided by 463 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 463

Let's proceed to step 3:
If we divide 202 by 463, we get 0 and a remainder of 202.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 202 leaves us with 202.
Grab the next digit (1) from the dividend, add it to 202, then carry on: 2021 / 463

Going ahead to step 4:
463 goes into 2021 4 times with a remainder of 169.
The next digit of our result is 4. 
Result so far: 4.0
If we take 1852 away from 2021, we end up with 169.
Take the next digit (9) from the dividend and append it to 169, then repeat: 1699 / 463

Moving on to step 5:
The number 463 fits into 1699 3 times, leaving a remainder of 310.
The next digit of our result is 3. 
Result so far: 43.0
If we take 1389 away from 1699, we end up with 310.
Append the next digit (1) from the dividend to 310 and continue with: 3101 / 463

Moving on to step 6:
463 goes into 3101 6 times with a remainder of 323.
Put 6 as the next digit of the answer. 
Result so far: 436.0
The remainder is 323 after subtracting 2778 from 3101.
Fetch the next digit (2) from the dividend, attach it to 323 and continue: 3232 / 463

Let's proceed to step 7:
463 can be fit into 3232 6 times, resulting in a remainder of 454.
Use 6 as the next digit of our solution. 
Result so far: 4366.0
Deduct 2778 from 3232 and we're left with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 8:
463 can be fit into 4540 9 times, resulting in a remainder of 373.
The number 9 becomes the next digit in our result. 
Result so far: 4366.9
The remainder is 373 after subtracting 4167 from 4540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Advancing to step 9:
3730 divided by 463 is 8 with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 4366.98
Deduct 3704 from 3730 and we're left 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.

On to step 10:
When dividing 260 by 463, we get 0 with a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 4366.98
If we take 0 away from 260, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 11:
2600 divided by 463 is 5 with a remainder of 285.
Use 5 as the next digit of our solution. 
Result so far: 4366.9805
If we subtract 2315 from 2600, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 12:
The number 463 fits into 2850 6 times, leaving a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 4366.98056
Subtracting 2778 from 2850 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 13:
720 divided by 463 is 1 with a remainder of 257.
Use 1 as the next digit of our solution. 
Result so far: 4366.980561
The remainder is 257 after subtracting 463 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Step 14:
If we divide 2570 by 463, we get 5 and a remainder of 255.
The next digit of our result is 5. 
Result so far: 4366.9805615
Subtract 2315 from 2570 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 15:
463 goes into 2550 5 times with a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 4366.98056155
The remainder is 235 after subtracting 2315 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

The final result is 4366.98056155 with a remainder of 2.35e-07.
