Let's divide 21213566 by 464
The aim is to understand the frequency of 464 in 21213566.

Moving on to step 1:
The number 464 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 464

On to step 2:
When dividing 21 by 464, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 464

Let's proceed to step 3:
If we divide 212 by 464, we get 0 and a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 212 after subtracting 0 from 212.
Fetch the next digit (1) from the dividend, attach it to 212 and continue: 2121 / 464

Let's proceed to step 4:
When dividing 2121 by 464, we get 4 with a remainder of 265.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 1856 away from 2121, we end up with 265.
Include the next digit (3) from the dividend after 265, then repeat: 2653 / 464

Moving on to step 5:
The number 464 fits into 2653 5 times, leaving a remainder of 333.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtract 2320 from 2653 to get 333.
Take the next digit (5) from the dividend and append it to 333, then repeat: 3335 / 464

On to step 6:
3335 divided by 464 is 7 with a remainder of 87.
Use 7 as the next digit of our solution. 
Result so far: 457.0
If we subtract 3248 from 3335, we get 87.
Fetch the next digit (6) from the dividend, attach it to 87 and continue: 876 / 464

Going ahead to step 7:
464 goes into 876 1 times with a remainder of 412.
Use 1 as the next digit of our solution. 
Result so far: 4571.0
If we subtract 464 from 876, we get 412.
Fetch the next digit (6) from the dividend, attach it to 412 and continue: 4126 / 464

Advancing to step 8:
If we divide 4126 by 464, we get 8 and a remainder of 414.
Write down 8 as next digit of the result. 
Result so far: 45718.0
The remainder is 414 after subtracting 3712 from 4126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Advancing to step 9:
The number 464 fits into 4140 8 times, leaving a remainder of 428.
Write down 8 as next digit of the result. 
Result so far: 45718.8
The remainder is 428 after subtracting 3712 from 4140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 10:
4280 divided by 464 is 9 with a remainder of 104.
Use 9 as the next digit of our solution. 
Result so far: 45718.89
Subtract 4176 from 4280 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 11:
When dividing 1040 by 464, we get 2 with a remainder of 112.
The next digit of our result is 2. 
Result so far: 45718.892
The remainder is 112 after subtracting 928 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 12:
When dividing 1120 by 464, we get 2 with a remainder of 192.
Write down 2 as next digit of the result. 
Result so far: 45718.8922
If we subtract 928 from 1120, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

After the division, we end up with 45718.8922 and a remainder of 0.00192.
