21418483 ÷ 363 
The aim is to understand the frequency of 363 in 21418483.

On to step 1:
The number 363 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 363

Let's proceed to step 2:
When dividing 21 by 363, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 363

Let's proceed to step 3:
If we divide 214 by 363, we get 0 and a remainder of 214.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 214 and we're left with 214.
Bring next digit (1) of the dividend behind the 214 and repeat the process: 2141 / 363

Going ahead to step 4:
When dividing 2141 by 363, we get 5 with a remainder of 326.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 1815 from 2141 leaves us with 326.
Include the next digit (8) from the dividend after 326, then repeat: 3268 / 363

On to step 5:
3268 divided by 363 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 59.0
Deduct 3267 from 3268 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 363

Going ahead to step 6:
14 divided by 363 is 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 590.0
If we take 0 away from 14, we end up with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 363

Let's proceed to step 7:
If we divide 148 by 363, we get 0 and a remainder of 148.
The next digit of our result is 0. 
Result so far: 5900.0
The remainder is 148 after subtracting 0 from 148.
Fetch the next digit (3) from the dividend, attach it to 148 and continue: 1483 / 363

Moving on to step 8:
If we divide 1483 by 363, we get 4 and a remainder of 31.
The number 4 becomes the next digit in our result. 
Result so far: 59004.0
The remainder is 31 after subtracting 1452 from 1483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
363 can be fit into 310 0 times, resulting in a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 59004.0
Deduct 0 from 310 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 10:
If we divide 3100 by 363, we get 8 and a remainder of 196.
Record the quotient 8 as the next digit in the result. 
Result so far: 59004.08
If we subtract 2904 from 3100, we get 196.
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:
If we divide 1960 by 363, we get 5 and a remainder of 145.
The number 5 becomes the next digit in our result. 
Result so far: 59004.085
The remainder is 145 after subtracting 1815 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 12:
1450 divided by 363 is 3 with a remainder of 361.
Record the quotient 3 as the next digit in the result. 
Result so far: 59004.0853
Subtracting 1089 from 1450 leaves us with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Going ahead to step 13:
If we divide 3610 by 363, we get 9 and a remainder of 343.
Record the quotient 9 as the next digit in the result. 
Result so far: 59004.08539
If we subtract 3267 from 3610, we get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Moving on to step 14:
If we divide 3430 by 363, we get 9 and a remainder of 163.
The number 9 becomes the next digit in our result. 
Result so far: 59004.085399
If we take 3267 away from 3430, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

The final outcome is 59004.085399, with a leftover of 1.63e-05.
