We're dividing 36364190 by 643 
The aim is to understand the frequency of 643 in 36364190.

On to step 1:
If we divide 3 by 643, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 643

Going ahead to step 2:
643 can be fit into 36 0 times, resulting in a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Grab the next digit (3) from the dividend, add it to 36, then carry on: 363 / 643

Let's proceed to step 3:
When dividing 363 by 643, we get 0 with a remainder of 363.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 363 after subtracting 0 from 363.
Take the next digit (6) from the dividend and append it to 363, then repeat: 3636 / 643

Going ahead to step 4:
The number 643 fits into 3636 5 times, leaving a remainder of 421.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 421 after subtracting 3215 from 3636.
Take the next digit (4) from the dividend and append it to 421, then repeat: 4214 / 643

Advancing to step 5:
The number 643 fits into 4214 6 times, leaving a remainder of 356.
The next digit of our result is 6. 
Result so far: 56.0
Subtract 3858 from 4214 to get 356.
Fetch the next digit (1) from the dividend, attach it to 356 and continue: 3561 / 643

On to step 6:
When dividing 3561 by 643, we get 5 with a remainder of 346.
Use 5 as the next digit of our solution. 
Result so far: 565.0
Subtracting 3215 from 3561 leaves us with 346.
Include the next digit (9) from the dividend after 346, then repeat: 3469 / 643

Let's proceed to step 7:
If we divide 3469 by 643, we get 5 and a remainder of 254.
The number 5 becomes the next digit in our result. 
Result so far: 5655.0
Subtracting 3215 from 3469 leaves us with 254.
Bring next digit (0) of the dividend behind the 254 and repeat the process: 2540 / 643

Moving on to step 8:
When dividing 2540 by 643, we get 3 with a remainder of 611.
The next digit of our result is 3. 
Result so far: 56553.0
The remainder is 611 after subtracting 1929 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Advancing to step 9:
643 can be fit into 6110 9 times, resulting in a remainder of 323.
Write down 9 as next digit of the result. 
Result so far: 56553.9
If we take 5787 away from 6110, we end up with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Advancing to step 10:
If we divide 3230 by 643, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 56553.95
The remainder is 15 after subtracting 3215 from 3230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
643 goes into 150 0 times with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 56553.95
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 12:
The number 643 fits into 1500 2 times, leaving a remainder of 214.
The next digit of our result is 2. 
Result so far: 56553.9502
Subtract 1286 from 1500 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 13:
643 can be fit into 2140 3 times, resulting in a remainder of 211.
Record the quotient 3 as the next digit in the result. 
Result so far: 56553.95023
If we subtract 1929 from 2140, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Let's proceed to step 14:
2110 divided by 643 is 3 with a remainder of 181.
The next digit of our result is 3. 
Result so far: 56553.950233
If we subtract 1929 from 2110, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Our division results in 56553.950233 with a remaining 1.81e-05.
