We're dividing 63035608 by 321 
The aim is to understand the frequency of 321 in 63035608.

Step 1:
The number 321 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 321

On to step 2:
321 goes into 63 0 times with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Append the next digit (0) from the dividend to 63 and continue with: 630 / 321

Going ahead to step 3:
630 divided by 321 is 1 with a remainder of 309.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 321 from 630, we get 309.
Take the next digit (3) from the dividend and append it to 309, then repeat: 3093 / 321

Moving on to step 4:
321 goes into 3093 9 times with a remainder of 204.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 2889 from 3093, we get 204.
Fetch the next digit (5) from the dividend, attach it to 204 and continue: 2045 / 321

On to step 5:
2045 divided by 321 is 6 with a remainder of 119.
Use 6 as the next digit of our solution. 
Result so far: 196.0
Subtract 1926 from 2045 to get 119.
Grab the next digit (6) from the dividend, add it to 119, then carry on: 1196 / 321

Step 6:
1196 divided by 321 is 3 with a remainder of 233.
Write down 3 as next digit of the result. 
Result so far: 1963.0
If we subtract 963 from 1196, we get 233.
Grab the next digit (0) from the dividend, add it to 233, then carry on: 2330 / 321

Going ahead to step 7:
When dividing 2330 by 321, we get 7 with a remainder of 83.
The number 7 becomes the next digit in our result. 
Result so far: 19637.0
Subtracting 2247 from 2330 leaves us with 83.
Include the next digit (8) from the dividend after 83, then repeat: 838 / 321

Step 8:
321 can be fit into 838 2 times, resulting in a remainder of 196.
Use 2 as the next digit of our solution. 
Result so far: 196372.0
If we take 642 away from 838, we end up with 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 9:
321 can be fit into 1960 6 times, resulting in a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 196372.6
Deduct 1926 from 1960 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
The number 321 fits into 340 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 196372.61
Deduct 321 from 340 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
321 goes into 190 0 times with a remainder of 190.
Record the quotient 0 as the next digit in the result. 
Result so far: 196372.61
The remainder is 190 after subtracting 0 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 12:
If we divide 1900 by 321, we get 5 and a remainder of 295.
Use 5 as the next digit of our solution. 
Result so far: 196372.6105
If we take 1605 away from 1900, we end up with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Step 13:
If we divide 2950 by 321, we get 9 and a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 196372.61059
The remainder is 61 after subtracting 2889 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 14:
When dividing 610 by 321, we get 1 with a remainder of 289.
Write down 1 as next digit of the result. 
Result so far: 196372.610591
If we take 321 away from 610, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 15:
2890 divided by 321 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 196372.6105919
Subtracting 2889 from 2890 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 16:
10 divided by 321 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 196372.6105919
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 196372.6105919, and the remainder is 1e-08.
