We're dividing 63953951 by 333 
The aim is to understand the frequency of 333 in 63953951.

Advancing to step 1:
333 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 333

Let's proceed to step 2:
63 divided by 333 is 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 333

Advancing to step 3:
If we divide 639 by 333, we get 1 and a remainder of 306.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 333 from 639, we get 306.
Append the next digit (5) from the dividend to 306 and continue with: 3065 / 333

Moving on to step 4:
3065 divided by 333 is 9 with a remainder of 68.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 68 after subtracting 2997 from 3065.
Include the next digit (3) from the dividend after 68, then repeat: 683 / 333

On to step 5:
333 can be fit into 683 2 times, resulting in a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
If we subtract 666 from 683, we get 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 333

On to step 6:
The number 333 fits into 179 0 times, leaving a remainder of 179.
Use 0 as the next digit of our solution. 
Result so far: 1920.0
Subtracting 0 from 179 leaves us with 179.
Bring next digit (5) of the dividend behind the 179 and repeat the process: 1795 / 333

Let's proceed to step 7:
When dividing 1795 by 333, we get 5 with a remainder of 130.
Put 5 as the next digit of the answer. 
Result so far: 19205.0
If we take 1665 away from 1795, we end up with 130.
Fetch the next digit (1) from the dividend, attach it to 130 and continue: 1301 / 333

Step 8:
333 goes into 1301 3 times with a remainder of 302.
Record the quotient 3 as the next digit in the result. 
Result so far: 192053.0
Subtracting 999 from 1301 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 9:
3020 divided by 333 is 9 with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 192053.9
Subtracting 2997 from 3020 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
The number 333 fits into 230 0 times, leaving a remainder of 230.
The next digit of our result is 0. 
Result so far: 192053.9
If we subtract 0 from 230, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 11:
If we divide 2300 by 333, we get 6 and a remainder of 302.
Use 6 as the next digit of our solution. 
Result so far: 192053.906
Deduct 1998 from 2300 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Let's proceed to step 12:
3020 divided by 333 is 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 192053.9069
Subtracting 2997 from 3020 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 13:
333 can be fit into 230 0 times, resulting in a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 192053.9069
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 14:
If we divide 2300 by 333, we get 6 and a remainder of 302.
The number 6 becomes the next digit in our result. 
Result so far: 192053.906906
Subtracting 1998 from 2300 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Let's proceed to step 15:
If we divide 3020 by 333, we get 9 and a remainder of 23.
The next digit of our result is 9. 
Result so far: 192053.9069069
Deduct 2997 from 3020 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 16:
The number 333 fits into 230 0 times, leaving a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 192053.9069069
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The quotient of the division is 192053.9069069, and the remainder is 2.3e-07.
