We're dividing 63373607 by 300 
The aim is to understand the frequency of 300 in 63373607.

Advancing to step 1:
300 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 300

Moving on to step 2:
63 divided by 300 is 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Append the next digit (3) from the dividend to 63 and continue with: 633 / 300

On to step 3:
300 can be fit into 633 2 times, resulting in a remainder of 33.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 33 after subtracting 600 from 633.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 300

Going ahead to step 4:
When dividing 337 by 300, we get 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 37 after subtracting 300 from 337.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 300

On to step 5:
If we divide 373 by 300, we get 1 and a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 211.0
If we take 300 away from 373, we end up with 73.
Fetch the next digit (6) from the dividend, attach it to 73 and continue: 736 / 300

Moving on to step 6:
300 goes into 736 2 times with a remainder of 136.
Put 2 as the next digit of the answer. 
Result so far: 2112.0
Subtract 600 from 736 to get 136.
Append the next digit (0) from the dividend to 136 and continue with: 1360 / 300

On to step 7:
300 can be fit into 1360 4 times, resulting in a remainder of 160.
Record the quotient 4 as the next digit in the result. 
Result so far: 21124.0
Subtract 1200 from 1360 to get 160.
Grab the next digit (7) from the dividend, add it to 160, then carry on: 1607 / 300

Step 8:
The number 300 fits into 1607 5 times, leaving a remainder of 107.
Put 5 as the next digit of the answer. 
Result so far: 211245.0
If we take 1500 away from 1607, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 9:
The number 300 fits into 1070 3 times, leaving a remainder of 170.
The number 3 becomes the next digit in our result. 
Result so far: 211245.3
Subtract 900 from 1070 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 10:
300 goes into 1700 5 times with a remainder of 200.
The next digit of our result is 5. 
Result so far: 211245.35
The remainder is 200 after subtracting 1500 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
The number 300 fits into 2000 6 times, leaving a remainder of 200.
Record the quotient 6 as the next digit in the result. 
Result so far: 211245.356
Subtract 1800 from 2000 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 12:
2000 divided by 300 is 6 with a remainder of 200.
Write down 6 as next digit of the result. 
Result so far: 211245.3566
The remainder is 200 after subtracting 1800 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 211245.3566, with a leftover of 0.002.
