Let's divide 21417106 by 303
The aim is to understand the frequency of 303 in 21417106.

Advancing to step 1:
303 can be fit into 2 0 times, resulting in 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.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 303

Advancing to step 2:
303 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 303

Moving on to step 3:
303 can be fit into 214 0 times, resulting in a remainder of 214.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 214 leaves us with 214.
Include the next digit (1) from the dividend after 214, then repeat: 2141 / 303

Let's proceed to step 4:
The number 303 fits into 2141 7 times, leaving a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 2121 from 2141 and we're left with 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 303

Advancing to step 5:
If we divide 207 by 303, we get 0 and a remainder of 207.
Put 0 as the next digit of the answer. 
Result so far: 70.0
The remainder is 207 after subtracting 0 from 207.
Grab the next digit (1) from the dividend, add it to 207, then carry on: 2071 / 303

Let's proceed to step 6:
303 goes into 2071 6 times with a remainder of 253.
Record the quotient 6 as the next digit in the result. 
Result so far: 706.0
Subtracting 1818 from 2071 leaves us with 253.
Include the next digit (0) from the dividend after 253, then repeat: 2530 / 303

Step 7:
2530 divided by 303 is 8 with a remainder of 106.
Record the quotient 8 as the next digit in the result. 
Result so far: 7068.0
If we subtract 2424 from 2530, we get 106.
Include the next digit (6) from the dividend after 106, then repeat: 1066 / 303

Advancing to step 8:
The number 303 fits into 1066 3 times, leaving a remainder of 157.
Write down 3 as next digit of the result. 
Result so far: 70683.0
Deduct 909 from 1066 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 9:
The number 303 fits into 1570 5 times, leaving a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 70683.5
Subtract 1515 from 1570 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 10:
When dividing 550 by 303, we get 1 with a remainder of 247.
Use 1 as the next digit of our solution. 
Result so far: 70683.51
The remainder is 247 after subtracting 303 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 11:
303 can be fit into 2470 8 times, resulting in a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 70683.518
Subtract 2424 from 2470 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
If we divide 460 by 303, we get 1 and a remainder of 157.
Use 1 as the next digit of our solution. 
Result so far: 70683.5181
Deduct 303 from 460 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 13:
The number 303 fits into 1570 5 times, leaving a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 70683.51815
Subtract 1515 from 1570 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 14:
The number 303 fits into 550 1 times, leaving a remainder of 247.
The next digit of our result is 1. 
Result so far: 70683.518151
Subtracting 303 from 550 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Moving on to step 15:
303 can be fit into 2470 8 times, resulting in a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 70683.5181518
Subtract 2424 from 2470 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 16:
If we divide 460 by 303, we get 1 and a remainder of 157.
The next digit of our result is 1. 
Result so far: 70683.51815181
If we take 303 away from 460, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

The final outcome is 70683.51815181, with a leftover of 1.57e-07.
