We look at the division of 60600645 by 453 
The aim is to understand the frequency of 453 in 60600645.

Let's proceed to step 1:
453 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 453

Step 2:
When dividing 60 by 453, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Include the next digit (6) from the dividend after 60, then repeat: 606 / 453

Moving on to step 3:
If we divide 606 by 453, we get 1 and a remainder of 153.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 453 from 606 leaves us with 153.
Take the next digit (0) from the dividend and append it to 153, then repeat: 1530 / 453

On to step 4:
453 goes into 1530 3 times with a remainder of 171.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1359 from 1530 leaves us with 171.
Bring next digit (0) of the dividend behind the 171 and repeat the process: 1710 / 453

Step 5:
453 can be fit into 1710 3 times, resulting in a remainder of 351.
Put 3 as the next digit of the answer. 
Result so far: 133.0
The remainder is 351 after subtracting 1359 from 1710.
Grab the next digit (6) from the dividend, add it to 351, then carry on: 3516 / 453

Moving on to step 6:
The number 453 fits into 3516 7 times, leaving a remainder of 345.
Use 7 as the next digit of our solution. 
Result so far: 1337.0
The remainder is 345 after subtracting 3171 from 3516.
Bring next digit (4) of the dividend behind the 345 and repeat the process: 3454 / 453

Step 7:
453 can be fit into 3454 7 times, resulting in a remainder of 283.
The number 7 becomes the next digit in our result. 
Result so far: 13377.0
If we take 3171 away from 3454, we end up with 283.
Include the next digit (5) from the dividend after 283, then repeat: 2835 / 453

On to step 8:
453 goes into 2835 6 times with a remainder of 117.
Use 6 as the next digit of our solution. 
Result so far: 133776.0
The remainder is 117 after subtracting 2718 from 2835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 9:
When dividing 1170 by 453, we get 2 with a remainder of 264.
Put 2 as the next digit of the answer. 
Result so far: 133776.2
Subtract 906 from 1170 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 10:
2640 divided by 453 is 5 with a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 133776.25
Deduct 2265 from 2640 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 11:
453 can be fit into 3750 8 times, resulting in a remainder of 126.
Write down 8 as next digit of the result. 
Result so far: 133776.258
Subtract 3624 from 3750 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 12:
When dividing 1260 by 453, we get 2 with a remainder of 354.
Record the quotient 2 as the next digit in the result. 
Result so far: 133776.2582
If we subtract 906 from 1260, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

On to step 13:
The number 453 fits into 3540 7 times, leaving a remainder of 369.
Use 7 as the next digit of our solution. 
Result so far: 133776.25827
If we subtract 3171 from 3540, we get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Let's proceed to step 14:
453 can be fit into 3690 8 times, resulting in a remainder of 66.
The next digit of our result is 8. 
Result so far: 133776.258278
Subtracting 3624 from 3690 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 15:
660 divided by 453 is 1 with a remainder of 207.
Use 1 as the next digit of our solution. 
Result so far: 133776.2582781
Deduct 453 from 660 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Moving on to step 16:
2070 divided by 453 is 4 with a remainder of 258.
Use 4 as the next digit of our solution. 
Result so far: 133776.25827814
If we take 1812 away from 2070, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Our division results in 133776.25827814 with a remaining 2.58e-07.
