We're dividing 64196121 by 452 
The aim is to understand the frequency of 452 in 64196121.

Advancing to step 1:
6 divided by 452 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 452

Moving on to step 2:
64 divided by 452 is 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Include the next digit (1) from the dividend after 64, then repeat: 641 / 452

Let's proceed to step 3:
452 goes into 641 1 times with a remainder of 189.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 189 after subtracting 452 from 641.
Bring next digit (9) of the dividend behind the 189 and repeat the process: 1899 / 452

Advancing to step 4:
If we divide 1899 by 452, we get 4 and a remainder of 91.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 1808 from 1899, we get 91.
Append the next digit (6) from the dividend to 91 and continue with: 916 / 452

Going ahead to step 5:
If we divide 916 by 452, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 142.0
Deduct 904 from 916 and we're left with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 452

Going ahead to step 6:
If we divide 121 by 452, we get 0 and a remainder of 121.
The next digit of our result is 0. 
Result so far: 1420.0
If we subtract 0 from 121, we get 121.
Include the next digit (2) from the dividend after 121, then repeat: 1212 / 452

Advancing to step 7:
452 goes into 1212 2 times with a remainder of 308.
Write down 2 as next digit of the result. 
Result so far: 14202.0
The remainder is 308 after subtracting 904 from 1212.
Take the next digit (1) from the dividend and append it to 308, then repeat: 3081 / 452

Advancing to step 8:
The number 452 fits into 3081 6 times, leaving a remainder of 369.
Put 6 as the next digit of the answer. 
Result so far: 142026.0
If we take 2712 away from 3081, we end up with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

On to step 9:
The number 452 fits into 3690 8 times, leaving a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 142026.8
Subtract 3616 from 3690 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 10:
452 goes into 740 1 times with a remainder of 288.
Record the quotient 1 as the next digit in the result. 
Result so far: 142026.81
Deduct 452 from 740 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 11:
The number 452 fits into 2880 6 times, leaving a remainder of 168.
Use 6 as the next digit of our solution. 
Result so far: 142026.816
The remainder is 168 after subtracting 2712 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 12:
The number 452 fits into 1680 3 times, leaving a remainder of 324.
Use 3 as the next digit of our solution. 
Result so far: 142026.8163
Subtract 1356 from 1680 to get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 13:
452 can be fit into 3240 7 times, resulting in a remainder of 76.
Put 7 as the next digit of the answer. 
Result so far: 142026.81637
Subtract 3164 from 3240 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 14:
When dividing 760 by 452, we get 1 with a remainder of 308.
Use 1 as the next digit of our solution. 
Result so far: 142026.816371
Deduct 452 from 760 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 15:
The number 452 fits into 3080 6 times, leaving a remainder of 368.
The next digit of our result is 6. 
Result so far: 142026.8163716
The remainder is 368 after subtracting 2712 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 16:
If we divide 3680 by 452, we get 8 and a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 142026.81637168
Subtracting 3616 from 3680 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 142026.81637168 with a remainder of 6.4e-08.
