Let's divide 68397168 by 452
The aim is to understand the frequency of 452 in 68397168.

Going ahead to step 1:
452 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 452

Advancing to step 2:
68 divided by 452 is 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Grab the next digit (3) from the dividend, add it to 68, then carry on: 683 / 452

On to step 3:
452 can be fit into 683 1 times, resulting in a remainder of 231.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 452 from 683 and we're left with 231.
Bring next digit (9) of the dividend behind the 231 and repeat the process: 2319 / 452

Step 4:
2319 divided by 452 is 5 with a remainder of 59.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 2260 from 2319 and we're left with 59.
Append the next digit (7) from the dividend to 59 and continue with: 597 / 452

On to step 5:
452 goes into 597 1 times with a remainder of 145.
Write down 1 as next digit of the result. 
Result so far: 151.0
Deduct 452 from 597 and we're left with 145.
Append the next digit (1) from the dividend to 145 and continue with: 1451 / 452

Advancing to step 6:
If we divide 1451 by 452, we get 3 and a remainder of 95.
Write down 3 as next digit of the result. 
Result so far: 1513.0
Deduct 1356 from 1451 and we're left with 95.
Include the next digit (6) from the dividend after 95, then repeat: 956 / 452

Let's proceed to step 7:
The number 452 fits into 956 2 times, leaving a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 15132.0
Deduct 904 from 956 and we're left with 52.
Append the next digit (8) from the dividend to 52 and continue with: 528 / 452

Going ahead to step 8:
When dividing 528 by 452, we get 1 with a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 151321.0
The remainder is 76 after subtracting 452 from 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 9:
760 divided by 452 is 1 with a remainder of 308.
The number 1 becomes the next digit in our result. 
Result so far: 151321.1
The remainder is 308 after subtracting 452 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 10:
452 can be fit into 3080 6 times, resulting in a remainder of 368.
The number 6 becomes the next digit in our result. 
Result so far: 151321.16
If we subtract 2712 from 3080, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 11:
452 goes into 3680 8 times with a remainder of 64.
The next digit of our result is 8. 
Result so far: 151321.168
If we take 3616 away from 3680, we end up 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.

On to step 12:
640 divided by 452 is 1 with a remainder of 188.
Write down 1 as next digit of the result. 
Result so far: 151321.1681
If we take 452 away from 640, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 13:
The number 452 fits into 1880 4 times, leaving a remainder of 72.
The next digit of our result is 4. 
Result so far: 151321.16814
If we take 1808 away from 1880, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 14:
452 can be fit into 720 1 times, resulting in a remainder of 268.
Record the quotient 1 as the next digit in the result. 
Result so far: 151321.168141
Subtract 452 from 720 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 15:
The number 452 fits into 2680 5 times, leaving a remainder of 420.
Put 5 as the next digit of the answer. 
Result so far: 151321.1681415
Subtracting 2260 from 2680 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 16:
452 goes into 4200 9 times with a remainder of 132.
Put 9 as the next digit of the answer. 
Result so far: 151321.16814159
The remainder is 132 after subtracting 4068 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final outcome is 151321.16814159, with a leftover of 1.32e-07.
