82720389 ÷ 452 
The aim is to understand the frequency of 452 in 82720389.

On to step 1:
452 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 452

Going ahead to step 2:
82 divided by 452 is 0 with a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Bring next digit (7) of the dividend behind the 82 and repeat the process: 827 / 452

Going ahead to step 3:
When dividing 827 by 452, we get 1 with a remainder of 375.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 452 from 827 leaves us with 375.
Append the next digit (2) from the dividend to 375 and continue with: 3752 / 452

Going ahead to step 4:
3752 divided by 452 is 8 with a remainder of 136.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 3616 from 3752 leaves us with 136.
Append the next digit (0) from the dividend to 136 and continue with: 1360 / 452

Advancing to step 5:
The number 452 fits into 1360 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 183.0
Subtracting 1356 from 1360 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 452

Let's proceed to step 6:
If we divide 43 by 452, we get 0 and a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 1830.0
Subtract 0 from 43 to get 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 452

On to step 7:
452 goes into 438 0 times with a remainder of 438.
The next digit of our result is 0. 
Result so far: 18300.0
Subtract 0 from 438 to get 438.
Grab the next digit (9) from the dividend, add it to 438, then carry on: 4389 / 452

On to step 8:
452 goes into 4389 9 times with a remainder of 321.
Use 9 as the next digit of our solution. 
Result so far: 183009.0
Subtracting 4068 from 4389 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Step 9:
452 can be fit into 3210 7 times, resulting in a remainder of 46.
The number 7 becomes the next digit in our result. 
Result so far: 183009.7
Subtracting 3164 from 3210 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
When dividing 460 by 452, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 183009.71
Subtracting 452 from 460 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
If we divide 80 by 452, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 183009.71
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
800 divided by 452 is 1 with a remainder of 348.
Use 1 as the next digit of our solution. 
Result so far: 183009.7101
Deduct 452 from 800 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 13:
If we divide 3480 by 452, we get 7 and a remainder of 316.
Put 7 as the next digit of the answer. 
Result so far: 183009.71017
The remainder is 316 after subtracting 3164 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 14:
452 goes into 3160 6 times with a remainder of 448.
Use 6 as the next digit of our solution. 
Result so far: 183009.710176
The remainder is 448 after subtracting 2712 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 15:
The number 452 fits into 4480 9 times, leaving a remainder of 412.
Record the quotient 9 as the next digit in the result. 
Result so far: 183009.7101769
Subtract 4068 from 4480 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 16:
If we divide 4120 by 452, we get 9 and a remainder of 52.
Record the quotient 9 as the next digit in the result. 
Result so far: 183009.71017699
The remainder is 52 after subtracting 4068 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 183009.71017699, and the remainder is 5.2e-08.
