We look at the division of 40878101 by 452 
The aim is to understand the frequency of 452 in 40878101.

Step 1:
4 divided by 452 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 452

Step 2:
452 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 452

Advancing to step 3:
452 can be fit into 408 0 times, resulting in a remainder of 408.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 408 to get 408.
Fetch the next digit (7) from the dividend, attach it to 408 and continue: 4087 / 452

Let's proceed to step 4:
The number 452 fits into 4087 9 times, leaving a remainder of 19.
The next digit of our result is 9. 
Result so far: 9.0
If we take 4068 away from 4087, we end up with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 452

On to step 5:
If we divide 198 by 452, we get 0 and a remainder of 198.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Deduct 0 from 198 and we're left with 198.
Grab the next digit (1) from the dividend, add it to 198, then carry on: 1981 / 452

Step 6:
When dividing 1981 by 452, we get 4 with a remainder of 173.
Record the quotient 4 as the next digit in the result. 
Result so far: 904.0
Deduct 1808 from 1981 and we're left with 173.
Grab the next digit (0) from the dividend, add it to 173, then carry on: 1730 / 452

Going ahead to step 7:
452 can be fit into 1730 3 times, resulting in a remainder of 374.
Record the quotient 3 as the next digit in the result. 
Result so far: 9043.0
The remainder is 374 after subtracting 1356 from 1730.
Append the next digit (1) from the dividend to 374 and continue with: 3741 / 452

Let's proceed to step 8:
452 goes into 3741 8 times with a remainder of 125.
Put 8 as the next digit of the answer. 
Result so far: 90438.0
If we subtract 3616 from 3741, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 9:
452 can be fit into 1250 2 times, resulting in a remainder of 346.
Put 2 as the next digit of the answer. 
Result so far: 90438.2
Deduct 904 from 1250 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Moving on to step 10:
452 goes into 3460 7 times with a remainder of 296.
Put 7 as the next digit of the answer. 
Result so far: 90438.27
The remainder is 296 after subtracting 3164 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 11:
The number 452 fits into 2960 6 times, leaving a remainder of 248.
Put 6 as the next digit of the answer. 
Result so far: 90438.276
If we subtract 2712 from 2960, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 12:
If we divide 2480 by 452, we get 5 and a remainder of 220.
The next digit of our result is 5. 
Result so far: 90438.2765
If we take 2260 away from 2480, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 13:
The number 452 fits into 2200 4 times, leaving a remainder of 392.
The next digit of our result is 4. 
Result so far: 90438.27654
Deduct 1808 from 2200 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 14:
3920 divided by 452 is 8 with a remainder of 304.
The number 8 becomes the next digit in our result. 
Result so far: 90438.276548
If we take 3616 away from 3920, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 15:
When dividing 3040 by 452, we get 6 with a remainder of 328.
The number 6 becomes the next digit in our result. 
Result so far: 90438.2765486
Subtracting 2712 from 3040 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 16:
When dividing 3280 by 452, we get 7 with a remainder of 116.
Write down 7 as next digit of the result. 
Result so far: 90438.27654867
The remainder is 116 after subtracting 3164 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The quotient of the division is 90438.27654867, and the remainder is 1.16e-07.
