We look at the division of 69363188 by 453 
The aim is to understand the frequency of 453 in 69363188.

Step 1:
6 divided by 453 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 453

Let's proceed to step 2:
453 can be fit into 69 0 times, resulting in a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Append the next digit (3) from the dividend to 69 and continue with: 693 / 453

Step 3:
When dividing 693 by 453, we get 1 with a remainder of 240.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 453 from 693, we get 240.
Bring next digit (6) of the dividend behind the 240 and repeat the process: 2406 / 453

Moving on to step 4:
The number 453 fits into 2406 5 times, leaving a remainder of 141.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 141 after subtracting 2265 from 2406.
Grab the next digit (3) from the dividend, add it to 141, then carry on: 1413 / 453

Let's proceed to step 5:
When dividing 1413 by 453, we get 3 with a remainder of 54.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
Subtract 1359 from 1413 to get 54.
Append the next digit (1) from the dividend to 54 and continue with: 541 / 453

On to step 6:
The number 453 fits into 541 1 times, leaving a remainder of 88.
The number 1 becomes the next digit in our result. 
Result so far: 1531.0
If we subtract 453 from 541, we get 88.
Take the next digit (8) from the dividend and append it to 88, then repeat: 888 / 453

Moving on to step 7:
If we divide 888 by 453, we get 1 and a remainder of 435.
Record the quotient 1 as the next digit in the result. 
Result so far: 15311.0
The remainder is 435 after subtracting 453 from 888.
Bring next digit (8) of the dividend behind the 435 and repeat the process: 4358 / 453

Moving on to step 8:
453 can be fit into 4358 9 times, resulting in a remainder of 281.
Put 9 as the next digit of the answer. 
Result so far: 153119.0
If we subtract 4077 from 4358, we get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Going ahead to step 9:
453 goes into 2810 6 times with a remainder of 92.
The number 6 becomes the next digit in our result. 
Result so far: 153119.6
Deduct 2718 from 2810 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 10:
If we divide 920 by 453, we get 2 and a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 153119.62
If we take 906 away from 920, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
140 divided by 453 is 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 153119.62
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
When dividing 1400 by 453, we get 3 with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 153119.6203
If we subtract 1359 from 1400, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 13:
If we divide 410 by 453, we get 0 and a remainder of 410.
Record the quotient 0 as the next digit in the result. 
Result so far: 153119.6203
Subtract 0 from 410 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 14:
4100 divided by 453 is 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 153119.620309
The remainder is 23 after subtracting 4077 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 15:
When dividing 230 by 453, we get 0 with a remainder of 230.
The next digit of our result is 0. 
Result so far: 153119.620309
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 16:
When dividing 2300 by 453, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 153119.62030905
The remainder is 35 after subtracting 2265 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 153119.62030905, with a leftover of 3.5e-08.
