52350503 ÷ 454 
The aim is to understand the frequency of 454 in 52350503.

Advancing to step 1:
If we divide 5 by 454, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 454

On to step 2:
When dividing 52 by 454, we get 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Grab the next digit (3) from the dividend, add it to 52, then carry on: 523 / 454

Advancing to step 3:
The number 454 fits into 523 1 times, leaving a remainder of 69.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 69 after subtracting 454 from 523.
Append the next digit (5) from the dividend to 69 and continue with: 695 / 454

Let's proceed to step 4:
454 goes into 695 1 times with a remainder of 241.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 454 from 695 to get 241.
Append the next digit (0) from the dividend to 241 and continue with: 2410 / 454

Advancing to step 5:
2410 divided by 454 is 5 with a remainder of 140.
Put 5 as the next digit of the answer. 
Result so far: 115.0
The remainder is 140 after subtracting 2270 from 2410.
Fetch the next digit (5) from the dividend, attach it to 140 and continue: 1405 / 454

Advancing to step 6:
454 can be fit into 1405 3 times, resulting in a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 1153.0
If we take 1362 away from 1405, we end up with 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 454

Let's proceed to step 7:
When dividing 430 by 454, we get 0 with a remainder of 430.
Record the quotient 0 as the next digit in the result. 
Result so far: 11530.0
The remainder is 430 after subtracting 0 from 430.
Fetch the next digit (3) from the dividend, attach it to 430 and continue: 4303 / 454

Going ahead to step 8:
4303 divided by 454 is 9 with a remainder of 217.
Record the quotient 9 as the next digit in the result. 
Result so far: 115309.0
Subtracting 4086 from 4303 leaves us with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Step 9:
The number 454 fits into 2170 4 times, leaving a remainder of 354.
The next digit of our result is 4. 
Result so far: 115309.4
If we take 1816 away from 2170, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

On to step 10:
When dividing 3540 by 454, we get 7 with a remainder of 362.
The next digit of our result is 7. 
Result so far: 115309.47
Deduct 3178 from 3540 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 11:
When dividing 3620 by 454, we get 7 with a remainder of 442.
Use 7 as the next digit of our solution. 
Result so far: 115309.477
Deduct 3178 from 3620 and we're left with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

After the division, we end up with 115309.477 and a remainder of 0.0442.
