5451315 ÷ 424 
The aim is to understand the frequency of 424 in 5451315.

Advancing to step 1:
The number 424 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 424

Step 2:
424 goes into 54 0 times with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Append the next digit (5) from the dividend to 54 and continue with: 545 / 424

Let's proceed to step 3:
424 goes into 545 1 times with a remainder of 121.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 424 from 545, we get 121.
Take the next digit (1) from the dividend and append it to 121, then repeat: 1211 / 424

Let's proceed to step 4:
If we divide 1211 by 424, we get 2 and a remainder of 363.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 848 from 1211 to get 363.
Include the next digit (3) from the dividend after 363, then repeat: 3633 / 424

Moving on to step 5:
424 can be fit into 3633 8 times, resulting in a remainder of 241.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Subtracting 3392 from 3633 leaves us with 241.
Grab the next digit (1) from the dividend, add it to 241, then carry on: 2411 / 424

On to step 6:
When dividing 2411 by 424, we get 5 with a remainder of 291.
Record the quotient 5 as the next digit in the result. 
Result so far: 1285.0
Subtracting 2120 from 2411 leaves us with 291.
Append the next digit (5) from the dividend to 291 and continue with: 2915 / 424

Advancing to step 7:
2915 divided by 424 is 6 with a remainder of 371.
Write down 6 as next digit of the result. 
Result so far: 12856.0
If we take 2544 away from 2915, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Let's proceed to step 8:
The number 424 fits into 3710 8 times, leaving a remainder of 318.
The next digit of our result is 8. 
Result so far: 12856.8
Deduct 3392 from 3710 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 9:
The number 424 fits into 3180 7 times, leaving a remainder of 212.
Record the quotient 7 as the next digit in the result. 
Result so far: 12856.87
Deduct 2968 from 3180 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 10:
The number 424 fits into 2120 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 12856.875
Deduct 2120 from 2120 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
The number 424 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12856.875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
424 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12856.875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 12856.875, with a leftover of 0.0.
