We look at the division of 31262963 by 454 
The aim is to understand the frequency of 454 in 31262963.

Going ahead to step 1:
The number 454 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 454

On to step 2:
If we divide 31 by 454, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 454

Moving on to step 3:
454 can be fit into 312 0 times, resulting in a remainder of 312.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 312 to get 312.
Grab the next digit (6) from the dividend, add it to 312, then carry on: 3126 / 454

Going ahead to step 4:
3126 divided by 454 is 6 with a remainder of 402.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 402 after subtracting 2724 from 3126.
Take the next digit (2) from the dividend and append it to 402, then repeat: 4022 / 454

Advancing to step 5:
If we divide 4022 by 454, we get 8 and a remainder of 390.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
The remainder is 390 after subtracting 3632 from 4022.
Take the next digit (9) from the dividend and append it to 390, then repeat: 3909 / 454

Step 6:
The number 454 fits into 3909 8 times, leaving a remainder of 277.
The next digit of our result is 8. 
Result so far: 688.0
Deduct 3632 from 3909 and we're left with 277.
Take the next digit (6) from the dividend and append it to 277, then repeat: 2776 / 454

Moving on to step 7:
454 goes into 2776 6 times with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 6886.0
Deduct 2724 from 2776 and we're left with 52.
Bring next digit (3) of the dividend behind the 52 and repeat the process: 523 / 454

Moving on to step 8:
The number 454 fits into 523 1 times, leaving a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 68861.0
The remainder is 69 after subtracting 454 from 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
454 goes into 690 1 times with a remainder of 236.
Use 1 as the next digit of our solution. 
Result so far: 68861.1
If we take 454 away from 690, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 10:
When dividing 2360 by 454, we get 5 with a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 68861.15
The remainder is 90 after subtracting 2270 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 11:
900 divided by 454 is 1 with a remainder of 446.
The number 1 becomes the next digit in our result. 
Result so far: 68861.151
If we subtract 454 from 900, we get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

On to step 12:
454 goes into 4460 9 times with a remainder of 374.
Write down 9 as next digit of the result. 
Result so far: 68861.1519
The remainder is 374 after subtracting 4086 from 4460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Let's proceed to step 13:
When dividing 3740 by 454, we get 8 with a remainder of 108.
The next digit of our result is 8. 
Result so far: 68861.15198
Deduct 3632 from 3740 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 14:
454 can be fit into 1080 2 times, resulting in a remainder of 172.
The next digit of our result is 2. 
Result so far: 68861.151982
If we subtract 908 from 1080, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 15:
1720 divided by 454 is 3 with a remainder of 358.
Write down 3 as next digit of the result. 
Result so far: 68861.1519823
If we subtract 1362 from 1720, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 16:
3580 divided by 454 is 7 with a remainder of 402.
The next digit of our result is 7. 
Result so far: 68861.15198237
The remainder is 402 after subtracting 3178 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

The final outcome is 68861.15198237, with a leftover of 4.02e-07.
