We look at the division of 31578659 by 454 
The aim is to understand the frequency of 454 in 31578659.

Going ahead to step 1:
If we divide 3 by 454, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 454

Step 2:
The number 454 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 454

Going ahead to step 3:
If we divide 315 by 454, we get 0 and a remainder of 315.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 315 and we're left with 315.
Grab the next digit (7) from the dividend, add it to 315, then carry on: 3157 / 454

Moving on to step 4:
If we divide 3157 by 454, we get 6 and a remainder of 433.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 2724 from 3157 leaves us with 433.
Take the next digit (8) from the dividend and append it to 433, then repeat: 4338 / 454

Moving on to step 5:
454 can be fit into 4338 9 times, resulting in a remainder of 252.
Use 9 as the next digit of our solution. 
Result so far: 69.0
Subtracting 4086 from 4338 leaves us with 252.
Append the next digit (6) from the dividend to 252 and continue with: 2526 / 454

Step 6:
2526 divided by 454 is 5 with a remainder of 256.
Use 5 as the next digit of our solution. 
Result so far: 695.0
The remainder is 256 after subtracting 2270 from 2526.
Append the next digit (5) from the dividend to 256 and continue with: 2565 / 454

Step 7:
454 can be fit into 2565 5 times, resulting in a remainder of 295.
Write down 5 as next digit of the result. 
Result so far: 6955.0
The remainder is 295 after subtracting 2270 from 2565.
Take the next digit (9) from the dividend and append it to 295, then repeat: 2959 / 454

Moving on to step 8:
If we divide 2959 by 454, we get 6 and a remainder of 235.
Record the quotient 6 as the next digit in the result. 
Result so far: 69556.0
Deduct 2724 from 2959 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 9:
454 goes into 2350 5 times with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 69556.5
Subtracting 2270 from 2350 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
454 goes into 800 1 times with a remainder of 346.
Write down 1 as next digit of the result. 
Result so far: 69556.51
Subtracting 454 from 800 leaves us 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.

On to step 11:
3460 divided by 454 is 7 with a remainder of 282.
The next digit of our result is 7. 
Result so far: 69556.517
The remainder is 282 after subtracting 3178 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Let's proceed to step 12:
454 goes into 2820 6 times with a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 69556.5176
The remainder is 96 after subtracting 2724 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 13:
454 goes into 960 2 times with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 69556.51762
If we take 908 away from 960, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 14:
If we divide 520 by 454, we get 1 and a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 69556.517621
Subtract 454 from 520 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 15:
660 divided by 454 is 1 with a remainder of 206.
Put 1 as the next digit of the answer. 
Result so far: 69556.5176211
Subtracting 454 from 660 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

In conclusion, the division gives 69556.5176211 with a balance of 2.06e-06.
