We're dividing 48387579 by 451 
The aim is to understand the frequency of 451 in 48387579.

Going ahead to step 1:
If we divide 4 by 451, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 451

Advancing to step 2:
When dividing 48 by 451, we get 0 with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Include the next digit (3) from the dividend after 48, then repeat: 483 / 451

Moving on to step 3:
If we divide 483 by 451, we get 1 and a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 32 after subtracting 451 from 483.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 451

Moving on to step 4:
328 divided by 451 is 0 with a remainder of 328.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 328, we end up with 328.
Fetch the next digit (7) from the dividend, attach it to 328 and continue: 3287 / 451

Going ahead to step 5:
The number 451 fits into 3287 7 times, leaving a remainder of 130.
Write down 7 as next digit of the result. 
Result so far: 107.0
The remainder is 130 after subtracting 3157 from 3287.
Append the next digit (5) from the dividend to 130 and continue with: 1305 / 451

Step 6:
1305 divided by 451 is 2 with a remainder of 403.
The next digit of our result is 2. 
Result so far: 1072.0
If we take 902 away from 1305, we end up with 403.
Append the next digit (7) from the dividend to 403 and continue with: 4037 / 451

Step 7:
If we divide 4037 by 451, we get 8 and a remainder of 429.
Put 8 as the next digit of the answer. 
Result so far: 10728.0
The remainder is 429 after subtracting 3608 from 4037.
Grab the next digit (9) from the dividend, add it to 429, then carry on: 4299 / 451

Going ahead to step 8:
If we divide 4299 by 451, we get 9 and a remainder of 240.
The next digit of our result is 9. 
Result so far: 107289.0
If we subtract 4059 from 4299, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 9:
451 goes into 2400 5 times with a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 107289.5
Subtract 2255 from 2400 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 10:
If we divide 1450 by 451, we get 3 and a remainder of 97.
The number 3 becomes the next digit in our result. 
Result so far: 107289.53
If we take 1353 away from 1450, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 11:
970 divided by 451 is 2 with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 107289.532
The remainder is 68 after subtracting 902 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
If we divide 680 by 451, we get 1 and a remainder of 229.
The next digit of our result is 1. 
Result so far: 107289.5321
The remainder is 229 after subtracting 451 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Going ahead to step 13:
451 can be fit into 2290 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 107289.53215
Subtract 2255 from 2290 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
The number 451 fits into 350 0 times, leaving a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 107289.53215
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 15:
3500 divided by 451 is 7 with a remainder of 343.
The number 7 becomes the next digit in our result. 
Result so far: 107289.5321507
If we subtract 3157 from 3500, we get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Let's proceed to step 16:
451 goes into 3430 7 times with a remainder of 273.
The next digit of our result is 7. 
Result so far: 107289.53215077
If we subtract 3157 from 3430, we get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

The final result is 107289.53215077 with a remainder of 2.73e-07.
