Let's divide 98957581 by 457
The aim is to understand the frequency of 457 in 98957581.

On to step 1:
457 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 457

On to step 2:
457 goes into 98 0 times with a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Append the next digit (9) from the dividend to 98 and continue with: 989 / 457

Going ahead to step 3:
If we divide 989 by 457, we get 2 and a remainder of 75.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 75 after subtracting 914 from 989.
Include the next digit (5) from the dividend after 75, then repeat: 755 / 457

Advancing to step 4:
If we divide 755 by 457, we get 1 and a remainder of 298.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 457 from 755 to get 298.
Take the next digit (7) from the dividend and append it to 298, then repeat: 2987 / 457

Moving on to step 5:
The number 457 fits into 2987 6 times, leaving a remainder of 245.
Write down 6 as next digit of the result. 
Result so far: 216.0
Subtract 2742 from 2987 to get 245.
Append the next digit (5) from the dividend to 245 and continue with: 2455 / 457

Step 6:
The number 457 fits into 2455 5 times, leaving a remainder of 170.
The next digit of our result is 5. 
Result so far: 2165.0
Deduct 2285 from 2455 and we're left with 170.
Bring next digit (8) of the dividend behind the 170 and repeat the process: 1708 / 457

Moving on to step 7:
457 goes into 1708 3 times with a remainder of 337.
Put 3 as the next digit of the answer. 
Result so far: 21653.0
If we subtract 1371 from 1708, we get 337.
Bring next digit (1) of the dividend behind the 337 and repeat the process: 3371 / 457

Step 8:
457 goes into 3371 7 times with a remainder of 172.
The number 7 becomes the next digit in our result. 
Result so far: 216537.0
If we take 3199 away from 3371, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 9:
If we divide 1720 by 457, we get 3 and a remainder of 349.
Put 3 as the next digit of the answer. 
Result so far: 216537.3
Subtract 1371 from 1720 to get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Moving on to step 10:
457 can be fit into 3490 7 times, resulting in a remainder of 291.
Put 7 as the next digit of the answer. 
Result so far: 216537.37
Subtracting 3199 from 3490 leaves us with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

On to step 11:
457 goes into 2910 6 times with a remainder of 168.
The next digit of our result is 6. 
Result so far: 216537.376
If we take 2742 away from 2910, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 12:
The number 457 fits into 1680 3 times, leaving a remainder of 309.
Use 3 as the next digit of our solution. 
Result so far: 216537.3763
If we take 1371 away from 1680, we end up with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Let's proceed to step 13:
457 can be fit into 3090 6 times, resulting in a remainder of 348.
The number 6 becomes the next digit in our result. 
Result so far: 216537.37636
If we take 2742 away from 3090, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 14:
If we divide 3480 by 457, we get 7 and a remainder of 281.
The next digit of our result is 7. 
Result so far: 216537.376367
If we take 3199 away from 3480, we end up with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Advancing to step 15:
457 can be fit into 2810 6 times, resulting in a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 216537.3763676
If we take 2742 away from 2810, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 16:
680 divided by 457 is 1 with a remainder of 223.
Record the quotient 1 as the next digit in the result. 
Result so far: 216537.37636761
If we take 457 away from 680, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

The final result is 216537.37636761 with a remainder of 2.23e-07.
