We're dividing 86707886 by 457 
The aim is to understand the frequency of 457 in 86707886.

Moving on to step 1:
When dividing 8 by 457, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 457

Advancing to step 2:
The number 457 fits into 86 0 times, leaving a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (7) from the dividend after 86, then repeat: 867 / 457

Advancing to step 3:
If we divide 867 by 457, we get 1 and a remainder of 410.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 457 from 867 leaves us with 410.
Bring next digit (0) of the dividend behind the 410 and repeat the process: 4100 / 457

Advancing to step 4:
457 can be fit into 4100 8 times, resulting in a remainder of 444.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 3656 from 4100 leaves us with 444.
Grab the next digit (7) from the dividend, add it to 444, then carry on: 4447 / 457

On to step 5:
457 can be fit into 4447 9 times, resulting in a remainder of 334.
Write down 9 as next digit of the result. 
Result so far: 189.0
If we take 4113 away from 4447, we end up with 334.
Take the next digit (8) from the dividend and append it to 334, then repeat: 3348 / 457

Going ahead to step 6:
3348 divided by 457 is 7 with a remainder of 149.
Put 7 as the next digit of the answer. 
Result so far: 1897.0
The remainder is 149 after subtracting 3199 from 3348.
Bring next digit (8) of the dividend behind the 149 and repeat the process: 1498 / 457

On to step 7:
457 can be fit into 1498 3 times, resulting in a remainder of 127.
Record the quotient 3 as the next digit in the result. 
Result so far: 18973.0
Subtracting 1371 from 1498 leaves us with 127.
Bring next digit (6) of the dividend behind the 127 and repeat the process: 1276 / 457

Advancing to step 8:
457 goes into 1276 2 times with a remainder of 362.
The next digit of our result is 2. 
Result so far: 189732.0
Subtract 914 from 1276 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Going ahead to step 9:
If we divide 3620 by 457, we get 7 and a remainder of 421.
The number 7 becomes the next digit in our result. 
Result so far: 189732.7
If we subtract 3199 from 3620, we get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Going ahead to step 10:
457 goes into 4210 9 times with a remainder of 97.
Put 9 as the next digit of the answer. 
Result so far: 189732.79
Subtract 4113 from 4210 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 11:
When dividing 970 by 457, we get 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 189732.792
Subtracting 914 from 970 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
560 divided by 457 is 1 with a remainder of 103.
The number 1 becomes the next digit in our result. 
Result so far: 189732.7921
The remainder is 103 after subtracting 457 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 13:
457 goes into 1030 2 times with a remainder of 116.
Use 2 as the next digit of our solution. 
Result so far: 189732.79212
Deduct 914 from 1030 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 14:
1160 divided by 457 is 2 with a remainder of 246.
The next digit of our result is 2. 
Result so far: 189732.792122
If we subtract 914 from 1160, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

In conclusion, the division gives 189732.792122 with a balance of 2.46e-05.
