Let's divide 86170652 by 457
The aim is to understand the frequency of 457 in 86170652.

On to step 1:
457 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 457

Step 2:
457 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Take the next digit (1) from the dividend and append it to 86, then repeat: 861 / 457

Going ahead to step 3:
The number 457 fits into 861 1 times, leaving a remainder of 404.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 457 from 861 leaves us with 404.
Append the next digit (7) from the dividend to 404 and continue with: 4047 / 457

Step 4:
When dividing 4047 by 457, we get 8 with a remainder of 391.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 3656 from 4047 and we're left with 391.
Grab the next digit (0) from the dividend, add it to 391, then carry on: 3910 / 457

Advancing to step 5:
457 goes into 3910 8 times with a remainder of 254.
The next digit of our result is 8. 
Result so far: 188.0
If we subtract 3656 from 3910, we get 254.
Append the next digit (6) from the dividend to 254 and continue with: 2546 / 457

On to step 6:
457 can be fit into 2546 5 times, resulting in a remainder of 261.
Put 5 as the next digit of the answer. 
Result so far: 1885.0
Subtract 2285 from 2546 to get 261.
Grab the next digit (5) from the dividend, add it to 261, then carry on: 2615 / 457

Advancing to step 7:
457 goes into 2615 5 times with a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 18855.0
Deduct 2285 from 2615 and we're left with 330.
Take the next digit (2) from the dividend and append it to 330, then repeat: 3302 / 457

Step 8:
457 can be fit into 3302 7 times, resulting in a remainder of 103.
Put 7 as the next digit of the answer. 
Result so far: 188557.0
If we take 3199 away from 3302, we end up with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 9:
The number 457 fits into 1030 2 times, leaving a remainder of 116.
The number 2 becomes the next digit in our result. 
Result so far: 188557.2
If we take 914 away from 1030, we end up 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.

Let's proceed to step 10:
457 can be fit into 1160 2 times, resulting in a remainder of 246.
Use 2 as the next digit of our solution. 
Result so far: 188557.22
Deduct 914 from 1160 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

After the division, we end up with 188557.22 and a remainder of 0.246.
