Let's divide 486577 by 57
The aim is to understand the frequency of 57 in 486577.

Step 1:
The number 57 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 57

Step 2:
When dividing 48 by 57, we get 0 with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Grab the next digit (6) from the dividend, add it to 48, then carry on: 486 / 57

Moving on to step 3:
57 goes into 486 8 times with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 456 from 486 and we're left with 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 57

On to step 4:
57 goes into 305 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 85.0
If we take 285 away from 305, we end up with 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 57

Step 5:
If we divide 207 by 57, we get 3 and a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 853.0
If we subtract 171 from 207, we get 36.
Fetch the next digit (7) from the dividend, attach it to 36 and continue: 367 / 57

Moving on to step 6:
367 divided by 57 is 6 with a remainder of 25.
The next digit of our result is 6. 
Result so far: 8536.0
Subtracting 342 from 367 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
57 can be fit into 250 4 times, resulting in a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 8536.4
Subtracting 228 from 250 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
If we divide 220 by 57, we get 3 and a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 8536.43
Subtracting 171 from 220 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
57 goes into 490 8 times with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 8536.438
If we subtract 456 from 490, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
The number 57 fits into 340 5 times, leaving a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 8536.4385
Subtracting 285 from 340 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 11:
550 divided by 57 is 9 with a remainder of 37.
The next digit of our result is 9. 
Result so far: 8536.43859
If we subtract 513 from 550, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 12:
57 goes into 370 6 times with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 8536.438596
If we subtract 342 from 370, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 13:
The number 57 fits into 280 4 times, leaving a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 8536.4385964
If we take 228 away from 280, 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:
520 divided by 57 is 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 8536.43859649
If we take 513 away from 520, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 8536.43859649, with a leftover of 7e-09.
