Let's divide 286217 by 57
The aim is to understand the frequency of 57 in 286217.

Moving on to step 1:
57 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 57

Let's proceed to step 2:
If we divide 28 by 57, we get 0 and a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 57

On to step 3:
When dividing 286 by 57, we get 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 285 from 286 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 57

Going ahead to step 4:
57 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 57

Advancing to step 5:
When dividing 121 by 57, we get 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 502.0
The remainder is 7 after subtracting 114 from 121.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 57

Moving on to step 6:
57 can be fit into 77 1 times, resulting in a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 5021.0
Deduct 57 from 77 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
When dividing 200 by 57, we get 3 with a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 5021.3
The remainder is 29 after subtracting 171 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 8:
290 divided by 57 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 5021.35
If we subtract 285 from 290, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
57 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 5021.35
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
When dividing 500 by 57, we get 8 with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 5021.3508
Deduct 456 from 500 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 11:
The number 57 fits into 440 7 times, leaving a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 5021.35087
Subtracting 399 from 440 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 12:
410 divided by 57 is 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 5021.350877
If we take 399 away from 410, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 5021.350877 and a remainder of 1.1e-06.
