We look at the division of 89416 by 57 
The aim is to understand the frequency of 57 in 89416.

Step 1:
When dividing 8 by 57, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 57

On to step 2:
57 can be fit into 89 1 times, resulting in a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 57 from 89 and we're left with 32.
Append the next digit (4) from the dividend to 32 and continue with: 324 / 57

Step 3:
57 can be fit into 324 5 times, resulting in a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 285 from 324 to get 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 57

Going ahead to step 4:
When dividing 391 by 57, we get 6 with a remainder of 49.
Put 6 as the next digit of the answer. 
Result so far: 156.0
If we take 342 away from 391, we end up with 49.
Fetch the next digit (6) from the dividend, attach it to 49 and continue: 496 / 57

Moving on to step 5:
57 goes into 496 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 1568.0
The remainder is 40 after subtracting 456 from 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 6:
400 divided by 57 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 1568.7
The remainder is 1 after subtracting 399 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
The number 57 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1568.7
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 57 is 1 with a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 1568.701
Deduct 57 from 100 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 9:
430 divided by 57 is 7 with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 1568.7017
If we subtract 399 from 430, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 10:
310 divided by 57 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 1568.70175
If we subtract 285 from 310, we get 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 11:
When dividing 250 by 57, we get 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 1568.701754
If we subtract 228 from 250, we get 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 12:
When dividing 220 by 57, we get 3 with a remainder of 49.
The next digit of our result is 3. 
Result so far: 1568.7017543
If we subtract 171 from 220, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 13:
The number 57 fits into 490 8 times, leaving a remainder of 34.
The next digit of our result is 8. 
Result so far: 1568.70175438
Subtracting 456 from 490 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 1568.70175438 and a remainder of 3.4e-08.
