68516 ÷ 57 
The aim is to understand the frequency of 57 in 68516.

Advancing to step 1:
The number 57 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 57

Advancing to step 2:
57 goes into 68 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 57 from 68 to get 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 57

Moving on to step 3:
The number 57 fits into 115 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 114 from 115, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 57

Moving on to step 4:
11 divided by 57 is 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
Subtract 0 from 11 to get 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 57

Moving on to step 5:
The number 57 fits into 116 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 1202.0
If we take 114 away from 116, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 6:
If we divide 20 by 57, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1202.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
57 can be fit into 200 3 times, resulting in a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 1202.03
If we take 171 away from 200, we end up with 29.
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.
Put 5 as the next digit of the answer. 
Result so far: 1202.035
Subtract 285 from 290 to 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.

Let's proceed to step 9:
When dividing 50 by 57, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 1202.035
Deduct 0 from 50 and we're left 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.

Advancing to step 10:
If we divide 500 by 57, we get 8 and a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 1202.03508
Subtracting 456 from 500 leaves us 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:
If we divide 440 by 57, we get 7 and a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 1202.035087
Subtract 399 from 440 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 12:
When dividing 410 by 57, we get 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 1202.0350877
Subtract 399 from 410 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 1202.0350877 with a remaining 1.1e-07.
