Let's divide 688449 by 57
The aim is to understand the frequency of 57 in 688449.

Step 1:
If we divide 6 by 57, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 57

On to step 2:
57 can be fit into 68 1 times, resulting in a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 57 from 68 and we're left with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 57

Moving on to step 3:
The number 57 fits into 118 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 114 away from 118, we end up with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 57

Moving on to step 4:
44 divided by 57 is 0 with a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 120.0
If we subtract 0 from 44, we get 44.
Include the next digit (4) from the dividend after 44, then repeat: 444 / 57

Going ahead to step 5:
When dividing 444 by 57, we get 7 with a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 1207.0
Subtract 399 from 444 to get 45.
Fetch the next digit (9) from the dividend, attach it to 45 and continue: 459 / 57

On to step 6:
The number 57 fits into 459 8 times, leaving a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 12078.0
Subtract 456 from 459 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
When dividing 30 by 57, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 12078.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
57 can be fit into 300 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 12078.05
Deduct 285 from 300 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
150 divided by 57 is 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 12078.052
Subtracting 114 from 150 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
57 goes into 360 6 times with a remainder of 18.
The next digit of our result is 6. 
Result so far: 12078.0526
Deduct 342 from 360 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
180 divided by 57 is 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 12078.05263
Subtracting 171 from 180 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
If we divide 90 by 57, we get 1 and a remainder of 33.
The next digit of our result is 1. 
Result so far: 12078.052631
Deduct 57 from 90 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 13:
If we divide 330 by 57, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 12078.0526315
The remainder is 45 after subtracting 285 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 14:
57 can be fit into 450 7 times, resulting in a remainder of 51.
The next digit of our result is 7. 
Result so far: 12078.05263157
The remainder is 51 after subtracting 399 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 12078.05263157 and a remainder of 5.1e-08.
