57577358 divided by 688 
The aim is to understand the frequency of 688 in 57577358.

Let's proceed to step 1:
If we divide 5 by 688, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 688

Let's proceed to step 2:
The number 688 fits into 57 0 times, leaving a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Bring next digit (5) of the dividend behind the 57 and repeat the process: 575 / 688

Moving on to step 3:
688 goes into 575 0 times with a remainder of 575.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 575 leaves us with 575.
Include the next digit (7) from the dividend after 575, then repeat: 5757 / 688

Moving on to step 4:
688 can be fit into 5757 8 times, resulting in a remainder of 253.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 253 after subtracting 5504 from 5757.
Take the next digit (7) from the dividend and append it to 253, then repeat: 2537 / 688

Let's proceed to step 5:
688 goes into 2537 3 times with a remainder of 473.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Subtracting 2064 from 2537 leaves us with 473.
Append the next digit (3) from the dividend to 473 and continue with: 4733 / 688

On to step 6:
688 goes into 4733 6 times with a remainder of 605.
Put 6 as the next digit of the answer. 
Result so far: 836.0
Subtracting 4128 from 4733 leaves us with 605.
Fetch the next digit (5) from the dividend, attach it to 605 and continue: 6055 / 688

Step 7:
688 can be fit into 6055 8 times, resulting in a remainder of 551.
The next digit of our result is 8. 
Result so far: 8368.0
If we subtract 5504 from 6055, we get 551.
Append the next digit (8) from the dividend to 551 and continue with: 5518 / 688

On to step 8:
688 goes into 5518 8 times with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 83688.0
If we subtract 5504 from 5518, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
If we divide 140 by 688, we get 0 and a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 83688.0
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 10:
1400 divided by 688 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 83688.02
The remainder is 24 after subtracting 1376 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
688 goes into 240 0 times with a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 83688.02
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 12:
2400 divided by 688 is 3 with a remainder of 336.
Write down 3 as next digit of the result. 
Result so far: 83688.0203
If we take 2064 away from 2400, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 13:
3360 divided by 688 is 4 with a remainder of 608.
The next digit of our result is 4. 
Result so far: 83688.02034
Subtract 2752 from 3360 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Going ahead to step 14:
If we divide 6080 by 688, we get 8 and a remainder of 576.
The next digit of our result is 8. 
Result so far: 83688.020348
The remainder is 576 after subtracting 5504 from 6080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Going ahead to step 15:
The number 688 fits into 5760 8 times, leaving a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 83688.0203488
Subtract 5504 from 5760 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final outcome is 83688.0203488, with a leftover of 2.56e-06.
