We look at the division of 40857689 by 688 
We're looking to find how many times 688 goes into 40857689.

Moving on to step 1:
If we divide 4 by 688, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 688

On to step 2:
40 divided by 688 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 688

On to step 3:
The number 688 fits into 408 0 times, leaving a remainder of 408.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 408, we get 408.
Take the next digit (5) from the dividend and append it to 408, then repeat: 4085 / 688

Let's proceed to step 4:
When dividing 4085 by 688, we get 5 with a remainder of 645.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 3440 from 4085 and we're left with 645.
Append the next digit (7) from the dividend to 645 and continue with: 6457 / 688

Step 5:
The number 688 fits into 6457 9 times, leaving a remainder of 265.
Use 9 as the next digit of our solution. 
Result so far: 59.0
The remainder is 265 after subtracting 6192 from 6457.
Fetch the next digit (6) from the dividend, attach it to 265 and continue: 2656 / 688

On to step 6:
688 can be fit into 2656 3 times, resulting in a remainder of 592.
The number 3 becomes the next digit in our result. 
Result so far: 593.0
If we take 2064 away from 2656, we end up with 592.
Include the next digit (8) from the dividend after 592, then repeat: 5928 / 688

Moving on to step 7:
688 goes into 5928 8 times with a remainder of 424.
The next digit of our result is 8. 
Result so far: 5938.0
Deduct 5504 from 5928 and we're left with 424.
Take the next digit (9) from the dividend and append it to 424, then repeat: 4249 / 688

Moving on to step 8:
When dividing 4249 by 688, we get 6 with a remainder of 121.
Write down 6 as next digit of the result. 
Result so far: 59386.0
The remainder is 121 after subtracting 4128 from 4249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 9:
688 can be fit into 1210 1 times, resulting in a remainder of 522.
Put 1 as the next digit of the answer. 
Result so far: 59386.1
If we take 688 away from 1210, we end up with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Advancing to step 10:
5220 divided by 688 is 7 with a remainder of 404.
Record the quotient 7 as the next digit in the result. 
Result so far: 59386.17
If we take 4816 away from 5220, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 11:
When dividing 4040 by 688, we get 5 with a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 59386.175
If we take 3440 away from 4040, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 12:
If we divide 6000 by 688, we get 8 and a remainder of 496.
The number 8 becomes the next digit in our result. 
Result so far: 59386.1758
Subtract 5504 from 6000 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 13:
688 goes into 4960 7 times with a remainder of 144.
Put 7 as the next digit of the answer. 
Result so far: 59386.17587
If we take 4816 away from 4960, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 14:
If we divide 1440 by 688, we get 2 and a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 59386.175872
Subtracting 1376 from 1440 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 15:
688 goes into 640 0 times with a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 59386.175872
The remainder is 640 after subtracting 0 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 16:
688 goes into 6400 9 times with a remainder of 208.
Write down 9 as next digit of the result. 
Result so far: 59386.17587209
If we take 6192 away from 6400, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Our division results in 59386.17587209 with a remaining 2.08e-07.
