Let's divide 64615869 by 688
We want to divide 64615869 by 688.

Advancing to step 1:
688 can be fit into 6 0 times, resulting in 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.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 688

Step 2:
When dividing 64 by 688, we get 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Grab the next digit (6) from the dividend, add it to 64, then carry on: 646 / 688

Advancing to step 3:
If we divide 646 by 688, we get 0 and a remainder of 646.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 646 and we're left with 646.
Append the next digit (1) from the dividend to 646 and continue with: 6461 / 688

Moving on to step 4:
The number 688 fits into 6461 9 times, leaving a remainder of 269.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 6192 from 6461, we get 269.
Include the next digit (5) from the dividend after 269, then repeat: 2695 / 688

On to step 5:
If we divide 2695 by 688, we get 3 and a remainder of 631.
Use 3 as the next digit of our solution. 
Result so far: 93.0
If we subtract 2064 from 2695, we get 631.
Take the next digit (8) from the dividend and append it to 631, then repeat: 6318 / 688

Let's proceed to step 6:
6318 divided by 688 is 9 with a remainder of 126.
The next digit of our result is 9. 
Result so far: 939.0
Deduct 6192 from 6318 and we're left with 126.
Bring next digit (6) of the dividend behind the 126 and repeat the process: 1266 / 688

Let's proceed to step 7:
1266 divided by 688 is 1 with a remainder of 578.
Write down 1 as next digit of the result. 
Result so far: 9391.0
Deduct 688 from 1266 and we're left with 578.
Bring next digit (9) of the dividend behind the 578 and repeat the process: 5789 / 688

Step 8:
When dividing 5789 by 688, we get 8 with a remainder of 285.
The number 8 becomes the next digit in our result. 
Result so far: 93918.0
Subtracting 5504 from 5789 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 9:
If we divide 2850 by 688, we get 4 and a remainder of 98.
Put 4 as the next digit of the answer. 
Result so far: 93918.4
The remainder is 98 after subtracting 2752 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 10:
688 can be fit into 980 1 times, resulting in a remainder of 292.
Use 1 as the next digit of our solution. 
Result so far: 93918.41
Subtract 688 from 980 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 11:
688 goes into 2920 4 times with a remainder of 168.
The number 4 becomes the next digit in our result. 
Result so far: 93918.414
Subtract 2752 from 2920 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 12:
If we divide 1680 by 688, we get 2 and a remainder of 304.
Write down 2 as next digit of the result. 
Result so far: 93918.4142
Deduct 1376 from 1680 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 13:
The number 688 fits into 3040 4 times, leaving a remainder of 288.
The next digit of our result is 4. 
Result so far: 93918.41424
If we subtract 2752 from 3040, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 14:
The number 688 fits into 2880 4 times, leaving a remainder of 128.
Use 4 as the next digit of our solution. 
Result so far: 93918.414244
Subtracting 2752 from 2880 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

In conclusion, the division gives 93918.414244 with a balance of 1.28e-05.
