29102495 ÷ 688 
Let's see how many times 688 fits into 29102495.

Step 1:
688 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 688

Step 2:
29 divided by 688 is 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 688

Step 3:
688 goes into 291 0 times with a remainder of 291.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 291 after subtracting 0 from 291.
Include the next digit (0) from the dividend after 291, then repeat: 2910 / 688

Moving on to step 4:
688 goes into 2910 4 times with a remainder of 158.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 2752 from 2910 to get 158.
Append the next digit (2) from the dividend to 158 and continue with: 1582 / 688

Going ahead to step 5:
If we divide 1582 by 688, we get 2 and a remainder of 206.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we subtract 1376 from 1582, we get 206.
Append the next digit (4) from the dividend to 206 and continue with: 2064 / 688

Advancing to step 6:
If we divide 2064 by 688, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 423.0
If we take 2064 away from 2064, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 688

Going ahead to step 7:
688 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 4230.0
If we subtract 0 from 9, we get 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 688

Advancing to step 8:
688 can be fit into 95 0 times, resulting in a remainder of 95.
The next digit of our result is 0. 
Result so far: 42300.0
Subtract 0 from 95 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 9:
When dividing 950 by 688, we get 1 with a remainder of 262.
Use 1 as the next digit of our solution. 
Result so far: 42300.1
Deduct 688 from 950 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 10:
2620 divided by 688 is 3 with a remainder of 556.
Write down 3 as next digit of the result. 
Result so far: 42300.13
Deduct 2064 from 2620 and we're left with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Moving on to step 11:
688 goes into 5560 8 times with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 42300.138
If we take 5504 away from 5560, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 12:
When dividing 560 by 688, we get 0 with a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 42300.138
If we subtract 0 from 560, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 13:
688 goes into 5600 8 times with a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 42300.13808
Deduct 5504 from 5600 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 14:
When dividing 960 by 688, we get 1 with a remainder of 272.
The next digit of our result is 1. 
Result so far: 42300.138081
If we subtract 688 from 960, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 15:
When dividing 2720 by 688, we get 3 with a remainder of 656.
Record the quotient 3 as the next digit in the result. 
Result so far: 42300.1380813
If we take 2064 away from 2720, we end up with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Step 16:
688 goes into 6560 9 times with a remainder of 368.
Record the quotient 9 as the next digit in the result. 
Result so far: 42300.13808139
Subtracting 6192 from 6560 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final outcome is 42300.13808139, with a leftover of 3.68e-07.
