We're dividing 2658352 by 688 
We want to divide 2658352 by 688.

Step 1:
If we divide 2 by 688, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 688

Let's proceed to step 2:
26 divided by 688 is 0 with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 688

Moving on to step 3:
When dividing 265 by 688, we get 0 with a remainder of 265.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 265, we get 265.
Fetch the next digit (8) from the dividend, attach it to 265 and continue: 2658 / 688

On to step 4:
If we divide 2658 by 688, we get 3 and a remainder of 594.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 2064 from 2658, we get 594.
Take the next digit (3) from the dividend and append it to 594, then repeat: 5943 / 688

On to step 5:
5943 divided by 688 is 8 with a remainder of 439.
Put 8 as the next digit of the answer. 
Result so far: 38.0
The remainder is 439 after subtracting 5504 from 5943.
Take the next digit (5) from the dividend and append it to 439, then repeat: 4395 / 688

Step 6:
4395 divided by 688 is 6 with a remainder of 267.
Put 6 as the next digit of the answer. 
Result so far: 386.0
Subtracting 4128 from 4395 leaves us with 267.
Grab the next digit (2) from the dividend, add it to 267, then carry on: 2672 / 688

Step 7:
When dividing 2672 by 688, we get 3 with a remainder of 608.
The number 3 becomes the next digit in our result. 
Result so far: 3863.0
Subtract 2064 from 2672 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.

Step 8:
688 can be fit into 6080 8 times, resulting in a remainder of 576.
Put 8 as the next digit of the answer. 
Result so far: 3863.8
Subtracting 5504 from 6080 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 9:
If we divide 5760 by 688, we get 8 and a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 3863.88
The remainder is 256 after subtracting 5504 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Our division results in 3863.88 with a remaining 0.256.
