26463806 divided by 643 
We want to divide 26463806 by 643.

Let's proceed to step 1:
643 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 643

Going ahead to step 2:
If we divide 26 by 643, we get 0 and a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 643

Step 3:
643 goes into 264 0 times with a remainder of 264.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 264, we end up with 264.
Append the next digit (6) from the dividend to 264 and continue with: 2646 / 643

Step 4:
If we divide 2646 by 643, we get 4 and a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 74 after subtracting 2572 from 2646.
Append the next digit (3) from the dividend to 74 and continue with: 743 / 643

On to step 5:
643 goes into 743 1 times with a remainder of 100.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 643 from 743 leaves us with 100.
Include the next digit (8) from the dividend after 100, then repeat: 1008 / 643

Let's proceed to step 6:
When dividing 1008 by 643, we get 1 with a remainder of 365.
Write down 1 as next digit of the result. 
Result so far: 411.0
If we subtract 643 from 1008, we get 365.
Grab the next digit (0) from the dividend, add it to 365, then carry on: 3650 / 643

Going ahead to step 7:
3650 divided by 643 is 5 with a remainder of 435.
Use 5 as the next digit of our solution. 
Result so far: 4115.0
The remainder is 435 after subtracting 3215 from 3650.
Take the next digit (6) from the dividend and append it to 435, then repeat: 4356 / 643

Let's proceed to step 8:
643 can be fit into 4356 6 times, resulting in a remainder of 498.
The number 6 becomes the next digit in our result. 
Result so far: 41156.0
Subtracting 3858 from 4356 leaves us with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Going ahead to step 9:
When dividing 4980 by 643, we get 7 with a remainder of 479.
Put 7 as the next digit of the answer. 
Result so far: 41156.7
The remainder is 479 after subtracting 4501 from 4980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

On to step 10:
If we divide 4790 by 643, we get 7 and a remainder of 289.
The number 7 becomes the next digit in our result. 
Result so far: 41156.77
Subtracting 4501 from 4790 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

The quotient of the division is 41156.77, and the remainder is 0.289.
