26099890 divided by 4 
We want to figure out the number of times 26099890 can be divided by 4.

Step 1:
The number 4 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 4

Step 2:
4 can be fit into 26 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 24 from 26 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 4

Going ahead to step 3:
4 goes into 20 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 65.0
The remainder is 0 after subtracting 20 from 20.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 4

Going ahead to step 4:
4 can be fit into 9 2 times, resulting in a remainder of 1.
The next digit of our result is 2. 
Result so far: 652.0
The remainder is 1 after subtracting 8 from 9.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 4

Moving on to step 5:
4 goes into 19 4 times with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 6524.0
Deduct 16 from 19 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 4

Going ahead to step 6:
38 divided by 4 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 65249.0
If we subtract 36 from 38, we get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 4

Advancing to step 7:
4 can be fit into 29 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 652497.0
Subtract 28 from 29 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 4

Going ahead to step 8:
10 divided by 4 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 6524972.0
Deduct 8 from 10 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 6524972.5
Subtract 20 from 20 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6524972.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
When dividing 0 by 4, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6524972.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 6524972.5 with a remaining 0.0.
