100999 ÷ 26 
We want to figure out the number of times 100999 can be divided by 26.

Going ahead to step 1:
26 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 26

Going ahead to step 2:
If we divide 10 by 26, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 26

Step 3:
26 goes into 100 3 times with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 78 away from 100, we end up with 22.
Grab the next digit (9) from the dividend, add it to 22, then carry on: 229 / 26

Step 4:
The number 26 fits into 229 8 times, leaving a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Deduct 208 from 229 and we're left with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 26

Advancing to step 5:
26 goes into 219 8 times with a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 388.0
If we take 208 away from 219, we end up with 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 26

Step 6:
When dividing 119 by 26, we get 4 with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 3884.0
The remainder is 15 after subtracting 104 from 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
26 can be fit into 150 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 3884.5
Subtracting 130 from 150 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
When dividing 200 by 26, we get 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 3884.57
Deduct 182 from 200 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
180 divided by 26 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 3884.576
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
26 goes into 240 9 times with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 3884.5769
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
The number 26 fits into 60 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 3884.57692
If we take 52 away from 60, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
26 goes into 80 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3884.576923
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
20 divided by 26 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 3884.576923
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
The number 26 fits into 200 7 times, leaving a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 3884.57692307
If we take 182 away from 200, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 3884.57692307 with a balance of 1.8e-08.
