We look at the division of 28504235 by 109 
We want to figure out the number of times 28504235 can be divided by 109.

Moving on to step 1:
109 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 109

On to step 2:
If we divide 28 by 109, we get 0 and a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 109

Advancing to step 3:
If we divide 285 by 109, we get 2 and a remainder of 67.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 218 from 285 to get 67.
Grab the next digit (0) from the dividend, add it to 67, then carry on: 670 / 109

Going ahead to step 4:
109 can be fit into 670 6 times, resulting in a remainder of 16.
The next digit of our result is 6. 
Result so far: 26.0
The remainder is 16 after subtracting 654 from 670.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 109

Step 5:
109 goes into 164 1 times with a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 261.0
If we take 109 away from 164, we end up with 55.
Append the next digit (2) from the dividend to 55 and continue with: 552 / 109

Going ahead to step 6:
If we divide 552 by 109, we get 5 and a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 2615.0
If we take 545 away from 552, we end up with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 109

Going ahead to step 7:
73 divided by 109 is 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 26150.0
If we take 0 away from 73, we end up with 73.
Fetch the next digit (5) from the dividend, attach it to 73 and continue: 735 / 109

Advancing to step 8:
The number 109 fits into 735 6 times, leaving a remainder of 81.
Put 6 as the next digit of the answer. 
Result so far: 261506.0
Deduct 654 from 735 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 9:
109 can be fit into 810 7 times, resulting in a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 261506.7
Subtract 763 from 810 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 10:
If we divide 470 by 109, we get 4 and a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 261506.74
The remainder is 34 after subtracting 436 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 11:
If we divide 340 by 109, we get 3 and a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 261506.743
If we take 327 away from 340, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
The number 109 fits into 130 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 261506.7431
If we subtract 109 from 130, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 13:
The number 109 fits into 210 1 times, leaving a remainder of 101.
Record the quotient 1 as the next digit in the result. 
Result so far: 261506.74311
Subtract 109 from 210 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Our division results in 261506.74311 with a remaining 0.000101.
