Let's divide 85241587 by 109
We want to divide 85241587 by 109.

Step 1:
The number 109 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 109

On to step 2:
The number 109 fits into 85 0 times, leaving a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Fetch the next digit (2) from the dividend, attach it to 85 and continue: 852 / 109

Step 3:
When dividing 852 by 109, we get 7 with a remainder of 89.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 89 after subtracting 763 from 852.
Bring next digit (4) of the dividend behind the 89 and repeat the process: 894 / 109

Moving on to step 4:
109 can be fit into 894 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we subtract 872 from 894, we get 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 109

Advancing to step 5:
109 can be fit into 221 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 782.0
If we subtract 218 from 221, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 109

Step 6:
109 can be fit into 35 0 times, resulting in a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 7820.0
If we take 0 away from 35, we end up with 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 109

On to step 7:
The number 109 fits into 358 3 times, leaving a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 78203.0
Subtracting 327 from 358 leaves us with 31.
Take the next digit (7) from the dividend and append it to 31, then repeat: 317 / 109

Advancing to step 8:
109 goes into 317 2 times with a remainder of 99.
Use 2 as the next digit of our solution. 
Result so far: 782032.0
Subtract 218 from 317 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 9:
990 divided by 109 is 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 782032.9
Subtracting 981 from 990 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
If we divide 90 by 109, we get 0 and a remainder of 90.
The next digit of our result is 0. 
Result so far: 782032.9
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 11:
109 goes into 900 8 times with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 782032.908
Subtract 872 from 900 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
280 divided by 109 is 2 with a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 782032.9082
If we subtract 218 from 280, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 13:
109 goes into 620 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 782032.90825
If we take 545 away from 620, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 14:
750 divided by 109 is 6 with a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 782032.908256
Subtract 654 from 750 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 15:
When dividing 960 by 109, we get 8 with a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 782032.9082568
Subtracting 872 from 960 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 16:
The number 109 fits into 880 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 782032.90825688
The remainder is 8 after subtracting 872 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 782032.90825688 and a remainder of 8e-09.
