We look at the division of 12589011 by 811 
We want to figure out the number of times 12589011 can be divided by 811.

Step 1:
If we divide 1 by 811, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 811

Advancing to step 2:
12 divided by 811 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 811

Moving on to step 3:
811 goes into 125 0 times with a remainder of 125.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 125, we get 125.
Grab the next digit (8) from the dividend, add it to 125, then carry on: 1258 / 811

On to step 4:
The number 811 fits into 1258 1 times, leaving a remainder of 447.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 811 from 1258 leaves us with 447.
Include the next digit (9) from the dividend after 447, then repeat: 4479 / 811

Step 5:
811 can be fit into 4479 5 times, resulting in a remainder of 424.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 4055 from 4479 leaves us with 424.
Append the next digit (0) from the dividend to 424 and continue with: 4240 / 811

Step 6:
If we divide 4240 by 811, we get 5 and a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 155.0
If we subtract 4055 from 4240, we get 185.
Include the next digit (1) from the dividend after 185, then repeat: 1851 / 811

Moving on to step 7:
811 goes into 1851 2 times with a remainder of 229.
The next digit of our result is 2. 
Result so far: 1552.0
If we take 1622 away from 1851, we end up with 229.
Append the next digit (1) from the dividend to 229 and continue with: 2291 / 811

Moving on to step 8:
If we divide 2291 by 811, we get 2 and a remainder of 669.
The next digit of our result is 2. 
Result so far: 15522.0
Deduct 1622 from 2291 and we're left with 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

Moving on to step 9:
If we divide 6690 by 811, we get 8 and a remainder of 202.
Write down 8 as next digit of the result. 
Result so far: 15522.8
Subtract 6488 from 6690 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 10:
811 goes into 2020 2 times with a remainder of 398.
The next digit of our result is 2. 
Result so far: 15522.82
If we subtract 1622 from 2020, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 11:
811 can be fit into 3980 4 times, resulting in a remainder of 736.
Put 4 as the next digit of the answer. 
Result so far: 15522.824
Subtract 3244 from 3980 to get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Step 12:
The number 811 fits into 7360 9 times, leaving a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 15522.8249
Deduct 7299 from 7360 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 13:
811 can be fit into 610 0 times, resulting in a remainder of 610.
Record the quotient 0 as the next digit in the result. 
Result so far: 15522.8249
The remainder is 610 after subtracting 0 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 14:
When dividing 6100 by 811, we get 7 with a remainder of 423.
The number 7 becomes the next digit in our result. 
Result so far: 15522.824907
The remainder is 423 after subtracting 5677 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Step 15:
If we divide 4230 by 811, we get 5 and a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 15522.8249075
Subtract 4055 from 4230 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 16:
811 can be fit into 1750 2 times, resulting in a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 15522.82490752
Deduct 1622 from 1750 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

After the division, we end up with 15522.82490752 and a remainder of 1.28e-07.
