We look at the division of 81209216 by 911 
We want to figure out the number of times 81209216 can be divided by 911.

Going ahead to step 1:
If we divide 8 by 911, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 911

Let's proceed to step 2:
When dividing 81 by 911, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 911

Let's proceed to step 3:
The number 911 fits into 812 0 times, leaving a remainder of 812.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 812, we end up with 812.
Fetch the next digit (0) from the dividend, attach it to 812 and continue: 8120 / 911

Let's proceed to step 4:
911 goes into 8120 8 times with a remainder of 832.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 7288 from 8120, we get 832.
Fetch the next digit (9) from the dividend, attach it to 832 and continue: 8329 / 911

Let's proceed to step 5:
When dividing 8329 by 911, we get 9 with a remainder of 130.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Subtract 8199 from 8329 to get 130.
Fetch the next digit (2) from the dividend, attach it to 130 and continue: 1302 / 911

Let's proceed to step 6:
When dividing 1302 by 911, we get 1 with a remainder of 391.
The next digit of our result is 1. 
Result so far: 891.0
Subtracting 911 from 1302 leaves us with 391.
Fetch the next digit (1) from the dividend, attach it to 391 and continue: 3911 / 911

On to step 7:
3911 divided by 911 is 4 with a remainder of 267.
The next digit of our result is 4. 
Result so far: 8914.0
Subtract 3644 from 3911 to get 267.
Append the next digit (6) from the dividend to 267 and continue with: 2676 / 911

Let's proceed to step 8:
2676 divided by 911 is 2 with a remainder of 854.
Write down 2 as next digit of the result. 
Result so far: 89142.0
Deduct 1822 from 2676 and we're left with 854.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8540, and continue the process.

Let's proceed to step 9:
8540 divided by 911 is 9 with a remainder of 341.
Write down 9 as next digit of the result. 
Result so far: 89142.9
Deduct 8199 from 8540 and we're left with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 10:
911 goes into 3410 3 times with a remainder of 677.
Record the quotient 3 as the next digit in the result. 
Result so far: 89142.93
If we subtract 2733 from 3410, we get 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Let's proceed to step 11:
The number 911 fits into 6770 7 times, leaving a remainder of 393.
Use 7 as the next digit of our solution. 
Result so far: 89142.937
Subtract 6377 from 6770 to get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Moving on to step 12:
3930 divided by 911 is 4 with a remainder of 286.
The next digit of our result is 4. 
Result so far: 89142.9374
If we take 3644 away from 3930, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 13:
If we divide 2860 by 911, we get 3 and a remainder of 127.
The number 3 becomes the next digit in our result. 
Result so far: 89142.93743
Subtracting 2733 from 2860 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 14:
When dividing 1270 by 911, we get 1 with a remainder of 359.
Record the quotient 1 as the next digit in the result. 
Result so far: 89142.937431
The remainder is 359 after subtracting 911 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Moving on to step 15:
The number 911 fits into 3590 3 times, leaving a remainder of 857.
Use 3 as the next digit of our solution. 
Result so far: 89142.9374313
The remainder is 857 after subtracting 2733 from 3590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8570, and continue the process.

On to step 16:
When dividing 8570 by 911, we get 9 with a remainder of 371.
Record the quotient 9 as the next digit in the result. 
Result so far: 89142.93743139
If we take 8199 away from 8570, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

The final result is 89142.93743139 with a remainder of 3.71e-07.
