90955215 ÷ 811 
We want to figure out the number of times 90955215 can be divided by 811.

Step 1:
The number 811 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 811

Step 2:
When dividing 90 by 811, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Grab the next digit (9) from the dividend, add it to 90, then carry on: 909 / 811

Moving on to step 3:
811 can be fit into 909 1 times, resulting in a remainder of 98.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 811 from 909, we get 98.
Append the next digit (5) from the dividend to 98 and continue with: 985 / 811

Going ahead to step 4:
811 goes into 985 1 times with a remainder of 174.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 174 after subtracting 811 from 985.
Append the next digit (5) from the dividend to 174 and continue with: 1745 / 811

Step 5:
811 can be fit into 1745 2 times, resulting in a remainder of 123.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
The remainder is 123 after subtracting 1622 from 1745.
Take the next digit (2) from the dividend and append it to 123, then repeat: 1232 / 811

Step 6:
811 can be fit into 1232 1 times, resulting in a remainder of 421.
The next digit of our result is 1. 
Result so far: 1121.0
The remainder is 421 after subtracting 811 from 1232.
Bring next digit (1) of the dividend behind the 421 and repeat the process: 4211 / 811

Going ahead to step 7:
811 goes into 4211 5 times with a remainder of 156.
The number 5 becomes the next digit in our result. 
Result so far: 11215.0
The remainder is 156 after subtracting 4055 from 4211.
Bring next digit (5) of the dividend behind the 156 and repeat the process: 1565 / 811

Moving on to step 8:
When dividing 1565 by 811, we get 1 with a remainder of 754.
Write down 1 as next digit of the result. 
Result so far: 112151.0
The remainder is 754 after subtracting 811 from 1565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

On to step 9:
811 goes into 7540 9 times with a remainder of 241.
The number 9 becomes the next digit in our result. 
Result so far: 112151.9
Deduct 7299 from 7540 and we're left with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Going ahead to step 10:
The number 811 fits into 2410 2 times, leaving a remainder of 788.
The number 2 becomes the next digit in our result. 
Result so far: 112151.92
If we take 1622 away from 2410, we end up with 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Moving on to step 11:
811 can be fit into 7880 9 times, resulting in a remainder of 581.
The next digit of our result is 9. 
Result so far: 112151.929
If we subtract 7299 from 7880, we get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

On to step 12:
If we divide 5810 by 811, we get 7 and a remainder of 133.
Use 7 as the next digit of our solution. 
Result so far: 112151.9297
Subtracting 5677 from 5810 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 13:
811 goes into 1330 1 times with a remainder of 519.
Record the quotient 1 as the next digit in the result. 
Result so far: 112151.92971
If we subtract 811 from 1330, we get 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Moving on to step 14:
The number 811 fits into 5190 6 times, leaving a remainder of 324.
Record the quotient 6 as the next digit in the result. 
Result so far: 112151.929716
The remainder is 324 after subtracting 4866 from 5190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 15:
The number 811 fits into 3240 3 times, leaving a remainder of 807.
Put 3 as the next digit of the answer. 
Result so far: 112151.9297163
If we subtract 2433 from 3240, we get 807.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8070, and continue the process.

Let's proceed to step 16:
When dividing 8070 by 811, we get 9 with a remainder of 771.
Put 9 as the next digit of the answer. 
Result so far: 112151.92971639
If we subtract 7299 from 8070, we get 771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

After the division, we end up with 112151.92971639 and a remainder of 7.71e-07.
