We're dividing 85515452 by 823 
We want to figure out the number of times 85515452 can be divided by 823.

Step 1:
When dividing 8 by 823, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 823

Moving on to step 2:
823 goes into 85 0 times with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Include the next digit (5) from the dividend after 85, then repeat: 855 / 823

Let's proceed to step 3:
855 divided by 823 is 1 with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 32 after subtracting 823 from 855.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 823

Advancing to step 4:
The number 823 fits into 321 0 times, leaving a remainder of 321.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 321, we end up with 321.
Fetch the next digit (5) from the dividend, attach it to 321 and continue: 3215 / 823

Going ahead to step 5:
3215 divided by 823 is 3 with a remainder of 746.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
Subtract 2469 from 3215 to get 746.
Include the next digit (4) from the dividend after 746, then repeat: 7464 / 823

Advancing to step 6:
If we divide 7464 by 823, we get 9 and a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 1039.0
The remainder is 57 after subtracting 7407 from 7464.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 823

Going ahead to step 7:
The number 823 fits into 575 0 times, leaving a remainder of 575.
Write down 0 as next digit of the result. 
Result so far: 10390.0
Subtract 0 from 575 to get 575.
Grab the next digit (2) from the dividend, add it to 575, then carry on: 5752 / 823

Advancing to step 8:
5752 divided by 823 is 6 with a remainder of 814.
Use 6 as the next digit of our solution. 
Result so far: 103906.0
If we subtract 4938 from 5752, we get 814.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8140, and continue the process.

Moving on to step 9:
8140 divided by 823 is 9 with a remainder of 733.
Write down 9 as next digit of the result. 
Result so far: 103906.9
Subtract 7407 from 8140 to get 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

Moving on to step 10:
823 can be fit into 7330 8 times, resulting in a remainder of 746.
Record the quotient 8 as the next digit in the result. 
Result so far: 103906.98
Subtract 6584 from 7330 to get 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Moving on to step 11:
The number 823 fits into 7460 9 times, leaving a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 103906.989
The remainder is 53 after subtracting 7407 from 7460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 12:
823 goes into 530 0 times with a remainder of 530.
Use 0 as the next digit of our solution. 
Result so far: 103906.989
Subtract 0 from 530 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 13:
5300 divided by 823 is 6 with a remainder of 362.
Record the quotient 6 as the next digit in the result. 
Result so far: 103906.98906
Deduct 4938 from 5300 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Let's proceed to step 14:
When dividing 3620 by 823, we get 4 with a remainder of 328.
Write down 4 as next digit of the result. 
Result so far: 103906.989064
Subtracting 3292 from 3620 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 15:
823 goes into 3280 3 times with a remainder of 811.
Write down 3 as next digit of the result. 
Result so far: 103906.9890643
Deduct 2469 from 3280 and we're left with 811.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8110, and continue the process.

Advancing to step 16:
8110 divided by 823 is 9 with a remainder of 703.
Put 9 as the next digit of the answer. 
Result so far: 103906.98906439
If we take 7407 away from 8110, we end up with 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Our division results in 103906.98906439 with a remaining 7.03e-07.
