We look at the division of 45791487 by 823 
We're looking to find how many times 823 goes into 45791487.

Advancing to step 1:
If we divide 4 by 823, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 823

Step 2:
45 divided by 823 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (7) from the dividend to 45 and continue with: 457 / 823

Step 3:
The number 823 fits into 457 0 times, leaving a remainder of 457.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 457 after subtracting 0 from 457.
Bring next digit (9) of the dividend behind the 457 and repeat the process: 4579 / 823

Moving on to step 4:
4579 divided by 823 is 5 with a remainder of 464.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 4115 from 4579 and we're left with 464.
Grab the next digit (1) from the dividend, add it to 464, then carry on: 4641 / 823

Step 5:
When dividing 4641 by 823, we get 5 with a remainder of 526.
Put 5 as the next digit of the answer. 
Result so far: 55.0
If we subtract 4115 from 4641, we get 526.
Take the next digit (4) from the dividend and append it to 526, then repeat: 5264 / 823

Going ahead to step 6:
If we divide 5264 by 823, we get 6 and a remainder of 326.
Put 6 as the next digit of the answer. 
Result so far: 556.0
Subtracting 4938 from 5264 leaves us with 326.
Append the next digit (8) from the dividend to 326 and continue with: 3268 / 823

Moving on to step 7:
When dividing 3268 by 823, we get 3 with a remainder of 799.
The number 3 becomes the next digit in our result. 
Result so far: 5563.0
Subtracting 2469 from 3268 leaves us with 799.
Append the next digit (7) from the dividend to 799 and continue with: 7997 / 823

Let's proceed to step 8:
If we divide 7997 by 823, we get 9 and a remainder of 590.
Record the quotient 9 as the next digit in the result. 
Result so far: 55639.0
If we subtract 7407 from 7997, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Let's proceed to step 9:
The number 823 fits into 5900 7 times, leaving a remainder of 139.
Use 7 as the next digit of our solution. 
Result so far: 55639.7
Subtract 5761 from 5900 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Let's proceed to step 10:
If we divide 1390 by 823, we get 1 and a remainder of 567.
Use 1 as the next digit of our solution. 
Result so far: 55639.71
Subtract 823 from 1390 to get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Advancing to step 11:
The number 823 fits into 5670 6 times, leaving a remainder of 732.
Record the quotient 6 as the next digit in the result. 
Result so far: 55639.716
Subtracting 4938 from 5670 leaves us with 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Advancing to step 12:
823 can be fit into 7320 8 times, resulting in a remainder of 736.
Write down 8 as next digit of the result. 
Result so far: 55639.7168
The remainder is 736 after subtracting 6584 from 7320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Step 13:
If we divide 7360 by 823, we get 8 and a remainder of 776.
Write down 8 as next digit of the result. 
Result so far: 55639.71688
Deduct 6584 from 7360 and we're left with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

The final result is 55639.71688 with a remainder of 0.000776.
