45817077 ÷ 866 
We want to divide 45817077 by 866.

Advancing to step 1:
The number 866 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 866

Let's proceed to step 2:
866 can be fit into 45 0 times, resulting in a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 866

Advancing to step 3:
458 divided by 866 is 0 with a remainder of 458.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 458, we get 458.
Include the next digit (1) from the dividend after 458, then repeat: 4581 / 866

Step 4:
The number 866 fits into 4581 5 times, leaving a remainder of 251.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 4330 from 4581 to get 251.
Append the next digit (7) from the dividend to 251 and continue with: 2517 / 866

Let's proceed to step 5:
When dividing 2517 by 866, we get 2 with a remainder of 785.
Use 2 as the next digit of our solution. 
Result so far: 52.0
If we take 1732 away from 2517, we end up with 785.
Append the next digit (0) from the dividend to 785 and continue with: 7850 / 866

Advancing to step 6:
7850 divided by 866 is 9 with a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 529.0
If we take 7794 away from 7850, we end up with 56.
Grab the next digit (7) from the dividend, add it to 56, then carry on: 567 / 866

Advancing to step 7:
866 can be fit into 567 0 times, resulting in a remainder of 567.
Write down 0 as next digit of the result. 
Result so far: 5290.0
Deduct 0 from 567 and we're left with 567.
Fetch the next digit (7) from the dividend, attach it to 567 and continue: 5677 / 866

Moving on to step 8:
The number 866 fits into 5677 6 times, leaving a remainder of 481.
The next digit of our result is 6. 
Result so far: 52906.0
Deduct 5196 from 5677 and we're left with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Let's proceed to step 9:
866 can be fit into 4810 5 times, resulting in a remainder of 480.
Put 5 as the next digit of the answer. 
Result so far: 52906.5
Deduct 4330 from 4810 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 10:
866 can be fit into 4800 5 times, resulting in a remainder of 470.
Record the quotient 5 as the next digit in the result. 
Result so far: 52906.55
Subtract 4330 from 4800 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

The final result is 52906.55 with a remainder of 0.47.
