45303321 ÷ 866 
We're looking to find how many times 866 goes into 45303321.

On to step 1:
When dividing 4 by 866, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 866

On to step 2:
If we divide 45 by 866, we get 0 and a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 866

Moving on to step 3:
866 can be fit into 453 0 times, resulting in a remainder of 453.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 453, we get 453.
Fetch the next digit (0) from the dividend, attach it to 453 and continue: 4530 / 866

Going ahead to step 4:
866 goes into 4530 5 times with a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 4330 from 4530 and we're left with 200.
Append the next digit (3) from the dividend to 200 and continue with: 2003 / 866

Advancing to step 5:
866 goes into 2003 2 times with a remainder of 271.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Subtract 1732 from 2003 to get 271.
Append the next digit (3) from the dividend to 271 and continue with: 2713 / 866

Let's proceed to step 6:
The number 866 fits into 2713 3 times, leaving a remainder of 115.
Put 3 as the next digit of the answer. 
Result so far: 523.0
The remainder is 115 after subtracting 2598 from 2713.
Take the next digit (2) from the dividend and append it to 115, then repeat: 1152 / 866

Going ahead to step 7:
866 can be fit into 1152 1 times, resulting in a remainder of 286.
Write down 1 as next digit of the result. 
Result so far: 5231.0
If we subtract 866 from 1152, we get 286.
Bring next digit (1) of the dividend behind the 286 and repeat the process: 2861 / 866

Advancing to step 8:
2861 divided by 866 is 3 with a remainder of 263.
Write down 3 as next digit of the result. 
Result so far: 52313.0
Subtracting 2598 from 2861 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Moving on to step 9:
The number 866 fits into 2630 3 times, leaving a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 52313.3
Subtracting 2598 from 2630 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
The number 866 fits into 320 0 times, leaving a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 52313.3
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 11:
866 can be fit into 3200 3 times, resulting in a remainder of 602.
Record the quotient 3 as the next digit in the result. 
Result so far: 52313.303
Subtract 2598 from 3200 to get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Step 12:
When dividing 6020 by 866, we get 6 with a remainder of 824.
Record the quotient 6 as the next digit in the result. 
Result so far: 52313.3036
If we subtract 5196 from 6020, we get 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Step 13:
866 can be fit into 8240 9 times, resulting in a remainder of 446.
The number 9 becomes the next digit in our result. 
Result so far: 52313.30369
If we take 7794 away from 8240, we end up with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 14:
866 goes into 4460 5 times with a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 52313.303695
Deduct 4330 from 4460 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 15:
866 can be fit into 1300 1 times, resulting in a remainder of 434.
The next digit of our result is 1. 
Result so far: 52313.3036951
If we take 866 away from 1300, we end up with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Advancing to step 16:
The number 866 fits into 4340 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 52313.30369515
Subtracting 4330 from 4340 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 52313.30369515 with a balance of 1e-08.
