Let's divide 36643019 by 866
We want to figure out the number of times 36643019 can be divided by 866.

Step 1:
If we divide 3 by 866, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 866

Advancing to step 2:
866 goes into 36 0 times with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 866

Let's proceed to step 3:
The number 866 fits into 366 0 times, leaving a remainder of 366.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 366 and we're left with 366.
Include the next digit (4) from the dividend after 366, then repeat: 3664 / 866

Advancing to step 4:
866 can be fit into 3664 4 times, resulting in a remainder of 200.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 3464 from 3664, we get 200.
Grab the next digit (3) from the dividend, add it to 200, then carry on: 2003 / 866

Going ahead to step 5:
866 goes into 2003 2 times with a remainder of 271.
The next digit of our result is 2. 
Result so far: 42.0
The remainder is 271 after subtracting 1732 from 2003.
Take the next digit (0) from the dividend and append it to 271, then repeat: 2710 / 866

Going ahead to step 6:
2710 divided by 866 is 3 with a remainder of 112.
Write down 3 as next digit of the result. 
Result so far: 423.0
If we subtract 2598 from 2710, we get 112.
Take the next digit (1) from the dividend and append it to 112, then repeat: 1121 / 866

Let's proceed to step 7:
If we divide 1121 by 866, we get 1 and a remainder of 255.
Use 1 as the next digit of our solution. 
Result so far: 4231.0
If we subtract 866 from 1121, we get 255.
Fetch the next digit (9) from the dividend, attach it to 255 and continue: 2559 / 866

Going ahead to step 8:
866 can be fit into 2559 2 times, resulting in a remainder of 827.
Record the quotient 2 as the next digit in the result. 
Result so far: 42312.0
If we take 1732 away from 2559, we end up with 827.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8270, and continue the process.

On to step 9:
When dividing 8270 by 866, we get 9 with a remainder of 476.
The number 9 becomes the next digit in our result. 
Result so far: 42312.9
If we take 7794 away from 8270, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Step 10:
When dividing 4760 by 866, we get 5 with a remainder of 430.
Use 5 as the next digit of our solution. 
Result so far: 42312.95
Subtract 4330 from 4760 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 11:
4300 divided by 866 is 4 with a remainder of 836.
Record the quotient 4 as the next digit in the result. 
Result so far: 42312.954
If we subtract 3464 from 4300, we get 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Advancing to step 12:
The number 866 fits into 8360 9 times, leaving a remainder of 566.
Record the quotient 9 as the next digit in the result. 
Result so far: 42312.9549
If we take 7794 away from 8360, we end up with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Let's proceed to step 13:
When dividing 5660 by 866, we get 6 with a remainder of 464.
Write down 6 as next digit of the result. 
Result so far: 42312.95496
The remainder is 464 after subtracting 5196 from 5660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 14:
866 can be fit into 4640 5 times, resulting in a remainder of 310.
The next digit of our result is 5. 
Result so far: 42312.954965
The remainder is 310 after subtracting 4330 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 15:
When dividing 3100 by 866, we get 3 with a remainder of 502.
Write down 3 as next digit of the result. 
Result so far: 42312.9549653
The remainder is 502 after subtracting 2598 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Advancing to step 16:
When dividing 5020 by 866, we get 5 with a remainder of 690.
The number 5 becomes the next digit in our result. 
Result so far: 42312.95496535
Deduct 4330 from 5020 and we're left with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

The final outcome is 42312.95496535, with a leftover of 6.9e-07.
