We're dividing 43689621 by 766 
We're looking to find how many times 766 goes into 43689621.

On to step 1:
4 divided by 766 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 766

Step 2:
If we divide 43 by 766, we get 0 and a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 766

Let's proceed to step 3:
766 goes into 436 0 times with a remainder of 436.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 436 leaves us with 436.
Append the next digit (8) from the dividend to 436 and continue with: 4368 / 766

Let's proceed to step 4:
766 can be fit into 4368 5 times, resulting in a remainder of 538.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 3830 from 4368, we get 538.
Fetch the next digit (9) from the dividend, attach it to 538 and continue: 5389 / 766

Step 5:
5389 divided by 766 is 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Deduct 5362 from 5389 and we're left with 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 766

Step 6:
276 divided by 766 is 0 with a remainder of 276.
Put 0 as the next digit of the answer. 
Result so far: 570.0
Subtracting 0 from 276 leaves us with 276.
Grab the next digit (2) from the dividend, add it to 276, then carry on: 2762 / 766

Going ahead to step 7:
If we divide 2762 by 766, we get 3 and a remainder of 464.
The next digit of our result is 3. 
Result so far: 5703.0
If we take 2298 away from 2762, we end up with 464.
Take the next digit (1) from the dividend and append it to 464, then repeat: 4641 / 766

Moving on to step 8:
The number 766 fits into 4641 6 times, leaving a remainder of 45.
Put 6 as the next digit of the answer. 
Result so far: 57036.0
Subtract 4596 from 4641 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
766 can be fit into 450 0 times, resulting in a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 57036.0
Deduct 0 from 450 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 10:
766 goes into 4500 5 times with a remainder of 670.
The number 5 becomes the next digit in our result. 
Result so far: 57036.05
Deduct 3830 from 4500 and we're left with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Moving on to step 11:
The number 766 fits into 6700 8 times, leaving a remainder of 572.
Use 8 as the next digit of our solution. 
Result so far: 57036.058
Subtracting 6128 from 6700 leaves us with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Advancing to step 12:
766 can be fit into 5720 7 times, resulting in a remainder of 358.
Put 7 as the next digit of the answer. 
Result so far: 57036.0587
Subtract 5362 from 5720 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 13:
When dividing 3580 by 766, we get 4 with a remainder of 516.
Use 4 as the next digit of our solution. 
Result so far: 57036.05874
Subtract 3064 from 3580 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 14:
The number 766 fits into 5160 6 times, leaving a remainder of 564.
The number 6 becomes the next digit in our result. 
Result so far: 57036.058746
Subtract 4596 from 5160 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Advancing to step 15:
If we divide 5640 by 766, we get 7 and a remainder of 278.
The number 7 becomes the next digit in our result. 
Result so far: 57036.0587467
Subtract 5362 from 5640 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Moving on to step 16:
766 goes into 2780 3 times with a remainder of 482.
Write down 3 as next digit of the result. 
Result so far: 57036.05874673
Deduct 2298 from 2780 and we're left with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

In conclusion, the division gives 57036.05874673 with a balance of 4.82e-07.
