43165829 ÷ 536 
We want to figure out the number of times 43165829 can be divided by 536.

Step 1:
When dividing 4 by 536, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 536

Advancing to step 2:
When dividing 43 by 536, we get 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 536

Going ahead to step 3:
536 can be fit into 431 0 times, resulting in a remainder of 431.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 431, we end up with 431.
Take the next digit (6) from the dividend and append it to 431, then repeat: 4316 / 536

On to step 4:
The number 536 fits into 4316 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 4288 from 4316 to get 28.
Fetch the next digit (5) from the dividend, attach it to 28 and continue: 285 / 536

Step 5:
When dividing 285 by 536, we get 0 with a remainder of 285.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
If we subtract 0 from 285, we get 285.
Bring next digit (8) of the dividend behind the 285 and repeat the process: 2858 / 536

Moving on to step 6:
536 can be fit into 2858 5 times, resulting in a remainder of 178.
Use 5 as the next digit of our solution. 
Result so far: 805.0
If we subtract 2680 from 2858, we get 178.
Append the next digit (2) from the dividend to 178 and continue with: 1782 / 536

Going ahead to step 7:
When dividing 1782 by 536, we get 3 with a remainder of 174.
Use 3 as the next digit of our solution. 
Result so far: 8053.0
Deduct 1608 from 1782 and we're left with 174.
Bring next digit (9) of the dividend behind the 174 and repeat the process: 1749 / 536

Advancing to step 8:
536 can be fit into 1749 3 times, resulting in a remainder of 141.
The number 3 becomes the next digit in our result. 
Result so far: 80533.0
Deduct 1608 from 1749 and we're left with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 9:
536 goes into 1410 2 times with a remainder of 338.
The next digit of our result is 2. 
Result so far: 80533.2
Subtract 1072 from 1410 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Step 10:
536 goes into 3380 6 times with a remainder of 164.
The number 6 becomes the next digit in our result. 
Result so far: 80533.26
Subtracting 3216 from 3380 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 11:
The number 536 fits into 1640 3 times, leaving a remainder of 32.
The next digit of our result is 3. 
Result so far: 80533.263
Subtracting 1608 from 1640 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.

Advancing to step 12:
536 goes into 320 0 times with a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 80533.263
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 13:
3200 divided by 536 is 5 with a remainder of 520.
Record the quotient 5 as the next digit in the result. 
Result so far: 80533.26305
Deduct 2680 from 3200 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 14:
536 goes into 5200 9 times with a remainder of 376.
The next digit of our result is 9. 
Result so far: 80533.263059
Deduct 4824 from 5200 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 15:
3760 divided by 536 is 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 80533.2630597
Subtract 3752 from 3760 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 16:
536 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 80533.2630597
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 80533.2630597, with a leftover of 8e-08.
