89216755 ÷ 409 
Our goal is to divide 89216755 by 409.

Step 1:
If we divide 8 by 409, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 409

On to step 2:
409 can be fit into 89 0 times, resulting in a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Take the next digit (2) from the dividend and append it to 89, then repeat: 892 / 409

Moving on to step 3:
892 divided by 409 is 2 with a remainder of 74.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 818 from 892 to get 74.
Bring next digit (1) of the dividend behind the 74 and repeat the process: 741 / 409

Moving on to step 4:
When dividing 741 by 409, we get 1 with a remainder of 332.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 409 from 741 and we're left with 332.
Append the next digit (6) from the dividend to 332 and continue with: 3326 / 409

On to step 5:
The number 409 fits into 3326 8 times, leaving a remainder of 54.
The next digit of our result is 8. 
Result so far: 218.0
If we subtract 3272 from 3326, we get 54.
Include the next digit (7) from the dividend after 54, then repeat: 547 / 409

Let's proceed to step 6:
409 can be fit into 547 1 times, resulting in a remainder of 138.
The number 1 becomes the next digit in our result. 
Result so far: 2181.0
The remainder is 138 after subtracting 409 from 547.
Grab the next digit (5) from the dividend, add it to 138, then carry on: 1385 / 409

Advancing to step 7:
When dividing 1385 by 409, we get 3 with a remainder of 158.
Put 3 as the next digit of the answer. 
Result so far: 21813.0
The remainder is 158 after subtracting 1227 from 1385.
Grab the next digit (5) from the dividend, add it to 158, then carry on: 1585 / 409

Going ahead to step 8:
409 goes into 1585 3 times with a remainder of 358.
The next digit of our result is 3. 
Result so far: 218133.0
If we take 1227 away from 1585, we end up with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 9:
409 goes into 3580 8 times with a remainder of 308.
Write down 8 as next digit of the result. 
Result so far: 218133.8
If we subtract 3272 from 3580, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 10:
The number 409 fits into 3080 7 times, leaving a remainder of 217.
The number 7 becomes the next digit in our result. 
Result so far: 218133.87
If we subtract 2863 from 3080, we get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Going ahead to step 11:
409 can be fit into 2170 5 times, resulting in a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 218133.875
If we take 2045 away from 2170, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 12:
1250 divided by 409 is 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 218133.8753
The remainder is 23 after subtracting 1227 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 13:
230 divided by 409 is 0 with a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 218133.8753
Subtracting 0 from 230 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 14:
409 goes into 2300 5 times with a remainder of 255.
Write down 5 as next digit of the result. 
Result so far: 218133.875305
Subtracting 2045 from 2300 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 15:
409 goes into 2550 6 times with a remainder of 96.
The next digit of our result is 6. 
Result so far: 218133.8753056
If we subtract 2454 from 2550, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 16:
409 goes into 960 2 times with a remainder of 142.
Write down 2 as next digit of the result. 
Result so far: 218133.87530562
If we take 818 away from 960, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The final outcome is 218133.87530562, with a leftover of 1.42e-07.
