69169216 ÷ 409 
We want to divide 69169216 by 409.

Step 1:
The number 409 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 409

Advancing to step 2:
409 goes into 69 0 times with a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 409

Advancing to step 3:
691 divided by 409 is 1 with a remainder of 282.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 282 after subtracting 409 from 691.
Take the next digit (6) from the dividend and append it to 282, then repeat: 2826 / 409

Going ahead to step 4:
409 can be fit into 2826 6 times, resulting in a remainder of 372.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 2454 from 2826, we get 372.
Include the next digit (9) from the dividend after 372, then repeat: 3729 / 409

Step 5:
If we divide 3729 by 409, we get 9 and a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 169.0
Subtracting 3681 from 3729 leaves us with 48.
Fetch the next digit (2) from the dividend, attach it to 48 and continue: 482 / 409

Moving on to step 6:
The number 409 fits into 482 1 times, leaving a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 1691.0
Subtract 409 from 482 to get 73.
Take the next digit (1) from the dividend and append it to 73, then repeat: 731 / 409

Step 7:
409 goes into 731 1 times with a remainder of 322.
Use 1 as the next digit of our solution. 
Result so far: 16911.0
Subtracting 409 from 731 leaves us with 322.
Append the next digit (6) from the dividend to 322 and continue with: 3226 / 409

Step 8:
409 goes into 3226 7 times with a remainder of 363.
The number 7 becomes the next digit in our result. 
Result so far: 169117.0
If we take 2863 away from 3226, we end up with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Step 9:
The number 409 fits into 3630 8 times, leaving a remainder of 358.
Use 8 as the next digit of our solution. 
Result so far: 169117.8
If we subtract 3272 from 3630, we 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.

Let's proceed to step 10:
409 can be fit into 3580 8 times, resulting in a remainder of 308.
The next digit of our result is 8. 
Result so far: 169117.88
Subtract 3272 from 3580 to 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.

Our division results in 169117.88 with a remaining 0.308.
