We're dividing 68455807 by 405 
Our goal is to divide 68455807 by 405.

On to step 1:
When dividing 6 by 405, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 405

Step 2:
When dividing 68 by 405, we get 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Append the next digit (4) from the dividend to 68 and continue with: 684 / 405

On to step 3:
684 divided by 405 is 1 with a remainder of 279.
The next digit of our result is 1. 
Result so far: 1.0
If we take 405 away from 684, we end up with 279.
Fetch the next digit (5) from the dividend, attach it to 279 and continue: 2795 / 405

Moving on to step 4:
405 goes into 2795 6 times with a remainder of 365.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 2430 from 2795 to get 365.
Grab the next digit (5) from the dividend, add it to 365, then carry on: 3655 / 405

On to step 5:
The number 405 fits into 3655 9 times, leaving a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 169.0
Subtract 3645 from 3655 to get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 405

Moving on to step 6:
108 divided by 405 is 0 with a remainder of 108.
Write down 0 as next digit of the result. 
Result so far: 1690.0
If we take 0 away from 108, we end up with 108.
Take the next digit (0) from the dividend and append it to 108, then repeat: 1080 / 405

Advancing to step 7:
405 can be fit into 1080 2 times, resulting in a remainder of 270.
Write down 2 as next digit of the result. 
Result so far: 16902.0
Subtract 810 from 1080 to get 270.
Fetch the next digit (7) from the dividend, attach it to 270 and continue: 2707 / 405

Going ahead to step 8:
2707 divided by 405 is 6 with a remainder of 277.
The number 6 becomes the next digit in our result. 
Result so far: 169026.0
Deduct 2430 from 2707 and we're left with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Step 9:
405 can be fit into 2770 6 times, resulting in a remainder of 340.
Write down 6 as next digit of the result. 
Result so far: 169026.6
If we subtract 2430 from 2770, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 10:
405 can be fit into 3400 8 times, resulting in a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 169026.68
Deduct 3240 from 3400 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 11:
405 goes into 1600 3 times with a remainder of 385.
The number 3 becomes the next digit in our result. 
Result so far: 169026.683
Deduct 1215 from 1600 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 12:
When dividing 3850 by 405, we get 9 with a remainder of 205.
Use 9 as the next digit of our solution. 
Result so far: 169026.6839
Subtracting 3645 from 3850 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 13:
If we divide 2050 by 405, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 169026.68395
Subtract 2025 from 2050 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 14:
If we divide 250 by 405, we get 0 and a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 169026.68395
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 15:
405 can be fit into 2500 6 times, resulting in a remainder of 70.
Put 6 as the next digit of the answer. 
Result so far: 169026.6839506
Subtract 2430 from 2500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 16:
The number 405 fits into 700 1 times, leaving a remainder of 295.
Write down 1 as next digit of the result. 
Result so far: 169026.68395061
The remainder is 295 after subtracting 405 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

The final outcome is 169026.68395061, with a leftover of 2.95e-07.
