We're dividing 78867100 by 405 
Our goal is to divide 78867100 by 405.

Advancing to step 1:
7 divided by 405 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 405

Moving on to step 2:
78 divided by 405 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Fetch the next digit (8) from the dividend, attach it to 78 and continue: 788 / 405

Step 3:
If we divide 788 by 405, we get 1 and a remainder of 383.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 405 from 788, we get 383.
Grab the next digit (6) from the dividend, add it to 383, then carry on: 3836 / 405

Let's proceed to step 4:
3836 divided by 405 is 9 with a remainder of 191.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 3645 from 3836 to get 191.
Include the next digit (7) from the dividend after 191, then repeat: 1917 / 405

Advancing to step 5:
405 can be fit into 1917 4 times, resulting in a remainder of 297.
The next digit of our result is 4. 
Result so far: 194.0
If we take 1620 away from 1917, we end up with 297.
Grab the next digit (1) from the dividend, add it to 297, then carry on: 2971 / 405

Let's proceed to step 6:
When dividing 2971 by 405, we get 7 with a remainder of 136.
Write down 7 as next digit of the result. 
Result so far: 1947.0
Deduct 2835 from 2971 and we're left with 136.
Bring next digit (0) of the dividend behind the 136 and repeat the process: 1360 / 405

Going ahead to step 7:
If we divide 1360 by 405, we get 3 and a remainder of 145.
Use 3 as the next digit of our solution. 
Result so far: 19473.0
Subtracting 1215 from 1360 leaves us with 145.
Take the next digit (0) from the dividend and append it to 145, then repeat: 1450 / 405

Let's proceed to step 8:
The number 405 fits into 1450 3 times, leaving a remainder of 235.
Put 3 as the next digit of the answer. 
Result so far: 194733.0
Subtracting 1215 from 1450 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 9:
If we divide 2350 by 405, we get 5 and a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 194733.5
Subtract 2025 from 2350 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 10:
3250 divided by 405 is 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 194733.58
If we subtract 3240 from 3250, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
405 goes into 100 0 times with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 194733.58
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 12:
405 goes into 1000 2 times with a remainder of 190.
Write down 2 as next digit of the result. 
Result so far: 194733.5802
Deduct 810 from 1000 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 13:
The number 405 fits into 1900 4 times, leaving a remainder of 280.
The next digit of our result is 4. 
Result so far: 194733.58024
Subtract 1620 from 1900 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 14:
If we divide 2800 by 405, we get 6 and a remainder of 370.
The number 6 becomes the next digit in our result. 
Result so far: 194733.580246
Deduct 2430 from 2800 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 15:
405 can be fit into 3700 9 times, resulting in a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 194733.5802469
Deduct 3645 from 3700 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 16:
The number 405 fits into 550 1 times, leaving a remainder of 145.
The next digit of our result is 1. 
Result so far: 194733.58024691
If we take 405 away from 550, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final outcome is 194733.58024691, with a leftover of 1.45e-07.
