636173 divided by 78 
We want to figure out the number of times 636173 can be divided by 78.

Moving on to step 1:
6 divided by 78 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 78

Advancing to step 2:
63 divided by 78 is 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Include the next digit (6) from the dividend after 63, then repeat: 636 / 78

Advancing to step 3:
The number 78 fits into 636 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 624 from 636 leaves us with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 78

Advancing to step 4:
121 divided by 78 is 1 with a remainder of 43.
The next digit of our result is 1. 
Result so far: 81.0
Subtract 78 from 121 to get 43.
Fetch the next digit (7) from the dividend, attach it to 43 and continue: 437 / 78

On to step 5:
78 can be fit into 437 5 times, resulting in a remainder of 47.
Put 5 as the next digit of the answer. 
Result so far: 815.0
If we subtract 390 from 437, we get 47.
Append the next digit (3) from the dividend to 47 and continue with: 473 / 78

Let's proceed to step 6:
If we divide 473 by 78, we get 6 and a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 8156.0
Subtract 468 from 473 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
If we divide 50 by 78, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 8156.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
If we divide 500 by 78, we get 6 and a remainder of 32.
The next digit of our result is 6. 
Result so far: 8156.06
Deduct 468 from 500 and we're left 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.

On to step 9:
78 can be fit into 320 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 8156.064
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 78 fits into 80 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 8156.0641
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
78 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8156.0641
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
The number 78 fits into 200 2 times, leaving a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 8156.064102
The remainder is 44 after subtracting 156 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
When dividing 440 by 78, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 8156.0641025
Subtract 390 from 440 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
If we divide 500 by 78, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 8156.06410256
Deduct 468 from 500 and we're left 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.

The final result is 8156.06410256 with a remainder of 3.2e-08.
