78186221 ÷ 585 
Our goal is to divide 78186221 by 585.

Step 1:
The number 585 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 585

Going ahead to step 2:
When dividing 78 by 585, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 585

Let's proceed to step 3:
If we divide 781 by 585, we get 1 and a remainder of 196.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 585 from 781 and we're left with 196.
Take the next digit (8) from the dividend and append it to 196, then repeat: 1968 / 585

Advancing to step 4:
When dividing 1968 by 585, we get 3 with a remainder of 213.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 1755 away from 1968, we end up with 213.
Grab the next digit (6) from the dividend, add it to 213, then carry on: 2136 / 585

Let's proceed to step 5:
When dividing 2136 by 585, we get 3 with a remainder of 381.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
Subtract 1755 from 2136 to get 381.
Bring next digit (2) of the dividend behind the 381 and repeat the process: 3812 / 585

On to step 6:
When dividing 3812 by 585, we get 6 with a remainder of 302.
Write down 6 as next digit of the result. 
Result so far: 1336.0
If we subtract 3510 from 3812, we get 302.
Bring next digit (2) of the dividend behind the 302 and repeat the process: 3022 / 585

Advancing to step 7:
The number 585 fits into 3022 5 times, leaving a remainder of 97.
Use 5 as the next digit of our solution. 
Result so far: 13365.0
If we subtract 2925 from 3022, we get 97.
Include the next digit (1) from the dividend after 97, then repeat: 971 / 585

Step 8:
When dividing 971 by 585, we get 1 with a remainder of 386.
Use 1 as the next digit of our solution. 
Result so far: 133651.0
If we subtract 585 from 971, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Let's proceed to step 9:
3860 divided by 585 is 6 with a remainder of 350.
The next digit of our result is 6. 
Result so far: 133651.6
If we take 3510 away from 3860, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 10:
When dividing 3500 by 585, we get 5 with a remainder of 575.
The number 5 becomes the next digit in our result. 
Result so far: 133651.65
If we take 2925 away from 3500, we end up with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Moving on to step 11:
The number 585 fits into 5750 9 times, leaving a remainder of 485.
Use 9 as the next digit of our solution. 
Result so far: 133651.659
Subtract 5265 from 5750 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

On to step 12:
585 goes into 4850 8 times with a remainder of 170.
Record the quotient 8 as the next digit in the result. 
Result so far: 133651.6598
Subtract 4680 from 4850 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 13:
If we divide 1700 by 585, we get 2 and a remainder of 530.
Write down 2 as next digit of the result. 
Result so far: 133651.65982
Subtracting 1170 from 1700 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 14:
5300 divided by 585 is 9 with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 133651.659829
If we take 5265 away from 5300, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 15:
If we divide 350 by 585, we get 0 and a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 133651.659829
If we take 0 away from 350, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 16:
The number 585 fits into 3500 5 times, leaving a remainder of 575.
Use 5 as the next digit of our solution. 
Result so far: 133651.65982905
If we take 2925 away from 3500, we end up with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

The quotient of the division is 133651.65982905, and the remainder is 5.75e-07.
