Let's divide 21860158 by 584
Our goal is to divide 21860158 by 584.

Advancing to step 1:
584 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 584

Advancing to step 2:
The number 584 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 584

Moving on to step 3:
If we divide 218 by 584, we get 0 and a remainder of 218.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 218, we end up with 218.
Bring next digit (6) of the dividend behind the 218 and repeat the process: 2186 / 584

On to step 4:
584 can be fit into 2186 3 times, resulting in a remainder of 434.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1752 from 2186 and we're left with 434.
Bring next digit (0) of the dividend behind the 434 and repeat the process: 4340 / 584

Step 5:
When dividing 4340 by 584, we get 7 with a remainder of 252.
The next digit of our result is 7. 
Result so far: 37.0
If we take 4088 away from 4340, we end up with 252.
Take the next digit (1) from the dividend and append it to 252, then repeat: 2521 / 584

Moving on to step 6:
The number 584 fits into 2521 4 times, leaving a remainder of 185.
The number 4 becomes the next digit in our result. 
Result so far: 374.0
Deduct 2336 from 2521 and we're left with 185.
Take the next digit (5) from the dividend and append it to 185, then repeat: 1855 / 584

Step 7:
584 goes into 1855 3 times with a remainder of 103.
Record the quotient 3 as the next digit in the result. 
Result so far: 3743.0
If we take 1752 away from 1855, we end up with 103.
Fetch the next digit (8) from the dividend, attach it to 103 and continue: 1038 / 584

Step 8:
The number 584 fits into 1038 1 times, leaving a remainder of 454.
The number 1 becomes the next digit in our result. 
Result so far: 37431.0
If we take 584 away from 1038, we end up with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Step 9:
584 goes into 4540 7 times with a remainder of 452.
The number 7 becomes the next digit in our result. 
Result so far: 37431.7
Subtract 4088 from 4540 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Let's proceed to step 10:
584 can be fit into 4520 7 times, resulting in a remainder of 432.
Write down 7 as next digit of the result. 
Result so far: 37431.77
Deduct 4088 from 4520 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

After the division, we end up with 37431.77 and a remainder of 0.432.
