9860021 ÷ 589 
Our goal is to divide 9860021 by 589.

Let's proceed to step 1:
589 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 589

Moving on to step 2:
When dividing 98 by 589, we get 0 with a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 98 and we're left with 98.
Bring next digit (6) of the dividend behind the 98 and repeat the process: 986 / 589

Advancing to step 3:
589 goes into 986 1 times with a remainder of 397.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 589 from 986 and we're left with 397.
Bring next digit (0) of the dividend behind the 397 and repeat the process: 3970 / 589

Advancing to step 4:
The number 589 fits into 3970 6 times, leaving a remainder of 436.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 3534 from 3970 leaves us with 436.
Take the next digit (0) from the dividend and append it to 436, then repeat: 4360 / 589

Let's proceed to step 5:
4360 divided by 589 is 7 with a remainder of 237.
The number 7 becomes the next digit in our result. 
Result so far: 167.0
Subtracting 4123 from 4360 leaves us with 237.
Append the next digit (2) from the dividend to 237 and continue with: 2372 / 589

Step 6:
589 can be fit into 2372 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 1674.0
Subtract 2356 from 2372 to get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 589

Advancing to step 7:
If we divide 161 by 589, we get 0 and a remainder of 161.
Write down 0 as next digit of the result. 
Result so far: 16740.0
Subtracting 0 from 161 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Advancing to step 8:
589 can be fit into 1610 2 times, resulting in a remainder of 432.
Record the quotient 2 as the next digit in the result. 
Result so far: 16740.2
Subtract 1178 from 1610 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 9:
589 can be fit into 4320 7 times, resulting in a remainder of 197.
Put 7 as the next digit of the answer. 
Result so far: 16740.27
Subtract 4123 from 4320 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 10:
1970 divided by 589 is 3 with a remainder of 203.
Put 3 as the next digit of the answer. 
Result so far: 16740.273
If we subtract 1767 from 1970, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Moving on to step 11:
589 can be fit into 2030 3 times, resulting in a remainder of 263.
The next digit of our result is 3. 
Result so far: 16740.2733
If we subtract 1767 from 2030, we get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Our division results in 16740.2733 with a remaining 0.00263.
