98580187 ÷ 993 
Our goal is to divide 98580187 by 993.

On to step 1:
When dividing 9 by 993, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 993

Advancing to step 2:
993 goes into 98 0 times with a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Append the next digit (5) from the dividend to 98 and continue with: 985 / 993

Going ahead to step 3:
993 can be fit into 985 0 times, resulting in a remainder of 985.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 985 after subtracting 0 from 985.
Append the next digit (8) from the dividend to 985 and continue with: 9858 / 993

Step 4:
993 can be fit into 9858 9 times, resulting in a remainder of 921.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 8937 from 9858, we get 921.
Fetch the next digit (0) from the dividend, attach it to 921 and continue: 9210 / 993

Advancing to step 5:
993 goes into 9210 9 times with a remainder of 273.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtract 8937 from 9210 to get 273.
Take the next digit (1) from the dividend and append it to 273, then repeat: 2731 / 993

Advancing to step 6:
993 can be fit into 2731 2 times, resulting in a remainder of 745.
The number 2 becomes the next digit in our result. 
Result so far: 992.0
If we take 1986 away from 2731, we end up with 745.
Bring next digit (8) of the dividend behind the 745 and repeat the process: 7458 / 993

Let's proceed to step 7:
If we divide 7458 by 993, we get 7 and a remainder of 507.
Write down 7 as next digit of the result. 
Result so far: 9927.0
Subtract 6951 from 7458 to get 507.
Grab the next digit (7) from the dividend, add it to 507, then carry on: 5077 / 993

Moving on to step 8:
The number 993 fits into 5077 5 times, leaving a remainder of 112.
Use 5 as the next digit of our solution. 
Result so far: 99275.0
Subtracting 4965 from 5077 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 9:
1120 divided by 993 is 1 with a remainder of 127.
Use 1 as the next digit of our solution. 
Result so far: 99275.1
If we subtract 993 from 1120, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

On to step 10:
993 can be fit into 1270 1 times, resulting in a remainder of 277.
Put 1 as the next digit of the answer. 
Result so far: 99275.11
The remainder is 277 after subtracting 993 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Our division results in 99275.11 with a remaining 0.277.
