80186163 ÷ 987 
Our goal is to divide 80186163 by 987.

Advancing to step 1:
When dividing 8 by 987, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 987

Step 2:
987 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (1) of the dividend behind the 80 and repeat the process: 801 / 987

Advancing to step 3:
If we divide 801 by 987, we get 0 and a remainder of 801.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 801, we end up with 801.
Fetch the next digit (8) from the dividend, attach it to 801 and continue: 8018 / 987

Step 4:
If we divide 8018 by 987, we get 8 and a remainder of 122.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 7896 from 8018, we get 122.
Fetch the next digit (6) from the dividend, attach it to 122 and continue: 1226 / 987

Step 5:
If we divide 1226 by 987, we get 1 and a remainder of 239.
Write down 1 as next digit of the result. 
Result so far: 81.0
The remainder is 239 after subtracting 987 from 1226.
Grab the next digit (1) from the dividend, add it to 239, then carry on: 2391 / 987

Let's proceed to step 6:
When dividing 2391 by 987, we get 2 with a remainder of 417.
Record the quotient 2 as the next digit in the result. 
Result so far: 812.0
Deduct 1974 from 2391 and we're left with 417.
Include the next digit (6) from the dividend after 417, then repeat: 4176 / 987

Let's proceed to step 7:
The number 987 fits into 4176 4 times, leaving a remainder of 228.
Put 4 as the next digit of the answer. 
Result so far: 8124.0
The remainder is 228 after subtracting 3948 from 4176.
Include the next digit (3) from the dividend after 228, then repeat: 2283 / 987

Step 8:
When dividing 2283 by 987, we get 2 with a remainder of 309.
Record the quotient 2 as the next digit in the result. 
Result so far: 81242.0
Subtract 1974 from 2283 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Step 9:
3090 divided by 987 is 3 with a remainder of 129.
Record the quotient 3 as the next digit in the result. 
Result so far: 81242.3
The remainder is 129 after subtracting 2961 from 3090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Going ahead to step 10:
1290 divided by 987 is 1 with a remainder of 303.
Use 1 as the next digit of our solution. 
Result so far: 81242.31
If we take 987 away from 1290, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Going ahead to step 11:
If we divide 3030 by 987, we get 3 and a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 81242.313
The remainder is 69 after subtracting 2961 from 3030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 12:
987 goes into 690 0 times with a remainder of 690.
Write down 0 as next digit of the result. 
Result so far: 81242.313
If we subtract 0 from 690, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Going ahead to step 13:
If we divide 6900 by 987, we get 6 and a remainder of 978.
Put 6 as the next digit of the answer. 
Result so far: 81242.31306
The remainder is 978 after subtracting 5922 from 6900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9780, and continue the process.

Going ahead to step 14:
When dividing 9780 by 987, we get 9 with a remainder of 897.
Use 9 as the next digit of our solution. 
Result so far: 81242.313069
If we subtract 8883 from 9780, we get 897.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8970, and continue the process.

Step 15:
8970 divided by 987 is 9 with a remainder of 87.
Put 9 as the next digit of the answer. 
Result so far: 81242.3130699
The remainder is 87 after subtracting 8883 from 8970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

In conclusion, the division gives 81242.3130699 with a balance of 8.7e-07.
