81291384 ÷ 186 
Our goal is to divide 81291384 by 186.

Step 1:
186 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 186

Going ahead to step 2:
81 divided by 186 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Fetch the next digit (2) from the dividend, attach it to 81 and continue: 812 / 186

Moving on to step 3:
The number 186 fits into 812 4 times, leaving a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 744 away from 812, we end up with 68.
Fetch the next digit (9) from the dividend, attach it to 68 and continue: 689 / 186

Let's proceed to step 4:
If we divide 689 by 186, we get 3 and a remainder of 131.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we subtract 558 from 689, we get 131.
Take the next digit (1) from the dividend and append it to 131, then repeat: 1311 / 186

Let's proceed to step 5:
186 goes into 1311 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 437.0
If we subtract 1302 from 1311, we get 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 186

Going ahead to step 6:
93 divided by 186 is 0 with a remainder of 93.
Write down 0 as next digit of the result. 
Result so far: 4370.0
Subtracting 0 from 93 leaves us with 93.
Take the next digit (8) from the dividend and append it to 93, then repeat: 938 / 186

Going ahead to step 7:
When dividing 938 by 186, we get 5 with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 43705.0
The remainder is 8 after subtracting 930 from 938.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 186

Step 8:
84 divided by 186 is 0 with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 437050.0
Subtracting 0 from 84 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 9:
186 goes into 840 4 times with a remainder of 96.
The next digit of our result is 4. 
Result so far: 437050.4
Subtract 744 from 840 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 10:
186 can be fit into 960 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 437050.45
If we take 930 away from 960, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
300 divided by 186 is 1 with a remainder of 114.
The next digit of our result is 1. 
Result so far: 437050.451
Deduct 186 from 300 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 12:
186 can be fit into 1140 6 times, resulting in a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 437050.4516
If we take 1116 away from 1140, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
240 divided by 186 is 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 437050.45161
If we take 186 away from 240, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 14:
186 goes into 540 2 times with a remainder of 168.
The number 2 becomes the next digit in our result. 
Result so far: 437050.451612
If we subtract 372 from 540, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 15:
186 goes into 1680 9 times with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 437050.4516129
If we subtract 1674 from 1680, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 16:
When dividing 60 by 186, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 437050.4516129
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 437050.4516129, and the remainder is 6e-08.
