82186643 ÷ 161 
Let's see how many times 161 fits into 82186643.

On to step 1:
161 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
If we take 0 away from 8, we end up with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 161

Going ahead to step 2:
When dividing 82 by 161, we get 0 with a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Include the next digit (1) from the dividend after 82, then repeat: 821 / 161

On to step 3:
The number 161 fits into 821 5 times, leaving a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 16 after subtracting 805 from 821.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 161

Going ahead to step 4:
168 divided by 161 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Deduct 161 from 168 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 161

Advancing to step 5:
When dividing 76 by 161, we get 0 with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 510.0
Deduct 0 from 76 and we're left with 76.
Bring next digit (6) of the dividend behind the 76 and repeat the process: 766 / 161

On to step 6:
161 goes into 766 4 times with a remainder of 122.
Put 4 as the next digit of the answer. 
Result so far: 5104.0
Subtracting 644 from 766 leaves us with 122.
Fetch the next digit (4) from the dividend, attach it to 122 and continue: 1224 / 161

Step 7:
The number 161 fits into 1224 7 times, leaving a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 51047.0
If we take 1127 away from 1224, we end up with 97.
Bring next digit (3) of the dividend behind the 97 and repeat the process: 973 / 161

Going ahead to step 8:
973 divided by 161 is 6 with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 510476.0
Subtract 966 from 973 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
161 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 510476.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
700 divided by 161 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 510476.04
Deduct 644 from 700 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
161 goes into 560 3 times with a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 510476.043
Subtract 483 from 560 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 12:
770 divided by 161 is 4 with a remainder of 126.
Write down 4 as next digit of the result. 
Result so far: 510476.0434
If we subtract 644 from 770, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 13:
If we divide 1260 by 161, we get 7 and a remainder of 133.
Write down 7 as next digit of the result. 
Result so far: 510476.04347
If we subtract 1127 from 1260, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 14:
When dividing 1330 by 161, we get 8 with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 510476.043478
Subtract 1288 from 1330 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 15:
161 goes into 420 2 times with a remainder of 98.
Put 2 as the next digit of the answer. 
Result so far: 510476.0434782
If we subtract 322 from 420, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 16:
The number 161 fits into 980 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 510476.04347826
Subtract 966 from 980 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 510476.04347826, and the remainder is 1.4e-08.
