161490 divided by 81 
We want to figure out the number of times 161490 can be divided by 81.

Let's proceed to step 1:
81 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 81

Advancing to step 2:
When dividing 16 by 81, we get 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 81

Step 3:
81 can be fit into 161 1 times, resulting in a remainder of 80.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 81 from 161 leaves us with 80.
Grab the next digit (4) from the dividend, add it to 80, then carry on: 804 / 81

Going ahead to step 4:
When dividing 804 by 81, we get 9 with a remainder of 75.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we subtract 729 from 804, we get 75.
Bring next digit (9) of the dividend behind the 75 and repeat the process: 759 / 81

Moving on to step 5:
759 divided by 81 is 9 with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 199.0
The remainder is 30 after subtracting 729 from 759.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 81

Going ahead to step 6:
If we divide 300 by 81, we get 3 and a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 1993.0
If we subtract 243 from 300, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 7:
When dividing 570 by 81, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 1993.7
Deduct 567 from 570 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
The number 81 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1993.7
Deduct 0 from 30 and we're left 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 9:
If we divide 300 by 81, we get 3 and a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 1993.703
If we take 243 away from 300, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 10:
If we divide 570 by 81, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 1993.7037
If we take 567 away from 570, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
When dividing 30 by 81, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 1993.7037
Deduct 0 from 30 and we're left 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.

Step 12:
81 goes into 300 3 times with a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 1993.703703
Subtracting 243 from 300 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 13:
The number 81 fits into 570 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 1993.7037037
Subtract 567 from 570 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 14:
If we divide 30 by 81, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1993.7037037
Deduct 0 from 30 and we're left 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.

In conclusion, the division gives 1993.7037037 with a balance of 3e-08.
