Let's divide 690082 by 81
We're looking to find how many times 81 goes into 690082.

Let's proceed to step 1:
If we divide 6 by 81, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 81

Let's proceed to step 2:
When dividing 69 by 81, we get 0 with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Bring next digit (0) of the dividend behind the 69 and repeat the process: 690 / 81

Moving on to step 3:
The number 81 fits into 690 8 times, leaving a remainder of 42.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 42 after subtracting 648 from 690.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 81

Advancing to step 4:
81 can be fit into 420 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 85.0
Subtracting 405 from 420 leaves us with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 81

Step 5:
If we divide 158 by 81, we get 1 and a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 851.0
If we take 81 away from 158, we end up with 77.
Append the next digit (2) from the dividend to 77 and continue with: 772 / 81

Step 6:
772 divided by 81 is 9 with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 8519.0
Deduct 729 from 772 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
430 divided by 81 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 8519.5
If we take 405 away from 430, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
250 divided by 81 is 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 8519.53
Subtract 243 from 250 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.

Going ahead to step 9:
The number 81 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 8519.53
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
If we divide 700 by 81, we get 8 and a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 8519.5308
If we take 648 away from 700, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
When dividing 520 by 81, we get 6 with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 8519.53086
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 12:
The number 81 fits into 340 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 8519.530864
Deduct 324 from 340 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
The number 81 fits into 160 1 times, leaving a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 8519.5308641
If we subtract 81 from 160, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 14:
790 divided by 81 is 9 with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 8519.53086419
The remainder is 61 after subtracting 729 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

After the division, we end up with 8519.53086419 and a remainder of 6.1e-08.
