Let's divide 761020 by 81
We want to figure out the number of times 761020 can be divided by 81.

Advancing to step 1:
81 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 81

Advancing to step 2:
When dividing 76 by 81, we get 0 with a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Append the next digit (1) from the dividend to 76 and continue with: 761 / 81

On to step 3:
The number 81 fits into 761 9 times, leaving a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 729 from 761 and we're left with 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 81

Moving on to step 4:
If we divide 320 by 81, we get 3 and a remainder of 77.
The next digit of our result is 3. 
Result so far: 93.0
If we subtract 243 from 320, we get 77.
Include the next digit (2) from the dividend after 77, then repeat: 772 / 81

Step 5:
When dividing 772 by 81, we get 9 with a remainder of 43.
The next digit of our result is 9. 
Result so far: 939.0
Deduct 729 from 772 and we're left with 43.
Take the next digit (0) from the dividend and append it to 43, then repeat: 430 / 81

Going ahead to step 6:
430 divided by 81 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 9395.0
The remainder is 25 after subtracting 405 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
81 can be fit into 250 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 9395.3
If we subtract 243 from 250, we 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.

On to step 8:
If we divide 70 by 81, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 9395.3
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
When dividing 700 by 81, we get 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 9395.308
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.

Going ahead to step 10:
The number 81 fits into 520 6 times, leaving a remainder of 34.
The next digit of our result is 6. 
Result so far: 9395.3086
If we take 486 away from 520, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 11:
The number 81 fits into 340 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 9395.30864
If we take 324 away from 340, we end up 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.

Advancing to step 12:
81 can be fit into 160 1 times, resulting in a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 9395.308641
Deduct 81 from 160 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 13:
790 divided by 81 is 9 with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 9395.3086419
Subtracting 729 from 790 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 14:
The number 81 fits into 610 7 times, leaving a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 9395.30864197
Subtract 567 from 610 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

After the division, we end up with 9395.30864197 and a remainder of 4.3e-08.
