Let's divide 753944 by 81
We want to figure out the number of times 753944 can be divided by 81.

Moving on to step 1:
7 divided by 81 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 81

On to step 2:
When dividing 75 by 81, we get 0 with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Grab the next digit (3) from the dividend, add it to 75, then carry on: 753 / 81

Moving on to step 3:
When dividing 753 by 81, we get 9 with a remainder of 24.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 729 from 753, we get 24.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 81

Step 4:
When dividing 249 by 81, we get 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 93.0
Deduct 243 from 249 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 81

On to step 5:
If we divide 64 by 81, we get 0 and a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 930.0
Deduct 0 from 64 and we're left with 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 81

On to step 6:
When dividing 644 by 81, we get 7 with a remainder of 77.
The next digit of our result is 7. 
Result so far: 9307.0
If we take 567 away from 644, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 7:
The number 81 fits into 770 9 times, leaving a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 9307.9
Deduct 729 from 770 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 8:
The number 81 fits into 410 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 9307.95
If we take 405 away from 410, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
When dividing 50 by 81, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 9307.95
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
The number 81 fits into 500 6 times, leaving a remainder of 14.
The next digit of our result is 6. 
Result so far: 9307.9506
If we take 486 away from 500, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
When dividing 140 by 81, we get 1 with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 9307.95061
Subtract 81 from 140 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 12:
81 goes into 590 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 9307.950617
Subtract 567 from 590 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 13:
230 divided by 81 is 2 with a remainder of 68.
The next digit of our result is 2. 
Result so far: 9307.9506172
If we subtract 162 from 230, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 14:
If we divide 680 by 81, we get 8 and a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 9307.95061728
If we subtract 648 from 680, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 9307.95061728 and a remainder of 3.2e-08.
