120370 divided by 81 
We want to figure out the number of times 120370 can be divided by 81.

On to step 1:
81 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 81

Step 2:
81 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 81

Step 3:
81 goes into 120 1 times with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 81 from 120, we get 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 81

Step 4:
The number 81 fits into 393 4 times, leaving a remainder of 69.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 324 away from 393, we end up with 69.
Bring next digit (7) of the dividend behind the 69 and repeat the process: 697 / 81

Step 5:
81 can be fit into 697 8 times, resulting in a remainder of 49.
Use 8 as the next digit of our solution. 
Result so far: 148.0
If we subtract 648 from 697, we get 49.
Fetch the next digit (0) from the dividend, attach it to 49 and continue: 490 / 81

Going ahead to step 6:
490 divided by 81 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 1486.0
Deduct 486 from 490 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
The number 81 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1486.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
When dividing 400 by 81, we get 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 1486.04
If we take 324 away from 400, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 9:
760 divided by 81 is 9 with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 1486.049
The remainder is 31 after subtracting 729 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 10:
310 divided by 81 is 3 with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 1486.0493
Subtracting 243 from 310 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 11:
When dividing 670 by 81, we get 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 1486.04938
Subtract 648 from 670 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
81 can be fit into 220 2 times, resulting in a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 1486.049382
Deduct 162 from 220 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 13:
580 divided by 81 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 1486.0493827
If we take 567 away from 580, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 14:
When dividing 130 by 81, we get 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 1486.04938271
Subtract 81 from 130 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

After the division, we end up with 1486.04938271 and a remainder of 4.9e-08.
