We divide 137433 by 81
We want to figure out the number of times 137433 can be divided by 81.

Moving on to step 1:
1 divided by 81 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 81

Step 2:
13 divided by 81 is 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 81

Step 3:
If we divide 137 by 81, we get 1 and a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 81 from 137 leaves us with 56.
Include the next digit (4) from the dividend after 56, then repeat: 564 / 81

Advancing to step 4:
When dividing 564 by 81, we get 6 with a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 486 from 564, we get 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 81

On to step 5:
The number 81 fits into 783 9 times, leaving a remainder of 54.
The next digit of our result is 9. 
Result so far: 169.0
If we subtract 729 from 783, we get 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 81

Going ahead to step 6:
If we divide 543 by 81, we get 6 and a remainder of 57.
The next digit of our result is 6. 
Result so far: 1696.0
Subtracting 486 from 543 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.

Let's proceed to step 7:
The number 81 fits into 570 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 1696.7
The remainder is 3 after subtracting 567 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
If we divide 30 by 81, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1696.7
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:
81 goes into 300 3 times with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 1696.703
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.

On to step 10:
When dividing 570 by 81, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 1696.7037
If we subtract 567 from 570, we 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.

Advancing to step 11:
If we divide 30 by 81, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 1696.7037
If we take 0 away from 30, we end up 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.

Advancing to step 12:
81 can be fit into 300 3 times, resulting in a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 1696.703703
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.

Step 13:
81 goes into 570 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 1696.7037037
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.

Step 14:
30 divided by 81 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1696.7037037
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.

After the division, we end up with 1696.7037037 and a remainder of 3e-08.
