137993 divided by 81 
Let's see how many times 81 fits into 137993.

Moving on to step 1:
If we divide 1 by 81, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 81

Let's proceed to step 2:
If we divide 13 by 81, we get 0 and 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.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 81

Moving on to step 3:
If we divide 137 by 81, we get 1 and a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 81 from 137 and we're left with 56.
Fetch the next digit (9) from the dividend, attach it to 56 and continue: 569 / 81

Moving on to step 4:
The number 81 fits into 569 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 2 after subtracting 567 from 569.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 81

Step 5:
81 goes into 29 0 times with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 170.0
Subtracting 0 from 29 leaves us with 29.
Include the next digit (3) from the dividend after 29, then repeat: 293 / 81

Moving on to step 6:
The number 81 fits into 293 3 times, leaving a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 1703.0
If we take 243 away from 293, 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 7:
If we divide 500 by 81, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 1703.6
Subtract 486 from 500 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
If we divide 140 by 81, we get 1 and a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 1703.61
Subtracting 81 from 140 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 9:
590 divided by 81 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 1703.617
If we take 567 away from 590, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
81 can be fit into 230 2 times, resulting in a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 1703.6172
Subtract 162 from 230 to 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.

Advancing to step 11:
81 goes into 680 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 1703.61728
If we take 648 away from 680, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
81 can be fit into 320 3 times, resulting in a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 1703.617283
If we take 243 away from 320, 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 13:
When dividing 770 by 81, we get 9 with a remainder of 41.
The next digit of our result is 9. 
Result so far: 1703.6172839
If we subtract 729 from 770, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 14:
The number 81 fits into 410 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1703.61728395
Subtract 405 from 410 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 1703.61728395 with a balance of 5e-09.
