We divide 138229 by 81
We want to figure out the number of times 138229 can be divided by 81.

Let's proceed to step 1:
1 divided by 81 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 81

Going ahead to step 2:
81 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 81

On to step 3:
138 divided by 81 is 1 with a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 81 from 138 leaves us with 57.
Grab the next digit (2) from the dividend, add it to 57, then carry on: 572 / 81

Let's proceed to step 4:
When dividing 572 by 81, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 17.0
If we take 567 away from 572, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 81

On to step 5:
The number 81 fits into 52 0 times, leaving a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
Subtracting 0 from 52 leaves us with 52.
Include the next digit (9) from the dividend after 52, then repeat: 529 / 81

Advancing to step 6:
The number 81 fits into 529 6 times, leaving a remainder of 43.
Use 6 as the next digit of our solution. 
Result so far: 1706.0
The remainder is 43 after subtracting 486 from 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
The number 81 fits into 430 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 1706.5
If we take 405 away from 430, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
81 goes into 250 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 1706.53
Subtract 243 from 250 to 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 9:
70 divided by 81 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 1706.53
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
81 can be fit into 700 8 times, resulting in a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 1706.5308
Subtracting 648 from 700 leaves us 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.

On to step 11:
81 can be fit into 520 6 times, resulting in a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 1706.53086
Subtracting 486 from 520 leaves us 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.

Advancing to step 12:
340 divided by 81 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 1706.530864
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.

On to step 13:
When dividing 160 by 81, we get 1 with a remainder of 79.
The next digit of our result is 1. 
Result so far: 1706.5308641
The remainder is 79 after subtracting 81 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 14:
81 goes into 790 9 times with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 1706.53086419
Subtract 729 from 790 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Our division results in 1706.53086419 with a remaining 6.1e-08.
