We look at the division of 112138 by 81 
Let's see how many times 81 fits into 112138.

Let's proceed to step 1:
When dividing 1 by 81, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 81

On to step 2:
81 can be fit into 11 0 times, resulting in a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 81

Let's proceed to step 3:
112 divided by 81 is 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 81 from 112 leaves us with 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 81

Moving on to step 4:
81 goes into 311 3 times with a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 243 from 311 to get 68.
Append the next digit (3) from the dividend to 68 and continue with: 683 / 81

On to step 5:
81 can be fit into 683 8 times, resulting in a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 138.0
Subtract 648 from 683 to get 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 81

Moving on to step 6:
358 divided by 81 is 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 1384.0
Subtracting 324 from 358 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.

Going ahead to step 7:
340 divided by 81 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1384.4
Deduct 324 from 340 and we're left 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.

Step 8:
When dividing 160 by 81, we get 1 with a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 1384.41
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.

Step 9:
81 goes into 790 9 times with a remainder of 61.
The next digit of our result is 9. 
Result so far: 1384.419
If we take 729 away from 790, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 10:
If we divide 610 by 81, we get 7 and a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 1384.4197
If we subtract 567 from 610, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 11:
81 can be fit into 430 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 1384.41975
If we subtract 405 from 430, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
The number 81 fits into 250 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 1384.419753
Subtracting 243 from 250 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 13:
81 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 1384.419753
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
81 can be fit into 700 8 times, resulting in a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 1384.41975308
Deduct 648 from 700 and we're left 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.

The quotient of the division is 1384.41975308, and the remainder is 5.2e-08.
