We look at the division of 81033512 by 139 
Our goal is to divide 81033512 by 139.

Advancing to step 1:
If we divide 8 by 139, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 139

Step 2:
If we divide 81 by 139, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 139

Moving on to step 3:
810 divided by 139 is 5 with a remainder of 115.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 115 after subtracting 695 from 810.
Grab the next digit (3) from the dividend, add it to 115, then carry on: 1153 / 139

Moving on to step 4:
The number 139 fits into 1153 8 times, leaving a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 58.0
If we take 1112 away from 1153, we end up with 41.
Include the next digit (3) from the dividend after 41, then repeat: 413 / 139

Going ahead to step 5:
139 can be fit into 413 2 times, resulting in a remainder of 135.
Write down 2 as next digit of the result. 
Result so far: 582.0
Deduct 278 from 413 and we're left with 135.
Fetch the next digit (5) from the dividend, attach it to 135 and continue: 1355 / 139

Going ahead to step 6:
When dividing 1355 by 139, we get 9 with a remainder of 104.
Record the quotient 9 as the next digit in the result. 
Result so far: 5829.0
Subtracting 1251 from 1355 leaves us with 104.
Take the next digit (1) from the dividend and append it to 104, then repeat: 1041 / 139

On to step 7:
139 can be fit into 1041 7 times, resulting in a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 58297.0
If we take 973 away from 1041, we end up with 68.
Fetch the next digit (2) from the dividend, attach it to 68 and continue: 682 / 139

Moving on to step 8:
If we divide 682 by 139, we get 4 and a remainder of 126.
Put 4 as the next digit of the answer. 
Result so far: 582974.0
If we subtract 556 from 682, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 9:
139 goes into 1260 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 582974.9
If we take 1251 away from 1260, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
The number 139 fits into 90 0 times, leaving a remainder of 90.
The next digit of our result is 0. 
Result so far: 582974.9
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 11:
139 goes into 900 6 times with a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 582974.906
Subtracting 834 from 900 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 12:
139 can be fit into 660 4 times, resulting in a remainder of 104.
Put 4 as the next digit of the answer. 
Result so far: 582974.9064
Subtracting 556 from 660 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 13:
139 can be fit into 1040 7 times, resulting in a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 582974.90647
If we subtract 973 from 1040, we get 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 14:
670 divided by 139 is 4 with a remainder of 114.
The next digit of our result is 4. 
Result so far: 582974.906474
The remainder is 114 after subtracting 556 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 15:
The number 139 fits into 1140 8 times, leaving a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 582974.9064748
Subtracting 1112 from 1140 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 16:
139 goes into 280 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 582974.90647482
If we take 278 away from 280, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 582974.90647482 with a remaining 2e-09.
