We divide 139538 by 51
We want to figure out the number of times 139538 can be divided by 51.

Going ahead to step 1:
The number 51 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 51

Let's proceed to step 2:
The number 51 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 51

Let's proceed to step 3:
When dividing 139 by 51, we get 2 with a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 102 from 139 to get 37.
Take the next digit (5) from the dividend and append it to 37, then repeat: 375 / 51

On to step 4:
375 divided by 51 is 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we take 357 away from 375, we end up with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 51

On to step 5:
When dividing 183 by 51, we get 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 273.0
If we subtract 153 from 183, we get 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 51

Step 6:
308 divided by 51 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 2736.0
Subtract 306 from 308 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
If we divide 20 by 51, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2736.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
If we divide 200 by 51, we get 3 and a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 2736.03
If we take 153 away from 200, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 9:
When dividing 470 by 51, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 2736.039
Subtracting 459 from 470 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
51 can be fit into 110 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2736.0392
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
51 goes into 80 1 times with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 2736.03921
If we subtract 51 from 80, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 12:
When dividing 290 by 51, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 2736.039215
The remainder is 35 after subtracting 255 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
The number 51 fits into 350 6 times, leaving a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 2736.0392156
If we subtract 306 from 350, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
If we divide 440 by 51, we get 8 and a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 2736.03921568
The remainder is 32 after subtracting 408 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 2736.03921568 with a remainder of 3.2e-08.
