We look at the division of 71139 by 49 
We want to figure out the number of times 71139 can be divided by 49.

Step 1:
The number 49 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 49

On to step 2:
The number 49 fits into 71 1 times, leaving a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 49 from 71, we get 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 49

Let's proceed to step 3:
The number 49 fits into 221 4 times, leaving a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 196 from 221, we get 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 49

Moving on to step 4:
49 goes into 253 5 times with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 145.0
The remainder is 8 after subtracting 245 from 253.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 49

On to step 5:
The number 49 fits into 89 1 times, leaving a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 1451.0
If we take 49 away from 89, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 6:
49 can be fit into 400 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 1451.8
Subtract 392 from 400 to 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.

Moving on to step 7:
49 can be fit into 80 1 times, resulting in a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1451.81
Subtract 49 from 80 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 8:
49 goes into 310 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 1451.816
The remainder is 16 after subtracting 294 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
49 can be fit into 160 3 times, resulting in a remainder of 13.
The next digit of our result is 3. 
Result so far: 1451.8163
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 10:
When dividing 130 by 49, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 1451.81632
Deduct 98 from 130 and we're left 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.

Advancing to step 11:
49 goes into 320 6 times with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 1451.816326
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
260 divided by 49 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1451.8163265
The remainder is 15 after subtracting 245 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
The number 49 fits into 150 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 1451.81632653
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 1451.81632653 with a remaining 3e-09.
