139550 ÷ 72 
Let's see how many times 72 fits into 139550.

Moving on to step 1:
If we divide 1 by 72, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 72

Moving on to step 2:
72 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 72

Going ahead to step 3:
If we divide 139 by 72, we get 1 and a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 72 from 139, we get 67.
Grab the next digit (5) from the dividend, add it to 67, then carry on: 675 / 72

Going ahead to step 4:
72 goes into 675 9 times with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 648 from 675 and we're left with 27.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 72

Going ahead to step 5:
275 divided by 72 is 3 with a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 193.0
If we take 216 away from 275, we end up with 59.
Fetch the next digit (0) from the dividend, attach it to 59 and continue: 590 / 72

Going ahead to step 6:
590 divided by 72 is 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 1938.0
Deduct 576 from 590 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
When dividing 140 by 72, we get 1 with a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 1938.1
If we subtract 72 from 140, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 8:
The number 72 fits into 680 9 times, leaving a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 1938.19
If we take 648 away from 680, we end up 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 9:
The number 72 fits into 320 4 times, leaving a remainder of 32.
The next digit of our result is 4. 
Result so far: 1938.194
Subtract 288 from 320 to get 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 10:
72 can be fit into 320 4 times, resulting in a remainder of 32.
The next digit of our result is 4. 
Result so far: 1938.1944
Subtracting 288 from 320 leaves us 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.

The final outcome is 1938.1944, with a leftover of 0.00032.
