139943 divided by 76 
We want to figure out the number of times 139943 can be divided by 76.

Moving on to step 1:
When dividing 1 by 76, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 76

On to step 2:
76 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 76

Let's proceed to step 3:
139 divided by 76 is 1 with a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 76 from 139, we get 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 76

Let's proceed to step 4:
76 goes into 639 8 times with a remainder of 31.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 608 from 639 to get 31.
Fetch the next digit (4) from the dividend, attach it to 31 and continue: 314 / 76

Step 5:
76 goes into 314 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 184.0
Subtracting 304 from 314 leaves us with 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 76

Moving on to step 6:
If we divide 103 by 76, we get 1 and a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1841.0
If we take 76 away from 103, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
The number 76 fits into 270 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 1841.3
Deduct 228 from 270 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
76 goes into 420 5 times with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 1841.35
Subtracting 380 from 420 leaves us 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.

Moving on to step 9:
76 goes into 400 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 1841.355
If we subtract 380 from 400, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 1841.355 with a remaining 0.002.
