138948 divided by 75 
We're looking to find how many times 75 goes into 138948.

Step 1:
75 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 75

On to step 2:
If we divide 13 by 75, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 75

On to step 3:
The number 75 fits into 138 1 times, leaving a remainder of 63.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 75 from 138 and we're left with 63.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 75

Moving on to step 4:
When dividing 639 by 75, we get 8 with a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 600 from 639 to get 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 75

Going ahead to step 5:
75 goes into 394 5 times with a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 185.0
Subtract 375 from 394 to get 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 75

Advancing to step 6:
The number 75 fits into 198 2 times, leaving a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 1852.0
Subtract 150 from 198 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
75 can be fit into 480 6 times, resulting in a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 1852.6
The remainder is 30 after subtracting 450 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
75 can be fit into 300 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 1852.64
The remainder is 0 after subtracting 300 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
75 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1852.64
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
0 divided by 75 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1852.64
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 1852.64 and a remainder of 0.0.
