124942 divided by 1 
We want to figure out the number of times 124942 can be divided by 1.

Going ahead to step 1:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 1 from 1.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

On to step 2:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 2 from 2 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

On to step 3:
If we divide 4 by 1, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
If we take 4 away from 4, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Moving on to step 4:
1 goes into 9 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 1249.0
The remainder is 0 after subtracting 9 from 9.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Advancing to step 5:
1 can be fit into 4 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 12494.0
The remainder is 0 after subtracting 4 from 4.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

Moving on to step 6:
2 divided by 1 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 124942.0
The remainder is 0 after subtracting 2 from 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 124942.0
Deduct 0 from 0 and we're left 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.

Step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 124942.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 124942.0 with a remaining 0.0.
