749886 ÷ 42 
Our goal is to divide 749886 by 42.

Moving on to step 1:
If we divide 7 by 42, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 42

On to step 2:
When dividing 74 by 42, we get 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
If we take 42 away from 74, we end up with 32.
Include the next digit (9) from the dividend after 32, then repeat: 329 / 42

Let's proceed to step 3:
42 can be fit into 329 7 times, resulting in a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 35 after subtracting 294 from 329.
Bring next digit (8) of the dividend behind the 35 and repeat the process: 358 / 42

On to step 4:
When dividing 358 by 42, we get 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 178.0
Subtracting 336 from 358 leaves us with 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 42

Step 5:
When dividing 228 by 42, we get 5 with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 1785.0
Subtract 210 from 228 to get 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 42

Let's proceed to step 6:
186 divided by 42 is 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 17854.0
Deduct 168 from 186 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
42 goes into 180 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 17854.4
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
If we divide 120 by 42, we get 2 and a remainder of 36.
The next digit of our result is 2. 
Result so far: 17854.42
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
42 can be fit into 360 8 times, resulting in a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 17854.428
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
240 divided by 42 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 17854.4285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
42 goes into 300 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 17854.42857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
60 divided by 42 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 17854.428571
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
When dividing 180 by 42, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 17854.4285714
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
42 goes into 120 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 17854.42857142
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 17854.42857142, and the remainder is 3.6e-08.
