749976 divided by 42 
We want to divide 749976 by 42.

Step 1:
The number 42 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 42

Moving on to step 2:
When dividing 74 by 42, we get 1 with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 42 from 74, we get 32.
Include the next digit (9) from the dividend after 32, then repeat: 329 / 42

Let's proceed to step 3:
42 goes into 329 7 times with a remainder of 35.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 294 from 329, we get 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 42

Step 4:
359 divided by 42 is 8 with a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
If we take 336 away from 359, we end up with 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 42

Let's proceed to step 5:
When dividing 237 by 42, we get 5 with a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 1785.0
If we subtract 210 from 237, we get 27.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 42

On to step 6:
276 divided by 42 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 17856.0
If we subtract 252 from 276, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 17856.5
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 17856.57
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
When dividing 60 by 42, we get 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 17856.571
Subtract 42 from 60 to get 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 10:
If we divide 180 by 42, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 17856.5714
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
120 divided by 42 is 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 17856.57142
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.

Let's proceed to step 12:
42 goes into 360 8 times with a remainder of 24.
The next digit of our result is 8. 
Result so far: 17856.571428
If we take 336 away from 360, we end up 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 13:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 17856.5714285
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.

On to step 14:
When dividing 300 by 42, we get 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 17856.57142857
Subtracting 294 from 300 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 17856.57142857, and the remainder is 6e-09.
