We're dividing 749778 by 42 
We want to figure out the number of times 749778 can be divided by 42.

Step 1:
When dividing 7 by 42, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 42

Advancing to step 2:
When dividing 74 by 42, we get 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 42 from 74 and we're left with 32.
Take the next digit (9) from the dividend and append it to 32, then repeat: 329 / 42

Moving on to step 3:
42 can be fit into 329 7 times, resulting in a remainder of 35.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 294 from 329 to get 35.
Append the next digit (7) from the dividend to 35 and continue with: 357 / 42

Let's proceed to step 4:
42 goes into 357 8 times with a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 178.0
If we take 336 away from 357, we end up with 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 42

Going ahead to step 5:
The number 42 fits into 217 5 times, leaving a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 1785.0
If we subtract 210 from 217, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 42

Advancing to step 6:
42 can be fit into 78 1 times, resulting in a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 17851.0
The remainder is 36 after subtracting 42 from 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
360 divided by 42 is 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 17851.8
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
If we divide 240 by 42, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 17851.85
If we take 210 away from 240, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
If we divide 300 by 42, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 17851.857
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
When dividing 60 by 42, we get 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 17851.8571
Subtracting 42 from 60 leaves us 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 11:
180 divided by 42 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 17851.85714
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.

Let's proceed to step 12:
If we divide 120 by 42, we get 2 and a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 17851.857142
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
42 goes into 360 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 17851.8571428
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
42 can be fit into 240 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 17851.85714285
If we take 210 away from 240, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 17851.85714285 with a balance of 3e-08.
