42759042 ÷ 402 
We want to divide 42759042 by 402.

Going ahead to step 1:
402 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 402

Going ahead to step 2:
If we divide 42 by 402, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (7) from the dividend to 42 and continue with: 427 / 402

Let's proceed to step 3:
The number 402 fits into 427 1 times, leaving a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 25 after subtracting 402 from 427.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 402

Advancing to step 4:
255 divided by 402 is 0 with a remainder of 255.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 255 to get 255.
Append the next digit (9) from the dividend to 255 and continue with: 2559 / 402

Moving on to step 5:
The number 402 fits into 2559 6 times, leaving a remainder of 147.
Use 6 as the next digit of our solution. 
Result so far: 106.0
If we take 2412 away from 2559, we end up with 147.
Take the next digit (0) from the dividend and append it to 147, then repeat: 1470 / 402

Moving on to step 6:
1470 divided by 402 is 3 with a remainder of 264.
The next digit of our result is 3. 
Result so far: 1063.0
Subtracting 1206 from 1470 leaves us with 264.
Bring next digit (4) of the dividend behind the 264 and repeat the process: 2644 / 402

Advancing to step 7:
2644 divided by 402 is 6 with a remainder of 232.
Put 6 as the next digit of the answer. 
Result so far: 10636.0
The remainder is 232 after subtracting 2412 from 2644.
Append the next digit (2) from the dividend to 232 and continue with: 2322 / 402

Moving on to step 8:
When dividing 2322 by 402, we get 5 with a remainder of 312.
The number 5 becomes the next digit in our result. 
Result so far: 106365.0
If we take 2010 away from 2322, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 9:
3120 divided by 402 is 7 with a remainder of 306.
The number 7 becomes the next digit in our result. 
Result so far: 106365.7
If we take 2814 away from 3120, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 10:
402 goes into 3060 7 times with a remainder of 246.
Use 7 as the next digit of our solution. 
Result so far: 106365.77
Subtracting 2814 from 3060 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

After the division, we end up with 106365.77 and a remainder of 0.246.
