42335640 ÷ 335 
We want to divide 42335640 by 335.

On to step 1:
335 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 335

On to step 2:
When dividing 42 by 335, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 335

Advancing to step 3:
If we divide 423 by 335, we get 1 and a remainder of 88.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 335 away from 423, we end up with 88.
Grab the next digit (3) from the dividend, add it to 88, then carry on: 883 / 335

On to step 4:
335 can be fit into 883 2 times, resulting in a remainder of 213.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 213 after subtracting 670 from 883.
Include the next digit (5) from the dividend after 213, then repeat: 2135 / 335

Advancing to step 5:
335 can be fit into 2135 6 times, resulting in a remainder of 125.
The next digit of our result is 6. 
Result so far: 126.0
Subtracting 2010 from 2135 leaves us with 125.
Bring next digit (6) of the dividend behind the 125 and repeat the process: 1256 / 335

Step 6:
335 goes into 1256 3 times with a remainder of 251.
Record the quotient 3 as the next digit in the result. 
Result so far: 1263.0
The remainder is 251 after subtracting 1005 from 1256.
Bring next digit (4) of the dividend behind the 251 and repeat the process: 2514 / 335

Let's proceed to step 7:
335 goes into 2514 7 times with a remainder of 169.
The next digit of our result is 7. 
Result so far: 12637.0
The remainder is 169 after subtracting 2345 from 2514.
Grab the next digit (0) from the dividend, add it to 169, then carry on: 1690 / 335

Moving on to step 8:
When dividing 1690 by 335, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 126375.0
The remainder is 15 after subtracting 1675 from 1690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
If we divide 150 by 335, we get 0 and a remainder of 150.
The next digit of our result is 0. 
Result so far: 126375.0
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 10:
335 can be fit into 1500 4 times, resulting in a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 126375.04
Subtracting 1340 from 1500 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
The number 335 fits into 1600 4 times, leaving a remainder of 260.
The next digit of our result is 4. 
Result so far: 126375.044
If we take 1340 away from 1600, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The quotient of the division is 126375.044, and the remainder is 0.026.
