We're dividing 42835340 by 387 
We want to divide 42835340 by 387.

Step 1:
When dividing 4 by 387, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 387

On to step 2:
When dividing 42 by 387, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 387

Step 3:
387 goes into 428 1 times with a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 41 after subtracting 387 from 428.
Grab the next digit (3) from the dividend, add it to 41, then carry on: 413 / 387

On to step 4:
387 goes into 413 1 times with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 387 from 413 and we're left with 26.
Take the next digit (5) from the dividend and append it to 26, then repeat: 265 / 387

Going ahead to step 5:
If we divide 265 by 387, we get 0 and a remainder of 265.
The next digit of our result is 0. 
Result so far: 110.0
The remainder is 265 after subtracting 0 from 265.
Append the next digit (3) from the dividend to 265 and continue with: 2653 / 387

Moving on to step 6:
If we divide 2653 by 387, we get 6 and a remainder of 331.
Use 6 as the next digit of our solution. 
Result so far: 1106.0
Subtract 2322 from 2653 to get 331.
Grab the next digit (4) from the dividend, add it to 331, then carry on: 3314 / 387

Let's proceed to step 7:
When dividing 3314 by 387, we get 8 with a remainder of 218.
Use 8 as the next digit of our solution. 
Result so far: 11068.0
Subtract 3096 from 3314 to get 218.
Append the next digit (0) from the dividend to 218 and continue with: 2180 / 387

Advancing to step 8:
When dividing 2180 by 387, we get 5 with a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 110685.0
If we take 1935 away from 2180, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 9:
387 can be fit into 2450 6 times, resulting in a remainder of 128.
The number 6 becomes the next digit in our result. 
Result so far: 110685.6
If we take 2322 away from 2450, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 10:
If we divide 1280 by 387, we get 3 and a remainder of 119.
Put 3 as the next digit of the answer. 
Result so far: 110685.63
The remainder is 119 after subtracting 1161 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 11:
1190 divided by 387 is 3 with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 110685.633
If we take 1161 away from 1190, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 110685.633, with a leftover of 0.0029.
