Let's divide 42786534 by 413
We're looking to find how many times 413 goes into 42786534.

On to step 1:
413 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 413

Moving on to step 2:
42 divided by 413 is 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 413

Moving on to step 3:
If we divide 427 by 413, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 413 from 427 leaves us with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 413

Going ahead to step 4:
If we divide 148 by 413, we get 0 and a remainder of 148.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 148, we end up with 148.
Append the next digit (6) from the dividend to 148 and continue with: 1486 / 413

Step 5:
The number 413 fits into 1486 3 times, leaving a remainder of 247.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Deduct 1239 from 1486 and we're left with 247.
Grab the next digit (5) from the dividend, add it to 247, then carry on: 2475 / 413

Moving on to step 6:
The number 413 fits into 2475 5 times, leaving a remainder of 410.
The next digit of our result is 5. 
Result so far: 1035.0
If we take 2065 away from 2475, we end up with 410.
Append the next digit (3) from the dividend to 410 and continue with: 4103 / 413

Advancing to step 7:
When dividing 4103 by 413, we get 9 with a remainder of 386.
Put 9 as the next digit of the answer. 
Result so far: 10359.0
The remainder is 386 after subtracting 3717 from 4103.
Include the next digit (4) from the dividend after 386, then repeat: 3864 / 413

Let's proceed to step 8:
3864 divided by 413 is 9 with a remainder of 147.
Put 9 as the next digit of the answer. 
Result so far: 103599.0
Subtracting 3717 from 3864 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 9:
413 can be fit into 1470 3 times, resulting in a remainder of 231.
The number 3 becomes the next digit in our result. 
Result so far: 103599.3
If we subtract 1239 from 1470, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 10:
2310 divided by 413 is 5 with a remainder of 245.
Write down 5 as next digit of the result. 
Result so far: 103599.35
If we take 2065 away from 2310, 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 11:
413 can be fit into 2450 5 times, resulting in a remainder of 385.
Put 5 as the next digit of the answer. 
Result so far: 103599.355
The remainder is 385 after subtracting 2065 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

The final outcome is 103599.355, with a leftover of 0.0385.
